At Pulse Merch in Cedar City, we ask every Southern Utah business to send us vector artwork first (AI, EPS, or a PDF with vector layers intact) when placing an embroidery order, with a high-resolution PNG or JPG as a backup. We digitize the art into stitch files in-house, so you never need to send us a machine format. Sending the wrong file type is the single biggest reason embroidery orders stall before production.
Which file types to provide, and why order matters
Vector files sit at the top of our list because they scale to any size without losing edge quality, and they convert cleanly when our digitizer builds the stitch path. An AI or EPS file built in Adobe Illustrator keeps shapes as math rather than pixels, so whether your logo ends up at 2 inches on a polo or 8 inches on a jacket back, the lines stay sharp going into digitizing.
When a vector isn’t available, a transparent PNG or a high-DPI JPG can work, but only if it’s exported at or near final size, somewhere in the 300 to 600 DPI range. A logo pulled from a website at 72 DPI and stretched up to embroidery size will look soft in digitizing software and often produces muddy, imprecise stitch outlines.
A few file types cause us to stop and request better art every time:
- Screenshots of logos, which carry compression artifacts and jagged edges.
- Low-resolution web JPEGs saved for email or social media use.
- Canva exports with no vector or true PDF equivalent, which typically output in RGB and often lack the true vector structure vendors need for production.
- Consumer formats like basic bitmap files that lose detail the moment they’re resized.
If a Canva file is all you have, let us know up front. In some cases we recreate the artwork in Illustrator before digitizing to ensure better results. We cover more of these submission pitfalls in our piece on design mistakes to avoid for custom apparel prints.
Preparing your artwork: size, strokes, color, and type
Once we have the right file type, the next job is making sure the artwork itself is embroidery-ready. A few adjustments at this stage save a lot of back-and-forth later.
- Set the art at final size before sending it. If your logo will sit at 3.5 inches wide on a left chest, build or export it at that size rather than a generic 8×10 canvas.
- Respect minimum height for small text and fine detail. Institutional brand guides commonly set a minimum reproduction height around 5 millimeters, or roughly 0.2 inches, and recommend screen printing below that threshold. Anything smaller than that tends to stitch into an unreadable blob.
- Convert all text to outlines or curves. This locks the font shape so nothing shifts or substitutes during digitizing.
- Remove hairline strokes and oversimplify where needed. Digitizing works by converting vector shapes into stitch paths, and fine details and very thin lines often disappear or clump once they hit thread. Strokes thinner than about 0.3 points are a common casualty.
- Specify colors by Pantone or brand hex code, not screen RGB, as explained in detail in why high-quality printing matters for your brand. Thread color matching depends on a real reference, not a monitor’s interpretation of a shade of blue.
- Skip gradients and soft drop shadows. Thread can’t blend colors the way ink or pixels can, so a gradient logo needs to be flattened into solid color blocks before it will embroider well.
Pro Tip: If your logo has small sub-text under a larger mark, like a tagline, consider dropping it for the embroidered version and keeping it for printed apparel instead.

Shop experience: common mistakes and what happens next
A client once sent a logo with a tagline set at 10-point type and expected it to embroider exactly like it printed on their letterhead. Once digitized, the small letters collapsed into loops of thread with no legible shape. We ended up redesigning the lockup without the tagline for the embroidered version and recommended screen printing for any application where the full wordmark needed to stay intact.
That’s why a sew-out is recommended on any logo with fine detail, dense text, or a lockup not previously run. A sew-out is a single stitched sample on scrap fabric that shows density, puckering, and whether small elements hold their shape. It adds time to the schedule and a sample fee but helps catch problems before a full production run. When a sew-out reveals trouble, we usually simplify the art, adjust stitch density, or suggest screen printing as the better route for that particular design.
When embroidery beats screen printing for your order
Embroidery earns its keep on small, simple logos that need to survive years of washing: left-chest marks on polos, hats, and heavy workwear where the raised thread texture reads as higher-end. Screen printing takes over once a design gets large, photorealistic, or loaded with more than a few colors, or when you want a soft hand feel on a cotton tee rather than a textured patch.
- Choose embroidery for logos under roughly 4 inches on structured garments like polos, caps, and jackets.
- Choose screen printing for full-back graphics, gradients, or any art with fine photographic detail.
- Choose embroidery when durability through repeated industrial laundering matters more than exact color reproduction.
- Choose screen printing when the design must stay soft to the touch on a fitted tee or performance shirt.
