About AVIF
AVIF is a modern image format based on the AV1 video codec, producing files significantly smaller than JPG at the same quality. Modern browsers (Chrome 85+, Firefox 93+, Safari 16+) decode AVIF natively, so this conversion runs entirely in your browser - your file never leaves your device.
Why convert AVIF to WEBP
WEBP delivers 25-35% smaller files than JPG or PNG at comparable quality and supports transparency. All modern browsers (Chrome, Firefox, Safari, Edge) support it natively.
Privacy and processing
Modern browsers decode AVIF natively, and the JPG, PNG, or WEBP output is encoded with the Canvas API. The image never uploads to a server.
AVIF to WEBP online with ImgShifter
AVIF to WEBP solves a pipeline problem: AVIF is the most efficient format, but efficiency means nothing when a CMS, image CDN, editor plugin, or build tool in your chain doesn't read it. WEBP is the pragmatic step down - nearly a decade older, supported by virtually everything that touches web images, and still far smaller than JPG or PNG.
The conversion runs on your device: native browser AVIF decode (Chrome 85+, Firefox 93+, Safari 16+) feeding a local WEBP encode, with full alpha-channel preservation throughout - no white-flattening, no server round trip. Expect the WEBP to come out 20-40% larger than the AVIF for typical photos; that's the compression generation gap, not a flaw in the conversion.
Use it when a tool rejects your AVIFs, when collaborators need files their software opens, or when you're standardizing a mixed asset folder onto the most compatible modern format. Like every browser-side ImgShifter tool, it keeps working with the internet disconnected.
