Which image formats can I convert between?

Common web formats including PNG, JPG, WebP, GIF, BMP and AVIF, in both directions.

Are my images uploaded?

No. Conversion runs entirely in your browser, so your pictures never touch a server.

Converting to a lossless format like PNG keeps full quality; JPG and AVIF use compression you can tune.

Yes, add multiple files and each one is converted to your chosen output format.

A few browsers cannot encode AVIF; when that happens the tool falls back to PNG and tells you.

Transparency is kept for formats that support it (PNG, WebP, AVIF) and flattened for JPG, which has no alpha channel.
