Free, browser-based, no upload required
Convert TIFF and TIF images to AVIF directly in your browser. The smallest widely supported format for photographic content, ideal for large scanned photos and camera TIFF exports headed for the web.
TIFF to AVIF
Smallest modern format
Around 50% smaller
Than equivalent JPEG
No uploads
Files stay on your device
Drop TIFF files here or click to browse
Supports .tif and .tiff, all processing stays in your browser
AVIF encoding is slower than JPEG or WebP. Large files or batches may take a little longer to finish, entirely in your browser.
AVIF is the right choice when file size matters most and the destination supports modern formats.
Large photographic scans
Scanned photo TIFF files are often uncompressed and very large. AVIF gives the biggest practical reduction for photographic detail.
Professional camera exports
Camera TIFF previews converted to AVIF keep visual quality high at a fraction of the file size for web galleries.
Maximizing page speed
Replacing large TIFF or JPEG files with AVIF reduces page weight more than most other widely available format choices.
Image archives for the web
Publishing a large TIFF archive online becomes far more practical once each file is converted to AVIF.

AVIF is the most efficient widely supported format for photographic content, typically producing files around 50 percent smaller than an equivalent JPEG and noticeably smaller than WebP at the same visual quality. For TIFF images that are large photographic scans or camera exports headed for the web, AVIF gives the smallest practical file size while keeping detail intact.
Yes. AVIF support is now near universal across Chrome, Firefox, Safari and Edge, and Google's PageSpeed Insights recommends it as a preferred format for web images. For situations needing guaranteed compatibility with very old browsers or software that has not been updated, WebP or JPEG remain safer fallback choices, but AVIF is the strongest default for most modern audiences.
Yes, AVIF encoding is more computationally intensive and can take noticeably longer than JPEG or WebP, especially for large TIFF source files. This happens entirely in your browser using WebAssembly, so there is no upload wait, only the local encoding time itself, which scales with image size and the number of files being converted.
No. The TIFF decoder and AVIF encoder both run entirely in your browser using WebAssembly. Your file never leaves your device at any point during the conversion.