Thread coverage also changes how a design reads up close. A screen-printed logo lies flat and can hold crisp fine lines; an embroidered version always has a bit of texture and loses anything thinner than the stitch width. If your design was built for print and needs to move to embroidery, expect some simplification, and budget time for that redesign conversation. Our comparison of screen vs. digital printing covers the printed side of that tradeoff in more depth.
Order checklist: what to send and how to submit it
Getting a bulk embroidery order through production without delays comes down to sending a complete package the first time, not a single file.
- Name your files clearly, including job name, placement, finished size, and thread colors, so nothing gets mixed up on our production floor.
- Attach a one-page spec sheet noting intended placement (left chest, cap front, sleeve), finished width or height, and garment style or SKU.
- Bundle your best vector file along with a transparent PNG at final size as a backup, plus Pantone or brand color codes.
- Include an approval contact and deadline so we know who signs off on the digitized proof and by when.
- Expect a digitizing step and possibly a sew-out before full production starts. Both add a bit of time and a line item to your quote, and both protect you from a bad run.
- Confirm your proof approval in writing before we cut thread on the full order. A verbal “looks good” on a phone call doesn’t lock production the way an email reply does.
Pro Tip: Send your spec sheet and files in a single email thread rather than scattered across texts and separate messages; it keeps the approval trail clean if a dispute comes up later.
Common embroidery file formats and what they do
Once we digitize your artwork, it becomes a machine-readable stitch file rather than a graphic file. These formats exist in a handful of common types, each tied to particular machine brands and software ecosystems. DST is the most widely used format across commercial embroidery machines because it’s broadly compatible and strips the design down to stitch coordinates and color-change commands. PES is tied to home and some commercial Brother machines and tends to carry more design metadata alongside the stitch data. EXP is associated with Melco machines, common in production shops, and JEF is used by Janome equipment.
Each format stores the same basic information in a different structure: needle positions, stitch types, thread trims, and color change points. None of them are editable the way a vector file is. Once art becomes a stitch file, changing the design means going back to the original artwork and redigitizing, not opening the stitch file and tweaking it directly. This is part of why we don’t ask clients to supply these files themselves. Our team builds them in-house as the final production step, matched to the specific machine and garment running that job.
How embroidery file formats differ from standard graphic files
A standard graphic file, whether it’s an AI, PNG, or JPG, describes shapes, colors, and pixels meant for a screen or a printer. An embroidery stitch file describes something entirely different: a sequence of needle movements, stitch lengths, and thread color changes that a sewing head will physically execute. There’s no visual rendering built into a DST or EXP file on its own; it only becomes a recognizable logo once a machine actually stitches it out.
That distinction is why a vector logo can’t simply be renamed or batch-converted into a stitch format the way you’d convert a PDF to a JPG. Vector shapes have to be run through digitizing software, which interprets each shape and assigns stitch type, direction, and density before generating the machine file. A graphic file with a gradient or a drop shadow has no direct equivalent in thread, so the digitizer has to make a judgment call about how to represent it, which is part of why we simplify those elements before digitizing rather than after.
How embroidery machines read and execute a stitch file
A commercial embroidery machine doesn’t interpret your logo the way a printer interprets a PDF. It reads a sequence of coordinate instructions from the stitch file, essentially a list of exact needle drop points, and moves the hoop and needle through that sequence one stitch at a time. Color changes are flagged as stops in the file, which is why multi-color logos pause mid-run while the operator switches thread.
Because the machine is only following coordinates, it has no way to “clean up” a design that was poorly digitized. If the original file packed stitches too densely in a small area, the machine will still try to execute every one of them, which is how you get puckered fabric or thread buildup that looks like a knot. This is also why the digitizer’s density and stitch-type choices matter more than the garment or thread brand in determining how a finished logo looks and feels.
From artwork file to finished stitch file
The conversion process starts with your vector or high-resolution image and ends with a machine-ready file specific to the equipment running your order. Our digitizer imports your artwork into digitizing software and traces each shape, assigning a stitch type (fill, satin, or running stitch) based on the shape’s size and purpose. Small text typically gets a satin stitch for density and legibility, while large fill areas use a fill stitch pattern set at an angle that won’t flatten the fabric’s grain.
From there, the software calculates needle sequencing, stitch density, and underlay (a foundation stitch layer that stabilizes fabric before the visible stitching goes on top). The final output gets saved in the format matched to the machine scheduled for your job. This whole process is manual judgment supported by software, not a one-click conversion, which is why digitizing carries its own line item on a quote separate from the garment and labor cost.
