How it works
Click the dropzone above or drag a EXP from your desktop. Files of any size, there's no upload, so there's no upload limit.
The conversion runs entirely in this tab using JavaScript and WebAssembly. Your file never touches our servers, we don't have any.
Get your DST the moment the conversion finishes. Convert another, or close the tab.
Your file is never uploaded. The entire conversion runs in your browser using WebAssembly. We can't see what you convert because we have no server to see it.
Server converters cap free users at 1-2 GB and gate larger files behind a paid plan. Since nothing uploads, our limit is whatever your browser can handle.
No account required. No watermark on the output. No queue. Drop a file, get a converted file.
Why convert EXP → DST
EXP (Melco/Bernina) to DST (Tajima), the universal commercial format most machines accept. Convert to share a design widely or run it on a multi-needle machine.
You have an EXP design and need the widely-compatible DST. Convert here and load the .dst anywhere.
Where did the colors go?
Both EXP and DST rely on software for thread colors rather than storing a palette. Assign threads after importing; the stitches and stops are intact.
Formats involved
EXP is Melco's expanded embroidery format (also used by Bernina Artista). Simplest of the major formats: no header, just a stream of 2-byte stitch deltas with control codes for jumps, color changes, and end-of-design. Universal compatibility because of the format's simplicity.

DST is Tajima's industrial embroidery file format and the most universally-supported design format on commercial machines. 512-byte header followed by 3-byte stitch records. Brother, Janome, Bernina, Singer, Husqvarna Viking, all read DST as a fallback even when their native format is different.

Whatever your browser can hold in memory. Practically, this means a few hundred MB on most computers, significantly larger than the 1-2 GB caps that server-upload converters charge for. Very large files (multi-GB) may require closing other browser tabs first.
Melco and Bernina industrial/professional embroidery. Universal embroidery design interchange. The most common reason to convert is compatibility, DST works in places where EXP doesn't, or vice versa.

Once the page is loaded, the conversion itself runs entirely offline. The first time you use a tool, your browser downloads the conversion library (a one-time cache). If you reload while offline, the page won't load, but you can install the site as a Progressive Web App for full offline use.
Single file at a time for now. Batch conversion is on the roadmap, for now, drop one file, download the result, then convert the next.
