Why convert TIFF to AVIF?
TIFF to AVIF is the maximum-compression path from archive to web. Where WebP typically produces files 10-20x smaller than TIFF, AVIF goes further — often 15-30x smaller at matched visual quality — by leveraging the AV1 video codec's intra-frame compression. For performance-sensitive sites pulling assets from a TIFF-based archive, this is the most aggressive move available. The main trade-off is encode time, which is noticeably slower than WebP or JPG because AV1 does more analysis per pixel. Multi-page TIFF collapses to the first page, CMYK converts to RGB automatically, and 16-bit TIFF downsamples to 8-bit. AVIF retains transparency, so masked editor exports carry their alpha channel onto the web.
Maximum archive compression
AVIF's AV1-based compression is the most efficient widely-supported still-image codec. Expect 15-30x size reduction from TIFF sources at visually matched quality.
Transparency preserved
AVIF's full alpha channel translates RGBA TIFF transparency directly. Masked editor exports and scanned assets with cut-outs survive cleanly.
Page-speed leverage
On sites where archive content drives LCP or bandwidth budget, AVIF compression translates directly into measurable page-speed improvements without sacrificing perceptual quality.
When TIFF to AVIF is the strongest move
AVIF wins on size when your audience is on modern browsers and encode time isn't a user-facing constraint.
Archive content on performance-sensitive sites where every KB affects LCP.
Build-time asset pipelines converting archive TIFFs once, serving forever.
Modern-browser-majority audiences (Chromium, Firefox, Safari 16.1+).
Skip AVIF if your audience includes meaningful Samsung Internet or older-Safari traffic without <picture> fallback infrastructure.

Frequently asked questions
Why is AVIF better than WebP for TIFF sources?
AVIF's AV1 codec is more efficient than WebP's VP8 — typically 20% smaller at matched quality. For large TIFF sources being pushed to the web, that additional 20% compounds into meaningful bandwidth savings. The trade-off is slower encode, which doesn't matter for one-off or build-time conversion.
How long does TIFF to AVIF encoding take?
A few seconds per typical archive TIFF. Larger sources (above 50 MB) may take 10-20 seconds. Because AV1 does substantially more analysis per pixel than JPG or WebP, AVIF encoding is inherently slower — but that cost is invisible to end users once the image is cached on a CDN.
What about multi-page TIFF?
First page only. AVIF supports animation (AVIS), but Sharp's encoder produces still AVIF files. For multi-page archival content, extract each page first and convert individually.
Does transparency carry over?
Yes. AVIF supports a full 8-bit alpha channel (12-bit is also possible in the spec but Sharp emits 8-bit). RGBA TIFF input translates 1:1 without flattening.
What browsers decode AVIF?
Native support: Chrome and Edge (85+), Firefox (93+), Safari (16.1+ on macOS Ventura, iOS 16.4+). That's roughly 95% of global traffic as of 2025. For older-browser audiences, serve an AVIF source plus WebP and JPG fallbacks via <picture>.
