The question comes up with every quote: “why pay €40 for a file when a website does it free in ten seconds?” The answer depends on the logo. Here is where automation wins, and where it falls short.
What an algorithm does
An automatic converter works in three steps: it segments the image by colour, vectorises the outlines, and fills each area with stitches. It is fast, repeatable, and free or nearly free.
On a simple logo — two or three flat colours, broad shapes, text of at least 8 mm — the result is very decent. Underlay is added automatically, density follows standard values, and the machine sews without surprises.
What a human digitizer does
They do not “convert”, they reinterpret. They look at the logo and decide:
- stitch order — what must go underneath to avoid bulk at crossings;
- stitch direction — 45° fills on a curved surface, vertical on a ribbon, horizontal on an elongated shape;
- stitch types — satin for a band, fill for a surface, running stitch for an outline;
- pull compensation — fabric contracts under stitches, so shapes are drawn slightly larger;
- underlay — one for stability, one for loft, one for crisp edges;
- how it will look on the garment — a logo that bleeds on a thin polo is fixed before it ships.
On a workwear piece, those decisions matter more than the file itself.
Case by case
| Situation | Automatic | Human |
|---|---|---|
| 2–3 colour logo, text ≥ 8 mm | Very good | Excellent, no visible gain |
| Text between 5 and 8 mm | Fine if the font is bold | Clearly better |
| Text < 5 mm | Unreadable | Readable, often with reduced density |
| Nested shapes, crests | Bulk at crossings | Handled through stitch order |
| Gradients and shadows | Avoid | Translated into blends or flats |
| Monograms, fine lettering | Poor | A specific craft |
| High volume, identical logo | Ideal | Only pays off for the first file |
The real criterion: the cost of failure
A bad file does not cost €40. It costs the garment, the time spent unpicking, and sometimes the order.
On an €8 test t-shirt, automation is a reasonable bet. On twenty polos embroidered with the company name, a density or underlay mistake shows on all twenty.
So the right question is not “automatic or human”, but “what does a failure cost on this order”.
The approach that works in practice
- Convert the logo automatically.
- Stitch one piece on a scrap of the actual fabric.
- If the result is clean — crisp edges, readable text, no puckering — keep the file.
- If not, have a digitizer rework it, giving them your DST and a photo of the test.
This removes 80% of nasty surprises for the price of a fabric scrap.
What to ask a digitizer
- the DST file and an editable source file;
- the stitch count and number of colours;
- a preview or a photo of a sewn sample;
- the revision policy, usually one or two rounds included;
- the licence: personal use, or resale on your garments.
Our position
Our converter is an automatic tool, and we do not claim it replaces a digitizer in every case. It is built for simple logos, quick tests, prototypes, and files you want within the minute.
When the logo is complex, the tool tells you in its own way: a preview with clogged details. That is the signal to bring in a human.
