ConvertWhat happens when you convert Sketch to JPEG
- JPEG is another name for JPG; files ending in .jpeg work here.
- Sketch files are converted from the preview image saved inside the file (the first page, up to about 2000 px), not re-rendered.
- JPEG uses lossy compression, so files get much smaller. Use the Quality slider to balance size and detail.
- JPEG has no transparency, so transparent areas are filled with a background color you choose (white by default).

Frequently asked questions
Is it safe to convert my files here?
Yes. Conversion happens entirely in your browser. Your files are never uploaded to a server, so nobody else can see them.
Is it free? Are there limits?
It's completely free, with no sign-up, watermarks or daily limits. The only limit is your device's memory for very large files.
Can I convert many Sketch files at once?
Yes. Drop as many files as you like; they're converted one after another and you can download them all as a ZIP.
Will converting Sketch to JPEG reduce quality?
JPEG is lossy, so some fine detail is removed to make the file smaller. At the default quality it's hard to see; raise the Quality slider to keep more.
Does JPEG keep transparency?
JPEG doesn't support transparency, so transparent areas are filled with a background color you can choose.
Are layers kept?
No. The file is flattened into a single image, exactly as it looks. Keep the original if you still need the layers.
Why is my Sketch image smaller than the design?
Sketch saves a preview image inside every file, and that preview is what gets converted. For full-size or per-artboard exports, export from the app itself.
