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.

Will I lose quality when converting?

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

Can I convert several images at once?

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

Why is the AVIF output sometimes a PNG?

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

Does conversion remove transparency?

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

Format info

Converting PNG to BMP removes compression and stores raw pixel data, which makes files much larger. Use this when legacy software or an old workflow requires an uncompressed bitmap. Frespy re-encodes locally in your browser without uploading the image.
