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

JPEG is what cameras and phones produce, and what most photographs arrive as. AVIF compresses better than both JPEG and WebP at the same visible quality, and keeps transparency.

This tool converts JPG to AVIF 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 .jpg or .jpeg or .jfif or .pjpeg or .pjp 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 AVIF file.

Limitations

  • Not every browser can write AVIF from a canvas. Where yours cannot, this tool says so rather than quietly producing a PNG with the wrong extension.
  • The output is lossy AVIF, so it is not a byte-exact copy of the original.
  • AVIF encoding in a browser is noticeably slower than the other formats.
  • Both JPG and AVIF 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.
