Notes and limitations

A few limitations and notes worth knowing before you use the tool.

Images are never uploaded. All conversion happens in your browser.

JPEG does not support transparency, so transparent areas will be filled with white.

Animated sources such as GIF keep only their first frame; SVG and animated export are not supported.

FAQ

A few common questions before you start.

Will my image be uploaded?

No. Image processing happens entirely in your browser and files are never sent to the server.

Which image formats are supported?

You can import PNG, JPG/JPEG, WebP, AVIF, GIF, BMP and HEIC/HEIF (iPhone photos), and export PNG, JPG/JPEG or WebP. Animated sources such as GIF keep only their first frame.

Can I convert iPhone HEIC photos?

Yes. Just upload the .heic/.heif file — your browser decodes it locally and converts it to JPG, PNG or WebP, with no upload.

What happens to transparent backgrounds in JPEG?

JPEG does not support transparency. If the source image has transparent pixels, the exported JPEG will use a white background.
