Resize AVIF images in your browser

AVIF (AV1 Image File Format) is a newer format with some of the smallest photo files. Current browsers open it, but many older apps, editors and upload forms do not. This AVIF resizer shows the new size and file size live, keeps proportions, can hit a file size limit and handles up to 50 images at once. Nothing is uploaded.

How to resize a AVIF image

  1. Drop your AVIF files onto the page, press Choose images, or paste a picture.
  2. Pick how to set the size: Pixels, Percent or Preset.
  3. Check the live preview and the numbers under it. Open Settings for the format, quality or a file size limit.
  4. Press Download for the current image, or Download all to get every image in one ZIP file.

AVIF resizing questions

How do I resize a AVIF image?

Add your AVIF files with the box above, set a width and height, a percent or a preset, check the live preview and press Download. Everything runs in your browser, so nothing is uploaded.

Will resizing lower the quality of a AVIF?

Making a AVIF smaller keeps it sharp because it is reduced in steps. Lossy formats are compressed again when saved, and you can set the quality and a largest file size in Settings.

Is the resized AVIF saved as AVIF?

The resizer saves JPEG, PNG or WebP. A AVIF is saved as PNG by default, and you can choose JPEG or WebP in Settings.

What happens to transparency in a AVIF?

See-through areas stay see-through when the result is a PNG or WebP. A JPEG cannot be see-through, so those areas get the background colour you choose.
