How to convert to AVIF
This page converts any supported image into AVIF. AVIF is the newest of the mainstream web formats. It generally produces the smallest file of any of them at a given quality, supports transparency, and handles gradients and flat colour especially well.
- Click the Choose Files button and select any images you want as AVIF.
- AVIF is already selected. Change it on any individual file if you want a mixed batch.
- Click Convert, then download your AVIF files individually or as a ZIP.
Anything into AVIF
JPG, PNG, WebP, AVIF, GIF, BMP and TIFF can all be turned into AVIF here, in a single batch if you like, with no limit on how many files you drop in.
Keep the quality
Adjust quality per file and resize on the way through. Formats without transparency get a clean white matte instead of the black edges most converters leave behind.
Nothing is uploaded
Your files are read and written by your own browser. They are never sent to a server, so there is nothing to delete afterwards and no size or file-count limit.
More image tools
Everything below is built into this converter — no separate tool needed.
- Compress without converting — pick the same format as your input and lower the quality slider to shrink a file while keeping its type.
- Resize — open the gear on any file and set a maximum width; the height follows automatically.
- Images to PDF — choose PDF as the output to turn a photo or scan into a document.
- Make a favicon — choose ICO as the output to produce a browser icon from any square image.
What is a AVIF file?
AVIF stands for AV1 Image File Format. AVIF is the newest of the mainstream web formats. It generally produces the smallest file of any of them at a given quality, supports transparency, and handles gradients and flat colour especially well.
Support outside browsers is still patchy, and not every browser can create AVIF files even though nearly all can display them.
