WebP to AVIF Details

This page is a single-purpose converter: it rewrites WebP files as AVIF. Drop a file in, run the conversion, take the download.

WebP is the modern web format built to undercut both JPG and PNG at the same visual quality. AVIF is the still-image half of the AV1 codec and holds detail well even at low bitrates.

How to use it

The order below follows the page itself, and no step asks you to sign up or confirm anything.

  1. Drag your WebP files onto the upload area, or click it and pick them from the file dialog.
  2. The queue takes up to 20 files at once, and anything added by mistake can be removed from the list.
  3. The convert button rewrites the selected file as AVIF; the batch button repeats that for every WebP file in the queue.
  4. Rename the output in the queue field before downloading; the extension is set to AVIF for you.
  5. Click the download link on the finished row and the AVIF file lands on your device.

Formats, limits and behaviour

A few details that make the decision easier:

  • Accepted input: WebP (webp), up to 24 MB per file.
  • The result is written as AVIF and encoded at quality 60, which is why the file shrinks so much.
  • The queue carries 20 files at a time, and each file travels in its own request.
  • Transparent pixels survive the trip because AVIF supports an alpha channel.
  • Both sides are lossy, which means the image is encoded once more. Avoid converting the same file back and forth.
  • Do not count on metadata surviving: whether EXIF and ICC data travel depends on the engine handling the file, so keep anything critical elsewhere.

When to choose this tool

Choose it when there is a concrete reason to use AVIF rather than WebP. Hero images, high-resolution photography and pages that pay attention to mobile data cost benefit most. It usually lands smaller than WebP at matching quality, but encoding is slower and old software support is thin. WebP is the modern web format built to undercut both JPG and PNG at the same visual quality.

AVIF gives you the smallest file when page speed is the priority. If the file has to open in older software, WebP or JPG output is the safer call.

Practical notes

  • Add every WebP file from the same folder in one go; up to 20 of them finish in a single round.
  • Renaming outputs in the queue keeps your downloads folder readable once several AVIF files land there.
  • AVIF is encoded with loss, so converting the same file repeatedly costs quality. Keep the original.
  • Before publishing, confirm the destination accepts AVIF; some upload panels keep a short format list.

Where your data is processed

Processing an image means uploading it, and that upload lives only as long as the request. Once the output exists, the file is not stored and never handed to a third party. Ads may appear on the page, but no ad network can reach your upload.

Frequently asked questions

Drop your WebP file into the upload area, start the conversion, and download the finished AVIF file. No installation or plugin is needed.

You can add up to 20 files to the same queue. The per-file size limit is shown under the upload area.

Check that the file really is in WebP format and stays under the size limit. Partially downloaded or corrupted files cannot be read.

Lossless formats keep sharp edges and text clean, while smaller formats are better when page speed matters. Try both and compare the file sizes.
