About TIFF → AVIF conversion

For publishing high-resolution scans or print masters online, AVIF is the most efficient modern destination. Converting TIFF to AVIF can reduce file sizes by 95% or more while keeping the perceptual quality your audience expects from a print-grade source.

Tagged Image File Format (TIFF) was created by Aldus in 1986 and now maintained by Adobe. TIFF is the workhorse format of professional print, publishing, scanning, and archiving. It supports lossless compression, multiple layers, alpha channels, CMYK color, 16- and 32-bit depth, and even multi-page documents — but that flexibility means the spec is huge and many viewers only handle a subset. You will most often encounter TIFF files as high-resolution scans from flatbed and document scanners, master files from print and publishing pipelines, medical, scientific, and GIS imagery requiring lossless precision.

Web browsers and mobile galleries do not display TIFFs at all, email clients reject them as attachments, and most consumer photo editors handle only the simplest TIFF variants — leaving multi-page or 16-bit files unreadable. That is the friction this converter removes — by producing a clean AVIF you can drop into any AVIF workflow without surprises.

AVIF is the AV1-based image format standardized in 2019. AVIF achieves up to 50% smaller files than JPG at the same visual quality and is supported natively in Chrome, Firefox, Safari, and Edge — covering over 90% of global web traffic. It is the obvious destination when your goal is high-traffic websites and image optimization at scale.

Multi-page TIFFs convert the first page by default; for screen and web use, dropping the bit-depth to 8-bit during conversion gives dramatically smaller files with no visible difference. Use AVIF for production web delivery where bandwidth and Core Web Vitals matter most. Converter.Plus handles the entire TIFF→AVIF pipeline locally in your browser using modern WebAssembly and Canvas APIs — your files never leave your device, there is no signup, no watermark, and no per-file size cap. Drop a single image or a whole batch and grab the results as individual downloads or a single ZIP.
