Short answer: digitizing a logo means rebuilding it as stitch instructions. Clean up the art, size it for the garment, give every shape a stitch type (satin, fill or running), set density, underlay and pull compensation for the fabric, put the objects in a sewing order with as few trims as possible, export the format your machine reads, and sew a test piece before the run.
An embroidery machine doesn't read pictures. It reads a list of needle positions, colour changes and trims. Digitizing is the job of writing that list so the thread lies the way the artwork looks. This guide walks through the steps in the order a digitizer actually does them, and what to check at each one.
1. Start from the cleanest artwork you have
Vector art (SVG, PDF, AI) is ideal because every edge is already a clean curve. A large PNG with solid colours is the next best thing. Screenshots, small JPEGs and logos with soft shadows take longer, because every blurry edge has to be decided by hand.
Before you digitize anything:
- Remove backgrounds, drop shadows, glows and gradients. Thread can't fade from one colour to another the way ink can.
- Reduce the logo to the colours you'll actually stitch. Two to six thread colours covers most logos.
- Decide what to leave out. A tagline that reads fine on a website is often too small to stitch on a left chest.
2. Size it for the garment first
Size decides almost everything else: which parts can be satin, which need to be fills, and whether small lettering survives at all. Set the final size before you draw a single object.
| Placement | Typical size |
|---|---|
| Left chest | about 3.5–4″ wide |
| Cap front | up to about 2.25″ tall, 4–4.5″ wide |
| Beanie cuff | about 2″ tall |
| Sleeve | about 3″ wide |
| Full back | up to about 12″ wide |
If you resize later, regenerate the stitches rather than stretching them. A digitized file stretched by more than 10–15 % on the machine ends up with satin columns that are too thin or too dense. See why stitch files shouldn't be scaled on the machine.
3. Give every shape the right stitch type
Look at each part of the logo and measure how wide it is:
- Under about 1 mm: a running stitch (a single line), or a bean stitch (a triple run) for a bolder line.
- About 1–8 mm: a satin column. Lettering, borders and outlines are almost always satin.
- Wider than that: a fill, usually tatami, with a satin or running border if the edge needs to look crisp.
The full reasoning, including where the satin limit really sits, is in Satin, fill or running stitch?.
4. Set the stitch angles
Thread reflects light along its length, so angle changes how a shape looks. Satin columns turn with the shape. Fills look best when neighbouring areas run at different angles, which is how a logo shows separation between two same-colour areas without an outline. Avoid running a large fill exactly horizontally on stretchy knits: the fabric pulls most across the rows.
5. Set density, underlay and pull compensation for the fabric
These three settings do most of the work of making a design sew cleanly:
- Density (row spacing): a standard satin or fill for 40 wt thread is about 0.40 mm between rows going the same direction. Open it up on light fabrics and small columns; tighten it only when fabric shows through.
- Underlay: the stitches sewn first, underneath. They hold fabric to the backing and lift the top stitches. Narrow satins get a centre run; wider ones get an edge run plus zigzag; fills get an edge run plus a light tatami.
- Pull compensation: thread tension pulls fabric in across the stitch direction, so shapes sew narrower than drawn. Each column is widened slightly to make up for it: a little on twill, more on knits and fleece.
Our guide to density and stitch count has the numbers.
6. Plan the sewing order
The order objects sew in matters as much as the objects themselves:
- Sew background shapes first and the details that sit on top of them last.
- Finish each thread colour in one pass where you can. Every colour change is a machine stop.
- Travel under later stitching instead of trimming when the next shape is close by. Trims cost time and leave tails.
- On caps, sew from the centre out and from the bottom up (see how to digitize for caps).
When we compared 122 hand-digitized production files from a working embroidery shop, the hand files averaged roughly one and a half trims per 1,000 stitches. That's a useful target. A file with several times that is spending a lot of machine time cutting thread.
7. Add lock stitches and check the trims
Every place the thread is cut needs a few tiny tie-off stitches before the trim and tie-in stitches after it, or the thread pulls out. Most software adds these automatically. Check that jumps longer than your machine's trim setting really are trimmed, and that short moves inside the design travel instead.
8. Export the right format
DST works on nearly every commercial machine, TAP on Happy, PES on Brother and Baby Lock, EXP on Melco and Bernina, JEF on Janome and VP3 on Viking and Pfaff. DST and TAP don't store thread colours, so send a colour list with the file. More in Embroidery file formats explained.
9. Sew a test piece
Always test on the same garment, or the same fabric with the same backing. Look for gaps between fills and outlines, letters that fill in, puckering, and anything that sewed in a surprising order. Fix the file, not the garment.
Doing this in EasyDigitizer
EasyDigitizer follows the same workflow. You pick the garment first, so density, underlay, pull compensation, hoop and sequencing start from that fabric. Then you drop in the logo and it builds the objects for you: satin, fill and running stitches chosen by width, angles set, sewing order planned. Every object stays editable with the hand tools, so you can fix anything the automatic pass got wrong before you export.
Frequently asked questions
How long does it take to digitize a logo?
A simple text logo takes a skilled digitizer 15–30 minutes. A detailed multi-colour logo can take a few hours. Auto-digitizing produces a first pass in seconds, and you then review and correct it.
Can I digitize a logo from a JPG?
Yes. A large, sharp JPG or PNG with solid colours works well. Small or blurry images still work, but you'll spend more time cleaning up edges and colours.
What size should a left-chest logo be?
About 3.5–4 inches wide is the usual range. Check that the smallest lettering is still at least about 4–5 mm tall at that size.
Do I need to digitize a logo again for a cap?
Usually yes, or at least re-plan it. Caps need a smaller height, centre-out sequencing and different underlay, so a left-chest file rarely sews well on a cap front as-is.
