AVIF

AVIF is a modern image format based on the AV1 video codec. It offers much better compression than JPG at similar quality and supports transparency, high dynamic range, and wide color. Current browsers support AVIF, but some older apps and editors cannot open it yet.

WEBP

WebP is an image format developed by Google for the web. It supports lossy and lossless compression, transparency, and animation, and its files are usually smaller than JPG or PNG. All modern browsers support WebP, but some older apps and editors cannot open it.

What happens when AVIF becomes WEBP

Source format

AVIF can use lossy or lossless compression and supports transparency and high bit depth.

Target format

WEBP supports lossy and lossless compression, transparency, and animation.

What changes

The AVIF pixels are decoded and written using WEBP compression and color capabilities.

What is preserved
Pixel dimensions and visible composition are preserved unless resize or crop settings are selected.
What may be lost
Layers, editable vectors, camera-raw controls, animation, high bit depth, and metadata are preserved only when WEBP supports them.
Codec and quality implications
Color profile handling, bit depth, chroma sampling, and compression settings can change appearance or file size.
Realistic limitations
Multi-page, layered, animated, camera-raw, or very large images may be flattened, reduced to one frame, or rejected if the decoder cannot safely read them.

Conversion steps

  1. Upload a AVIF file no larger than 1 GB.
  2. Confirm that WEBP is selected as the target.
  3. Download the WEBP file and check the result before deleting your source.

Troubleshooting

The AVIF file is rejected or will not open.
Confirm that the file is not empty, password-protected, or corrupt and that its real format matches the extension.
The WEBP file is larger than expected.
Choose a more efficient codec or lower quality setting when available. Lossless and uncompressed targets are often larger by design.
Transparency, color, or animation changed.
Choose a target that supports the needed feature and keep the original file; JPG cannot store transparency or animation.

Privacy and file retention

Uploads and converted files are processed automatically and irreversibly deleted within 24 hours. You can delete them sooner with the delete control. Convertr does not read, mine, sell, or manually review file contents.
