What happens when you convert WebP to AVIF?

Animation-capable destination

Still image output. Animated files use only the first frame; animation is not preserved.

Encoding mode

AVIF can use lossy or lossless AV1 coding. Chroma subsampling, RGB↔YUV conversion and reduced bit depth can change source values even when the AV1 coding stage is lossless. Quality defaults to 55; adjust it in Advanced options. File size depends on the image and encoder.

Is WebP → AVIF right for you?

Good choice when

  • AVIF fits your delivery use: Photo delivery & HDR images.
  • Your destination supports the required animation variant.
  • You need a transparency-capable destination and will check its supported variant.
  • Your receiving application supports the required AVIF variant.

Probably not when

  • You require guaranteed animation transfer from the unavailable converter.
  • You assume format-level alpha support guarantees matching transparent edges.
  • You need a guaranteed output file size or archival pixel equality. Encoder settings do not guarantee either.
  • You require identical samples without a defined colour and precision policy.

WebP to AVIF conversion details

Animation-capable destination
Still image output. Animated files use only the first frame; animation is not preserved.
Transparency representation
The implemented target supports alpha. Display-pixel processing can round translucent samples; archival sample equality is not promised.
Encoding mode
AVIF can use lossy or lossless AV1 coding. Chroma subsampling, RGB↔YUV conversion and reduced bit depth can change source values even when the AV1 coding stage is lossless. Quality defaults to 55; adjust it in Advanced options. File size depends on the image and encoder.
Sample precision & colour
Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
Metadata & colour
Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
Compression
WebP: Lossy & lossless → AVIF: Lossy & lossless WebP: Lossy VP8 and lossless VP8L are different coding modes. Lossless WebP preserves supported 8-bit samples, not higher-precision source values. Encoding options can also change RGB values under fully transparent pixels. AVIF: AVIF can use lossy or lossless AV1 coding. Chroma subsampling, RGB↔YUV conversion and reduced bit depth can change source values even when the AV1 coding stage is lossless.
Transparency
Transparency is replaced with white by default. Change the background in Advanced options.
Animation
Still image output. Animated files use only the first frame; animation is not preserved.
Colour depth
WebP: 8 bits/sample → AVIF: 8 / 10 / 12 bits
HDR
AVIF: Optional; colour properties
Dimensions
Rendered image dimensions are retained within the converter limits; this tool does not offer resizing. Orientation handling depends on the source decoder.
Metadata
Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.

Common questions

Can the animation be transferred between formats?

Still image output. Animated files use only the first frame; animation is not preserved.

Which compression mode will AVIF use?

AVIF can use lossy or lossless AV1 coding. Chroma subsampling, RGB↔YUV conversion and reduced bit depth can change source values even when the AV1 coding stage is lossless. Quality defaults to 55; adjust it in Advanced options. File size depends on the image and encoder.

Are bit depth and colour values guaranteed to match?

Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.

Will metadata and colour profiles be retained?

Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
