Why ToFormat?
Up to 50% Smaller Files
AVIF delivers dramatically better compression than JPG. A 10 MB TIFF photo can shrink to 300‑500 KB in AVIF while looking virtually identical.
Preserve Quality
Our encoder extracts the full detail from your TIFF file and re‑encodes it to AVIF with minimal loss. Fine‑tune the quality slider to match your needs.
Batch Conversion
Upload up to 20 TIFF images at once. We process them simultaneously and package them in a ZIP for one‑click download.
About the Formats
📄 What is TIFF?
TIFF (Tagged Image File Format) is a flexible, lossless format created in the 1980s. It supports multiple layers, pages, various color depths, and compression options. It is the standard for printing, scanning, and digital archiving, but files are very large.
All TIFF conversion tools →🚀 What is AVIF?
AVIF (AV1 Image File Format) is a next‑generation format based on the AV1 video codec. Created by the Alliance for Open Media — Google, Apple, Mozilla, Netflix — it compresses up to 50% better than JPG and 20‑30% better than WebP, with support for transparency, HDR, and wide color gamut.
All AVIF conversion tools →How to Convert
Upload your TIFF
Click the upload area or drag and drop your TIFF files. You can select up to 20 at once. Multi‑page TIFFs become multiple AVIFs.
Adjust quality
Move the quality slider to balance file size and detail. The default 80% is optimal for most photos. Choose lossless for pixel‑perfect output.
Download AVIF
Your compressed AVIF files are ready. Download within 10 minutes before they're automatically deleted.
When to Convert TIFF to AVIF
🌐 Website Performance
AVIF is the top format for Core Web Vitals. Replacing TIFF with AVIF cuts image payload by 90%+, directly improving LCP and page speed.
💡 Wider support: try TIFF to WebP →📱 Mobile & Cloud
Smaller images load faster on cellular networks and consume less cloud storage. AVIF is ideal for content-heavy mobile apps.
💡 Universal compatibility: TIFF to JPG →🖼️ Online Galleries
Display high‑resolution scans at a fraction of the file size. AVIF preserves subtle gradients and color transitions that JPG compression destroys.
💡 Lossless archival: TIFF to PNG →💾 Archive Access
Create lightweight AVIF access copies from your TIFF masters. Save space while keeping excellent quality for quick previews.

Need wider browser support? TIFF to WebP covers 97%+ browsers vs AVIF's 93%+. For pixel‑perfect lossless output, try TIFF to PNG.
💡 Pro Tips
- AVIF encoding is slower than JPG or WebP — but the 40‑50% size savings are worth every millisecond. Our servers use optimized effort level 4 for the best speed‑to‑quality ratio.
- Serve AVIF with a WebP or JPG fallback via the HTML
<picture>element for maximum browser reach. - TIFF often contains 16‑bit per channel data. We preserve high bit depth in AVIF (10/12‑bit) when you enable HDR mode.
- If your TIFF has multiple layers or pages, we convert each to a separate AVIF file. Perfect for multi‑page scans.
- For maximum metadata retention, enable EXIF preservation. We transfer camera settings, GPS, and ICC profiles from TIFF to AVIF.
- AVIF supports transparency. If your TIFF has an alpha channel, we preserve it in the AVIF output.
How TIFF to AVIF Conversion Works
AVIF is the largest leap in image compression since JPG debuted in 1992. It is built on the AV1 video codec — a royalty‑free, open standard developed by the Alliance for Open Media (Google, Apple, Mozilla, Netflix, and others).
When you convert TIFF to AVIF, our encoder decodes the TIFF data (which may be uncompressed, LZW, or ZIP compressed) and re-encodes the pixel data using AVIF's modern toolset: variable block sizes up to 64×64, intra-frame prediction, and context-adaptive binary arithmetic coding. The result is a file that is 90%+ smaller at the same perceived quality — or visually superior at the same byte count.
The process is fully server‑side and takes 1‑3 seconds per image. Your files are automatically deleted within 10 minutes. No software to install, no account required.
TIFF vs AVIF: Technical Comparison
TIFF compresses images with optional lossless methods (LZW, ZIP) but often remains huge. It supports 16‑bit color, layers, and pages, making it the archival gold standard. AVIF uses superblocks up to 64×64 pixels with recursive partitioning, intra prediction borrowed from video codecs, and advanced entropy coding. Independent studies by Netflix, Facebook, and others consistently show 40‑50% bitrate savings over JPG at equivalent SSIM scores.
AVIF also supports 10‑bit and 12‑bit color depth (over 1 billion colors), alpha transparency, HDR tone mapping, and both lossy and lossless modes — many of which TIFF also supports, but AVIF does so with far greater efficiency. For a detailed comparison with WebP, see our WebP tools page.
AVIF Browser & Platform Support (2025)
AVIF is supported in Chrome 85+, Firefox 93+, Safari 16.4+, Edge 121+, and Opera — over 93% of global browser traffic according to Can I Use. The remaining gap is primarily older iOS/iPadOS versions and legacy enterprise browsers.
For production websites the recommended pattern is to serve AVIF as the primary source inside a <picture> element, with a WebP middle layer (97% support) and a JPG fallback. Major CDNs — Cloudflare, Fastly, Imgix, AWS CloudFront — can automate this via Accept-header content negotiation, so you upload once and every visitor gets the optimal format.
Beyond the browser, AVIF is natively supported in Android 12+, Windows 11 Photos, GIMP 2.10+, and Adobe Photoshop 25+. Apple added AVIF support in Safari 16.4 and macOS Ventura. Explore all our AVIF conversion tools for more options.
