Questions
Which images can I upload?
PNG and JPG, up to 4 MB and 24 megapixels. The format is read from the file’s bytes, not its name. GIF, WebP, HEIC and PDF are not accepted: export a PNG first.
Which files do I get?
SVG (one group per colour, millimetres) and, with a pass, DXF R12 (one layer per colour, closed polylines, millimetres). Not EPS, PDF, AI or embroidery formats.
How big will it be?
Pixels × 25.4 ÷ DPI millimetres. The preview shows the size before you download; change the DPI to change it.
What resolution is traced?
The preview and the free SVG are traced at up to 480 px on the longest side; a pass traces at up to 3000 px. Larger images are reduced first by averaging, which keeps edges smooth.
How many colours can it separate?
2 to 8. Choose the number of inks or threads plus one for the background.
Do you store my image?
No. It is traced in memory and dropped when the answer is sent; nothing is written to disk, to a database or to a log, and the file name is used only to name your download.
What do you store, then?
For the free tier, a hashed network address, the day and a keyed fingerprint of each image (so the same image is not counted twice), deleted after 7 days. For a pass, your e-mail, the order and the fingerprints of the images used on it (kept 30 days). Details on the privacy page.
Why did my free trace say “limit reached”?
The free tier is 2 different images a day per network address, reset at midnight UTC. On a shared network (an office, a school) others may have used them.
I lost my pass code.
Use the recovery page: it e-mails every code bought with your address.
Can I use the files commercially?
The files are yours to use as you wish, provided you have the rights to the image you traced. Tracing someone else’s logo or artwork does not give you rights to it.
Who runs this?
Janolab Studio LLC, Austin, Texas. Payments are handled by Paddle, the merchant of record.
