About AVIF and WEBP
AVIF .avif
A modern image format derived from the AV1 video codec. It compresses harder than JPEG or WebP at the same visual quality, and handles wide colour and high dynamic range.
Good for
- The smallest files of any format here at a given quality
- Transparency, animation, wide colour gamut and HDR
- Holds up better than JPEG at very low bitrates
Trade-offs
- Support is newest — older browsers and many desktop apps cannot open it
- Encoding is slow compared with JPEG
- Fine detail can smooth over at aggressive settings
image/avif
WebP .webp
Google's image format, designed to replace both JPEG and PNG. It can compress either way — lossy for photographs, lossless for graphics — and supports transparency and animation in both modes.
Good for
- Typically 25–35% smaller than JPEG at comparable quality
- Transparency in lossy mode, which JPEG cannot do at all
- One format covers photographs, graphics and short animations
Trade-offs
- Older software and some print workflows still will not open it
- Lossy WebP discards detail just as JPEG does
- Editing tools support it less consistently than PNG or JPEG

What changes when you convert AVIF to WEBP
You choose how much to keep
WEBP can compress either lossily or losslessly, so the quality setting decides the outcome rather than the format. High quality stays close to the AVIF you started with; lower settings trade visible detail for a much smaller file.
Camera data is removed by default
A AVIF straight from a phone or camera carries EXIF metadata — model, settings, timestamp and, quite often, the GPS coordinates of where the photo was taken. The converted WEBP is written without it, so a file you are about to share does not quietly carry your location. The orientation flag is read and applied to the pixels first, so the image will not come out sideways once the tag holding it is gone. If you need the metadata kept, there is a setting for it.
How the WEBP is written
Our default is quality 82, with the encoder choosing colour subsampling per image rather than applying it blindly. The quality control on the converter moves this if you need to — the default aims to be indistinguishable from the source at a sensible file size, rather than to win a compression benchmark.

Where your transparent background went
Transparency is the property most often lost silently in a conversion — the file looks perfect until it lands on a coloured background and grows a white rectangle.

WebP or AVIF: choosing a modern image format
Both beat JPEG comfortably. They differ in how much they beat it by, how long they take to produce, and what will refuse to open them.
