Convert AVIF to WEBP

Drop your AVIF files below. They are converted on your own device and never sent anywhere.

Convert to WebP when an AVIF has to work somewhere older — a CMS that rejects the upload, a design tool, or a mail client — and you still want the file to stay small. It is converted by your own browser here, so the file is never uploaded.

Nothing is uploaded. Your files are read by this page and processed by your own processor. Open the Network tab and watch — you will not see them leave.

AVIF and WebP, and why you would move between them

Both of these are modern web formats, so converting between them is not about rescuing a file from obscurity — it is about trading a little efficiency for a lot of compatibility. AVIF is smaller at the same quality, but WebP has around five more years of support behind it, and that gap is exactly where most of the problems live.

WebP is readable by every browser released since roughly 2020, by current versions of Photoshop, Figma and Office, and by most content management systems. AVIF is readable by browsers and not much else. If the file is going anywhere other than straight onto a web page, WebP is the more useful of the two.

Things that catch people out

  • This is a lossy-to-lossy conversion: the AVIF is decoded and re-encoded, so a second round of compression is applied on top of the first. At sensible quality settings it is not visible, but it is not free either.
  • Expect the WebP to be 20–40% larger than the AVIF at matching quality. That is the compatibility you are buying.
  • AVIF images using HDR or a wide colour gamut will be flattened to standard range, which is most noticeable in bright highlights.
  • Transparency survives the conversion intact in both directions.

Questions

Should I use AVIF or WebP on my website?

Serve both if your setup allows it: AVIF with a WebP fallback covers everything and gives the smallest file to browsers that can take it. If you can only pick one, WebP is the safer default, and the size difference is not usually decisive.

Does converting AVIF to WebP lose quality?

A little, because the image is decoded and re-encoded rather than repacked. Starting from a high-quality AVIF and encoding WebP at quality 80 or above, the difference is very hard to see.

What BriskFile will not do to you

  • Your files never leave your device

    Every conversion runs in your browser. Open DevTools, watch the Network tab, and you will see no upload — because there is not one.

  • No account, no email, no watermark

    Nothing to sign up for and nothing stamped on your images. There is no step between choosing a file and getting it back.

  • No limits at the download button

    No daily cap, no file counter, no "upgrade to download". If the tool starts a job, it finishes it.

  • Checkable, not just claimed

    Open the Network tab and convert something — nothing goes out. Or load the page, disconnect, and watch it keep working: the tool is already on your machine, and your file never leaves it.
