AVIF (AV1 Image File Format) uses lossy or lossless encoding and is best for next-gen web images — royalty-free format with better compression than WebP and JPEG. WebP (Web Picture Format) uses lossy or lossless encoding and excels at modern websites — Google-recommended format with superior compression for faster page loads. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
A small share of older browsers and apps reject AVIF while accepting WebP. Converting keeps one modern pipeline with a compatibility fallback — ~20% larger files, universal rendering.
WebP at quality 85 preserves AVIF look for photos; quality 75 halves bytes for thumbnails. Batch once per use-case rather than re-converting.
Yes — archive AVIF originals and serve WebP derivatives. Re-converting WebP back to AVIF later cannot recover the ~20% efficiency gap.
No — everything runs locally in your browser on Canvas. Only the WebP save touches the network — downloads are unlimited.

Bulk Image Format Converter
Convert image batches between JPG, PNG, WebP, and AVIF outputs (JPEG/PNG/WebP/AVIF/HEIC/HEIF/GIF/BMP/ICO/SVG inputs; HEIC via heic2any, SVG rasterized at intrinsic size or 1024px fallback) with a quality slider (10–100, default 80).

Batch Image Converter
Convert a batch of images to one output — JPG, PNG, or WebP — at quality 10–100% (default 80%), capped at 4096px longest side, then download everything as a ZIP. Files that fail conversion fall back to their originals inside the same archive — local library work.