Software used to build and edit embroidery files
Professional digitizing runs on dedicated software built specifically for stitch creation, distinct from the graphic design programs used to build your original logo. Wilcom and Hatch are two of the more common commercial digitizing platforms used in production embroidery shops, built around importing vector or raster art and manually assigning stitch paths, types, and sequencing.
On the open-source side, Ink/Stitch is a plugin that extends Inkscape into a basic digitizing tool, useful for hobbyists or small shops but limited compared to commercial platforms when it comes to handling complex multi-color lockups at production scale. None of these tools replace the judgment of someone who digitizes daily and knows how a given fabric and stitch count will behave once it’s actually sewn, which is the main reason we keep digitizing in-house rather than accepting a client-submitted stitch file sight unseen.
Why stitch type and density decisions matter
The stitch type and density chosen during digitizing determine as much about the finished look as the original artwork does. A satin stitch, made of tight parallel threads, suits narrow shapes like letters and thin borders because it builds a smooth, slightly raised edge. A fill stitch, which crosses back and forth to cover larger areas, suits broad shapes like a mascot body or a block letter but can look rough if the density is set too low.
Density, meaning how closely stitches are packed together, directly affects durability and hand feel. Too dense, and the fabric puckers or the thread sits stiff and board-like. Too sparse, and the backing fabric shows through between stitches, which looks unfinished and wears poorly over repeated washing. Getting density right depends on the fabric type as much as the artwork, which is one more reason we test complex designs with a sew-out before committing to a full production run rather than relying on digitizing software’s default settings.
What procurement managers get wrong about embroidery files
The biggest misconception we run into is that a “high enough resolution” image is interchangeable with a vector file. It isn’t. Resolution measures pixel density for screen or print output; it says nothing about whether shapes can be cleanly traced for stitching. A 4,000-pixel-wide JPG of a gradient-heavy logo is still a worse embroidery input than a simple two-color vector at a fraction of that file size.
The second gap is timing. Many buyers treat digitizing and sew-outs as optional add-ons rather than built-in steps, then get frustrated when a rush order can’t skip them. On a logo we haven’t stitched before, skipping the sew-out is how you end up with fifty finished jackets and a lockup that reads wrong at ten feet.
Our take: prioritize sending clean, simple vector art over worrying about file resolution, and build a sew-out into your timeline from the start rather than treating it as a delay. That single habit shift prevents more reorders than any other change we could recommend.

Getting a quote for your embroidery order
We check every incoming file before it reaches digitizing, flag anything that needs rework, and handle the full conversion from artwork to stitch file in-house. When a logo is complex or hasn’t run before, a sew-out is included in the quote so you see the result before full production starts.
A quote from us typically includes a digitizing estimate, a recommended final size based on your garment and placement, and an expected turnaround once art is approved. If you want the technical rundown on our process first, our embroidery process guide covers it step by step. When you’re ready to move forward, request a quote and we’ll start with a quick review of your current files.
FAQ
What’s the minimum logo size for embroidery?
Most shops, including ours, follow guidance of roughly 5 millimeters, or about 0.2 inches, as the smallest height for embroidered text or fine detail to stay legible. Below that, letters tend to close up into unreadable loops of thread, so we typically recommend screen printing instead.
What if I only have a JPG or PNG of my logo?
A high-resolution PNG or JPG can work as a fallback if it’s exported near final size, ideally in the 300 to 600 DPI range. If the file is low-resolution or pulled from a website, we’ll likely ask for a vector source or budget time to recreate the art before digitizing.
Do I need to send a DST or PES file myself?
No. Digitizing, the process of building a machine-readable stitch file, is a production step we handle, not something clients need to submit. Send us your artwork in vector or high-resolution raster form and we take it from there.
Why can’t Canva files go straight to embroidery?
Canva typically exports in RGB and doesn’t generate a true vector PDF, which embroidery digitizing depends on for clean shape tracing. If Canva is the only source file available, we often need to recreate the logo in Illustrator before it’s ready for stitching.
When should I choose screen printing instead of embroidery?
Screen printing fits better for large, highly detailed, multi-color, or photographic designs, and for garments where a soft hand feel matters more than texture. Embroidery holds up better on small logos placed on polos, caps, and heavy workwear that face repeated industrial washing.
