Lower quality means a smaller file and visible artefacts. This has no effect on PNG, which is lossless.
Leave both empty to keep the original size.
When off, the image is stretched to exactly the width and height you give.

About this tool

AVIF comes from modern web pipelines and newer phone cameras. WebP is typically 25 to 35 percent smaller than JPEG at the same visible quality, and unlike JPEG it keeps transparency.

This tool converts AVIF to WebP entirely in your browser. The image is decoded, drawn, and re-encoded on your device, so nothing is uploaded and the size of the file costs you no waiting.

How to use it

  1. Choose a .avif file, or drag one onto the page.
  2. Pick a quality level.
  3. Optionally set a width or height to resize at the same time.
  4. Select Convert, then download the WebP file.

Limitations

  • Older browsers cannot decode AVIF; this page checks before offering it.
  • The output is lossy WebP, so it is not a byte-exact copy of the original.
  • A few older programs, email clients, and design tools still cannot open WebP.
  • Both AVIF and WebP are lossy, so this conversion adds a second round of loss on top of whatever the original already had. Convert from an original whenever you can.
  • Metadata is not preserved. EXIF fields, including camera settings and GPS location, are dropped, which is a privacy benefit but worth knowing if you rely on them.
  • Colour profiles are not preserved, so an image in a wide-gamut profile may shift slightly.
  • The camera's EXIF orientation is applied, so a photo taken sideways comes out upright rather than rotated.

Frequently asked questions

Is my image uploaded?
No. The conversion runs entirely in your browser. The image never leaves your device and no request carrying it is made.
Which quality should I choose?
85% is a good default for photographs and is usually indistinguishable from the original at normal viewing size. Lower settings become visible on sharp edges and in smooth gradients such as skies.
Can I resize while converting?
Yes. Set a width, a height, or both. With proportions kept, one dimension is derived from the other, and giving both fits the image inside that box rather than distorting it.
