TIFF to AVIF Converter

How to Convert TIFF to AVIF Online

1. Upload Your TIFF File: Drag and drop or click "+ Add Files" to select one or many .tif/.tiff images from your computer. Batch conversion is supported, so you can queue a whole scan folder or photo set at once.
2. Pick a Quality Preset: Default is Very High (Recommended) — visually lossless at roughly 70-80% JPEG-equivalent quality. Drop to High or Medium for smaller files, Lowest for thumbnails, or switch to Specific file size to target an exact KB/MB budget and let the encoder dial quality down to fit.
3. Resize and Choose Resolution (Optional): Use Keep original to preserve every pixel from the TIFF, pick a Preset Resolution (4320p down to 144p), enter a custom Width × Height in pixels, or scale by Resolution Percentage. Aspect ratio is locked when you only set width or height.
4. Convert and Download: Click Convert. Files process server-side and are deleted on a short retention window — no watermark, no sign-up, no per-file count cap.

Why Convert TIFF to AVIF?

TIFF is the workhorse of scanning, printing, and archival photography because it stores every pixel losslessly (often uncompressed or with LZW/Deflate) and supports up to 16-bit per channel color. The cost is file size — a 24-megapixel uncompressed TIFF can exceed 140 MB, which is unworkable for the web. AVIF, the AV1-based image format finalized in 2019, gives you a modern container that holds 8/10/12-bit color, HDR, wide color gamut, and alpha transparency while cutting bytes by roughly half compared to JPEG at matching quality (and far more compared to TIFF). It is now supported by Chrome 85+, Firefox 93+, Safari 16.4+, and Edge 121+, putting global browser support above 94% as of 2026.

• Web delivery of archival photos — Museums, libraries, and stock-photo workflows often master in TIFF and need a small, modern web derivative. AVIF preserves 10-bit color and HDR metadata in a fraction of the bytes, so a 100 MB scan can land under 1 MB online without visible degradation.
• Real estate and product photography — Cameras like the Phase One IQ4 and high-end Hasselblads still output 16-bit TIFFs for retouching. Converting the final retouched file to AVIF speeds up listing pages and product galleries without sacrificing the color depth that makes fabric textures and wood grain pop.
• Print-to-screen pipelines — Designers receive layered TIFFs from print agencies and need a screen-friendly preview to share with clients. AVIF beats JPEG on banding in skies and skin gradients because of its 10-bit channels.
• HDR photo sharing — TIFF can hold HDR but few viewers render it correctly. AVIF carries HLG/PQ Rec. 2020 metadata and is natively decoded by modern Chrome/Safari, so HDR shots actually display in HDR on supported displays.
• Storage and CDN cost reduction — A 5,000-image catalog of 50 MB TIFFs takes 250 GB. Re-encoded as Very-High-quality AVIF, the same set typically lands under 5 GB, which slashes object-storage bills and origin-fetch latency.
• Drop-in replacement for JPEG/PNG on the web — AVIF supports alpha transparency, so a TIFF with a clipped product on transparent background converts to AVIF without falling back to PNG's larger file size.

Frequently Asked Questions

How much smaller will my AVIF be compared to the source TIFF?

For typical photographic content the AVIF is usually 30-100× smaller than an uncompressed TIFF and roughly 5-20× smaller than an LZW-compressed TIFF. A 24 MP RGB photo that lands around 140 MB uncompressed TIFF will typically encode to 0.8-2 MB at the Very High preset. Synthetic content (line art, screenshots) compresses even more aggressively because AV1 handles flat regions extremely well.

Will I lose the 16-bit color depth from my TIFF?

AVIF tops out at 12 bits per channel, so a 16-bit TIFF will be rounded to 12-bit (or 10-bit depending on encoder choices). For viewing this is imperceptible — 12-bit per channel is more than four times the precision of 8-bit JPEG and well beyond what any current consumer display can show. For further editing keep the TIFF master; for distribution AVIF preserves smoother gradients than 8-bit JPEG.

Does AVIF support transparency like my TIFF alpha channel?

Yes. AVIF carries an 8-bit alpha channel, so a TIFF with a knocked-out background (transparent PNG export from Photoshop, then saved as TIFF) keeps its transparency through conversion. This is one of AVIF's main advantages over JPEG, which has no alpha.

What about HDR — will my Rec. 2020 / HLG TIFF still look HDR?

AVIF natively encodes HDR with HLG, PQ, and Rec. 2020 primaries. If your TIFF stores HDR metadata that the source application wrote (Photoshop, Capture One, Lightroom Classic 13+), the AVIF preserves those primaries and modern Chrome/Safari on HDR displays will tone-map them correctly. Most plain sRGB TIFFs do not carry HDR data, so converting them yields an SDR AVIF.

Can every browser open my AVIF after conversion?

AVIF works in Chrome 85+ (Aug 2020), Firefox 93+ (Oct 2021), Safari 16.4+ (March 2023), Edge 121+ (Jan 2024), and Opera 71+. That covers about 94% of global browser sessions in 2026. The notable gap is legacy Internet Explorer and very old Safari/iOS (< 16). For those audiences serve a <picture> element with a JPEG or WebP fallback.

Should I use the Quality Preset or the Specific File Size option?

Use Quality Preset when consistency of visual quality matters more than predictable file size — every image lands at the same perceptual quality but bytes vary with content. Use Specific File Size when you have a hard byte budget (an ad-network limit of 200 KB, a CMS upload cap, an email attachment ceiling). The encoder will reduce quality just enough to fit.

Why is multi-page TIFF only producing one AVIF?

Standard AVIF treats each image as a single still. If your source is a multi-page TIFF (e.g., a scanned multi-page document), we extract the first page by default. To convert all pages, split the TIFF into individual files first or use a PDF workflow — converting the multi-page TIFF to PDF and then to per-page images keeps the original order.

Does AVIF compress better than WebP or JPEG XL?

Against JPEG at matched quality, the Alliance for Open Media and independent studies typically measure AVIF at 30-50% smaller for the same VMAF/SSIM. Against WebP it is usually 15-25% smaller on photographic content. JPEG XL achieves similar or slightly better ratios on lossless and high-fidelity content, but browser support is far narrower in 2026 — Safari ships JPEG XL, Chrome and Firefox do not. AVIF is the safest universally supported "next-gen" choice today.

Are my files private?

Yes. Uploads are processed for conversion only, deleted on a short retention window, and never indexed or shared. We do not sign you up, watermark output, or store the source TIFF beyond what is needed to deliver your AVIF.
