Lower quality means smaller files. 75–85 is a good balance.

Frequently Asked Questions

  • Are my images uploaded to a server?

    No. The conversion runs entirely in your browser using Canvas and WebAssembly, so your images never leave your device.

  • Should I use WebP or AVIF?

    Both are much smaller than PNG and JPG. AVIF usually produces the smallest files at the same visual quality but takes longer to encode, while WebP encodes fast and is supported by every modern browser.

  • Is transparency preserved?

    WebP, AVIF and PNG keep the alpha channel. JPG does not support transparency, so transparent areas are filled with white.

  • Can I convert WebP or AVIF back to PNG or JPG?

    Yes. Choose PNG or JPG as the output format. Any image your browser can open can be converted, including WebP, AVIF, GIF (first frame), BMP and SVG.
