Why use this tool?

  • WebP and AVIF are considerably smaller than PNG or JPEG for the same picture, which makes pages faster.
  • Some software still refuses anything but JPEG or PNG, so converting back is as necessary as converting forward.
  • Transparency has to go somewhere when you move to JPEG; choosing the colour is better than letting a converter pick black.

How to use Image Format Converter

  1. Add the images you want to convert.
  2. Pick the output format and, for lossy formats, the quality.
  3. If the source has transparency and the target does not support it, choose the background colour.
  4. Convert and download, individually or as a zip.

Frequently asked questions

Which format should I use on a website?

WebP for almost everything: it is widely supported and much smaller than PNG or JPEG. AVIF is smaller still but slower to encode and slightly less supported.

What happens to a transparent background when I convert to JPG?

JPEG cannot store transparency, so it is filled with a solid colour. This tool lets you choose which one instead of defaulting to black.

Can I try this Pro tool without an account?

Yes. Convert one image and see the result at up to 640 pixels. Pro saves full-size files and converts batches. Your own input is processed locally in your browser.

Will upgrading keep my work?

Checkout and login open in a separate tab. Keep the workspace open to retain inputs, settings and previews. Files stay in that tab only; keep the originals in case you close or reload it. Export access is checked with the server after payment.
