Convert JPG to AVIF
The fastest way to convert JPG to AVIF: drop the JPG here and press Convert, since this page already targets AVIF. Your photo is encoded by an AV1 encoder running locally in the browser, so it is never transmitted anywhere.

Why convert JPG to AVIF?
AVIF is the deep-compression option for photographs. Against a quality-matched JPG it commonly saves 40-60%, and it shines exactly where JPG embarrasses itself: smooth skies and gradients that JPG turns into visible bands stay clean in AVIF at a fraction of the size. If your delivery targets are modern browsers, converting JPG photos to AVIF is the single biggest image-weight reduction available today. For email, documents and uploads to third-party services, keep a JPG copy; AVIF acceptance outside browsers remains patchy.
What is JPG?
JPG (or JPEG, for the Joint Photographic Experts Group that standardized it in 1992) is the most widely supported image format ever shipped. It uses lossy DCT compression tuned for photographs, which buys small files at the cost of discarding fine detail, and it has no transparency support. Practically everything that can open an image can open a JPG.
What is AVIF?
AVIF (AV1 Image File Format) is the newest mainstream image format, published by the Alliance for Open Media in 2019 on top of the royalty-free AV1 codec. It delivers the strongest compression of any widely deployed format, especially at low and medium quality, and adds an alpha channel, HDR and 10/12-bit color. Browser support landed in Chrome 85, Firefox 93 and Safari 16, but much desktop software still cannot open an .avif file.
Quality and what to expect
Lossy-to-lossy transcoding applies: the encoder inherits whatever artifacts the JPG already had and adds its own subtle smoothing, so archive the source. AVIF tends to soften very fine grain and texture slightly more than JPG at aggressive settings, while handling gradients and flat regions far better. Encoding is the slowest on this site; AV1 trades CPU time for bytes, and multi-megapixel photos can take a number of seconds. Metadata, including GPS EXIF, is dropped in the output.
JPG to AVIF FAQ
How much smaller will AVIF be than my JPG?
Typical photos land 40-60% smaller at comparable visual quality. Already heavily compressed JPGs see less benefit. Gradient-heavy images see the most dramatic wins because AVIF avoids the banding JPG would need extra bytes to hide.
Why does this conversion take longer than the others?
AV1 encoding is computationally heavy by design; that effort is where the compression comes from. The work runs in a background worker so the page stays responsive while it grinds.
Can I put AVIF photos in an email or Word document?
Better not to. Mail clients and office software mostly cannot render AVIF yet. It is a web delivery format: superb behind an img tag in a modern browser, awkward everywhere else.
Does hushvert keep a copy of converted photos?
No copy exists to keep. The conversion pipeline is WebAssembly inside your browser; the photo bytes never leave your machine, so there is nothing on our side to store, scan or delete.
