About the formats
AVIF
AVIF is the newest mainstream image format, built on the AV1 video codec. It produces the smallest files of any widely supported format — often half the size of JPEG at the same quality — with transparency and HDR support. Encoding is slower, but the savings are significant.
WebP
WebP is Google's web-focused format, supported by every modern browser. It typically lands 25–35% smaller than JPEG at comparable quality and also supports transparency, making it the workhorse choice for fast-loading websites.
Frequently asked questions
Are my AVIF files uploaded to a server?
No. The conversion runs entirely in your browser using WebAssembly codecs — your files never leave your device. After the first visit the converter even works offline.
Can I convert many files at once?
Yes — add as many files (or whole folders) as you like, convert them in one batch, and download everything as a single ZIP. There are no file-count or size limits.
Will I lose quality converting AVIF to WebP?
You stay in control: WebP quality is adjustable in the options panel, and the defaults are tuned to be visually indistinguishable for typical images. You can re-convert with different settings instantly.
