TIFF to AVIF Converter
Processing entirely on your device — large files may take a moment.
TIFF Image and AVIF Image exist for different jobs: TIFF is the standard format of the scanner, fax and print industries. It stores very high quality — usually lossless — and can hold multiple pages in one file, at the cost of large file sizes. AVIF delivers the smallest files at top visual quality for modern websites — it is supported by all current browsers.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

Frequently asked questions
Is this TIFF to AVIF converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Will converting TIFF to AVIF reduce quality?
AVIF uses lossy compression, so a small amount of recompression is unavoidable. The quality slider lets you choose between maximum fidelity and smallest file size — the default is visually indistinguishable for photos.
