What converts to what
Input: JPG, PNG, WebP, AVIF, HEIC/HEIF, GIF (first frame) and BMP. Output: JPG, PNG, WebP and AVIF. TIFF, RAW camera files, PSD and SVG are not supported.
- Transparency → JPG: JPG cannot store transparency, so transparent areas are filled with white or the colour you choose under Advanced.
- Animated GIF/WebP: only the first frame is converted.
- Colour: images are converted to standard sRGB. Wide-gamut and HDR photos may look slightly less saturated than on the device that took them.

Questions and answers
Can I convert several formats at once?
Yes. A batch can mix HEIC, PNG, WebP and JPG files; all of them are converted to the output format you choose.
Does converting reduce quality?
Converting to JPG, WebP or AVIF re-encodes the image with lossy compression; at quality 80+ the difference is very hard to see. Converting to PNG (Lossless mode) keeps every pixel of the decoded image.
What happens to EXIF data and GPS location?
Every output file is re-encoded from the pixels, so EXIF metadata such as GPS location, camera model and capture time is not copied into it. The photo is turned upright first, so removing the orientation tag does not leave it sideways.
Is there a limit on file size or number of images?
There is no upload limit because there is no upload. The practical limit is your device’s memory: images up to 100 megapixels (and 16,384 pixels per side) are accepted. Large batches are processed a few at a time.
Are my images uploaded to a server?
No. The images are read and compressed by code running in this browser tab, and the results are created in your device’s memory. Nothing is sent anywhere, which you can confirm in your browser’s developer tools (Network tab) while you work. See Privacy.
