Why convert JPG to AVIF?
AVIF represents the current frontier of still-image compression for the web. Built on the AV1 video codec, it typically produces photo files roughly half the size of an equivalent JPG at matched perceptual quality. That's especially valuable for hero images, product galleries, and other LCP-critical content where every kilobyte affects page-speed scores. The trade-off is encode time: AVIF is 5-10x slower to encode than JPG because the AV1 codec does more analysis per pixel. For build-time pipelines or one-off conversions, that cost is invisible to end users — but it's why you wouldn't use AVIF for real-time transcoding of user-uploaded content without a dedicated encoder service.
50% size cut on photos
AV1's intra-frame compression beats JPG's 8x8 DCT blocks on virtually every real-world photo. Expect output files around half the source JPG size at matched perceptual quality.
Page-speed leverage
Smaller hero images and above-the-fold photos translate directly into better Largest Contentful Paint (LCP) scores. For performance-budget-sensitive sites, the AVIF swap alone can move the needle.
Modern color handling
AVIF supports 10- and 12-bit color depth natively. Gradients, night scenes, and skin tones hold up better than they do in 8-bit JPG — worth noting if you're converting photography shot in wide-gamut settings.
When JPG to AVIF pays off
AVIF is the strongest choice when page-speed and bandwidth matter more than encode simplicity.
Hero images and product photography on performance-sensitive sites.
Marketing photography with large render sizes where every KB affects LCP.
Build-time asset pipelines where the slower encode is invisible to end users.
Skip AVIF when your audience skews toward legacy Safari (<16.1), Samsung Internet, or older mobile browsers.

What you get
Every conversion here runs on a temporary copy, delivers a ready download, and clears out quickly after you’re done.
- Roughly half the file size of the JPG source at matched perceptual quality.
- 10-12 bit codec support preserves gradients and wide-gamut tone better than 8-bit JPG.
- Works natively in every current browser engine (Chrome 85+, Firefox 93+, Safari 16.1+).
- Conversion uses a temporary server-side copy that we delete right after.
Frequently asked questions
How much smaller will the AVIF actually be?
For typical photos, expect around 50% size reduction at matched perceptual quality. Some content compresses even more aggressively — low-detail landscapes can hit 60%+ reduction. Very noisy or highly detailed photos see smaller wins (30-40%) but still beat JPG.
Why does encoding take so long?
AV1 is a more complex codec than JPG's DCT or WebP's VP8. It does substantially more analysis per pixel to find better compression, which is the source of its size advantage. For a typical web-size image, encoding takes a few seconds. At build time or in batch pipelines, that's fine; for real-time transcoding you'd want a dedicated encoder service.
Is AVIF ready for production traffic?
Yes — browser support is ~95% globally as of 2025. Chrome, Edge, Firefox, and Safari all decode AVIF natively. If your audience includes meaningful Samsung Internet or older-Safari traffic, serve the AVIF via a <picture> element with a WebP or JPG fallback.
Will EXIF and color profile survive?
Yes. Sharp preserves EXIF and ICC color profile by default when encoding AVIF, so camera metadata and color-space info carry over. For a metadata-free AVIF, run the output through a metadata remover afterward.
AVIF vs WebP — which should I pick?
AVIF is typically 20% smaller than WebP at matched quality, so it's the stronger choice on compression alone. WebP has marginally broader browser support and faster encode. If you're shipping one format, use AVIF with a JPG fallback; if you're shipping two modern formats, use <picture> with AVIF first, WebP second.
