How to digitize a logo for embroidery, step by step

For a clean logo with bold shapes and text at least 6 mm tall, an automatic tool gives a sewable file in seconds for a few dollars. For small text, fine detail, caps or a large production run, a professional digitizer is worth the cost. Doing it yourself makes sense if you will digitize often and want to learn.

The rest of this guide explains the decisions behind a good logo file, whichever way you make it. Knowing them helps you prepare the artwork, judge an automatic result or brief a digitizer. Our picture to embroidery file guide compares the options in more detail.

Embroidery is made of solid areas of thread, so a logo has to be reduced to flat shapes in a limited number of colours. Work from the cleanest source you have: an SVG, or a PNG exported from the original vector file, is far better than a screenshot or a JPG that has been through email a few times.

What to remove or change:

• Gradients, glows and drop shadows. Thread can't fade. Replace a gradient with one or two flat tones, and drop shadows entirely unless they are a solid offset shape.
• Hairline outlines. Anything thinner than about 1 mm at the final size can't be a satin. Thicken it to 1–1.5 mm or remove it.
• Near-identical colours. Two blues that differ by a few percent will be sewn in the same thread anyway. Merge them.
• Tiny marks. A ® or ™ below 4 mm is a knot, not a symbol. Most brand guidelines allow leaving them off embroidered goods; check yours.

Keep the colour count low. On a single-needle home machine every colour is a stop where you re-thread by hand, and on any machine more colours mean more trims. Most logos read perfectly well with 3–6 thread colours, and the fabric colour can stand in for one of them: a white logo element on a white shirt is often better left unstitched.

It depends on the width of each shape at the final size: running stitch for lines under about 1 mm, satin columns from about 1 to 7 mm, and fill (tatami) for anything wider. Lettering follows the same rule, which is why capital letters need to be at least 6 mm tall.

In more detail:

• Under about 1 mm wide: running stitch. A single run for fine details, or a triple (bean) stitch when the line should look bolder.
• About 1–7 mm wide: satin column. The needle zigzags from edge to edge, giving the raised, glossy look people associate with embroidery. Below 1 mm a satin doesn't cover; above 7–8 mm the stitches become long enough to snag and lie loose, so wider shapes switch to split satin or fill.
• Wider than about 7 mm: fill (tatami). Rows of short stitches, typically 3–4 mm long with a row spacing around 0.4 mm, laid in a staggered pattern so no visible lines form.

Lettering follows the same logic with extra care. Keep capital letters at least 6 mm (about 1/4 in) tall in a sans-serif font; the strokes of letters that small are only about 1 mm wide, which is the floor for a satin. Serif fonts, thin script fonts and lowercase letters with a small x-height need to be bigger, often 8 mm or more. If the tagline can't reach that size, it is better to drop it than to sew something no one can read.

Use stitch direction deliberately. Fills sewn at different angles in neighbouring shapes catch the light differently, which separates two areas of the same colour. Satin columns should turn with the shape, so the stitches stay roughly perpendicular to the column's edges.

Start with a row spacing of 0.4 mm for fills on stable woven fabric, slightly lighter (0.42–0.45 mm) on knits, an underlay that matches the width of each shape, and 0.2–0.4 mm of pull compensation per side. Then adjust after a test stitch-out on the real fabric. These three settings decide whether a design looks crisp or puckered.

Density is the spacing between rows or satin stitches. A spacing of 0.4 mm is the usual starting point for fills on stable woven fabric. Stretchy knits do better slightly lighter, around 0.42–0.45 mm, because heavy stitching on a knit distorts it. Towels need a little more coverage so the loops don't poke through. As a rough guide, a fill at 0.4 mm spacing with 3.5 mm stitches puts about 70 stitches in every square centimetre before underlay, which is why a solid 100 × 100 mm block easily runs past 7,000 stitches on its own.

Underlay is a light layer sewn first to anchor the fabric and give the top stitches something to sit on:

• Centre run for narrow satins (under about 2 mm).
• Edge run for medium satins, roughly 2–4 mm.
• Zigzag (often combined with an edge run) for wide satins.
• A loose tatami or grid underlay under fills, sewn at an angle to the top fill.

Pull compensation widens shapes slightly, because thread tension pulls the fabric inward across the stitch direction. Values of 0.2–0.4 mm per side are typical: less on firm fabrics like denim, more on knits. Without it, satin letters sew thinner than drawn and fills pull away from their outlines, leaving gaps of fabric showing through. Fills also push outward at the ends of their stitches, so a circle sewn with horizontal rows comes out slightly wider than it is tall.

Sequencing is where good digitizing saves time and thread. The general rules:

1. Sew from the back of the picture to the front: background fills first, details on top.
2. Sew a shape's fill before its satin outline, so the outline covers the raw fill edge and hides small registration shifts.
3. Finish everything in one colour before moving on, unless the layering truly requires a return.
4. Work outward from the centre or move in one direction across the design, so the fabric is pushed consistently rather than in all directions.
5. Route travel stitches under areas that will be covered later, instead of jumping, to cut the number of trims.

On caps the order matters even more: a cap frame sews best from the centre outward and from the bottom up, so the crown is not pushed into a bubble. That's why a logo digitized for a flat shirt often needs its own cap version rather than just a smaller copy.

Even experienced digitizers sew a test before running a batch. Use the same fabric, stabilizer, needle and thread as the real job, and read the result:

• Fabric showing between a fill and its outline: the fabric moved. Add pull compensation, increase overlap, or use a firmer stabilizer.
• Puckering around dense areas: too many stitches for the fabric, or a stabilizer that's too light. Reduce density slightly or switch to cut-away. Our stabilizer guide covers which one to pick.
• Letters closing up: the text is too small for its stroke width. Enlarge it or use a bolder font.
• Thread breaks in one area: often too many stitches stacked in the same spot. Lower density or remove a layer.

For a sense of scale, our coffee badge sample is 96 × 96 mm with four colours and comes out at about 12,300 stitches. A logo in that range takes roughly 20–30 minutes on a typical single-needle home machine, plus colour changes.

StitchMyPic automates the steps above. Upload your logo as an SVG or a clean PNG, set the stitched size and the number of colours, and the converter decides for each shape whether it should be a satin column, a fill or a running stitch, adds underlay and pull compensation, and plans the sew order to keep jumps and trims down. Pick the fabric in the editor (woven, knit, cap, towel, denim or leather) and density, pull compensation and underlay are adjusted for it.

The stitch preview is free, so you can try different sizes and colour counts until the smallest text reads well. When you're happy, one download (1 credit, see pricing) gives you a ZIP with PES, DST, JEF and EXP. For the next 7 days you can re-export at another size and the stitches are recalculated, not just stretched.

We'd rather be honest about limits: a logo with very small text or a lot of fine detail may still benefit from manual work by a professional digitizer. For most clean logos, though, an automatic conversion gives a solid, sewable file. Start from SVG to PES for Brother machines or PNG to DST for commercial machines.
