Why convert JPG to AVIF?
AVIF is based on the AV1 video codec and is the most efficient mainstream image format available today. For typical photographic content, AVIF at quality 60 produces a file roughly 50% smaller than the equivalent JPG with no visible quality loss. Browser support reached the 95% threshold in 2025 (Chrome 85+, Firefox 93+, Safari 16.4+, Edge). If your audience uses evergreen browsers, AVIF is safe to ship as the primary image format with a JPG fallback inside <picture>. Tiny Pixel Kit converts JPG to AVIF inside your browser, which makes encoding speed depend on your device — AVIF is roughly 5–10× slower to encode than JPG, so expect a small wait on older hardware. The output is downloaded directly; no file is uploaded.
Where does this pay off most? Hero images and above-the-fold visuals on landing pages are the big-ticket items: cutting a 700 KB JPG hero to a 320 KB AVIF removes nearly 400 KB from your LCP critical path. Product thumbnails in a long grid benefit too, because the savings compound — a category page with 60 thumbnails saves 20+ MB of bandwidth per visitor. The trade-off is encoding time at build, which is fine for one-off hero images but adds up for huge catalogs. For batch work, Tiny Pixel Kit's browser-side processing keeps you off a server-side queue and avoids per-image costs.
