TIFF to AVIF Converter

How to Convert TIFF to AVIF Online

1. Upload Your TIFF Files: Drag and drop or click "Add Files" to select TIFF / TIF files. Print-archive scans, prepress masters, photographic plates, microscopy captures, and multi-page TIFFs all load. Batch is supported — drop in an entire folder of archive scans.
2. Pick an Image Quality Preset: Choose Highest or Very High for hero images and gallery masters, High (the typical default) for general web use, Medium for thumbnails and CMS listing pages, Low / Very Low for lazy-loaded grids, or Lowest for placeholder / blur-up images. Toggle Lossless (Yes / No) for pixel-perfect archival output, or set a target file size by percentage / exact KB-MB instead of a quality slider.
3. Resize, Set DPI, Tune Encoder (Optional): Pick a Resolution Preset (144P, 360P, 480P, 720P, 1080P, 1440P, 2160P / 4K, 4320P / 8K), scale by percentage, or set custom width × height in pixels. Adjust DPI from 72 / 96 (screen) up to 300 / 600 / 1200 (print). Tune Image Compression Level (1-10, higher = smaller file) and Compression Speed (1-10, lower = slower but tighter encode) when squeezing CDN bytes matters. Set Bit Depth (8 or 16-bit) for HDR-class TIFFs.
4. Convert and Download: Click Convert. Files encode in your browser session and download individually or as a ZIP — no sign-up, no watermark, no upload to a third-party server.

Why Convert TIFF to AVIF?

TIFF is the format scanners, prepress shops, and archives have shipped since 1986 — typically uncompressed or LZW, often 10-50 MB per page, frequently 16-bit per channel, and almost never directly viewable in a browser. AVIF (AV1 Image File Format) is the modern web's most efficient still format, using the same AV1 intra-frame codec that powers Netflix and YouTube AV1 streams. Converting TIFF to AVIF is the standard move for "I have a high-quality archival master and I need a small web copy that still looks great." Common reasons people convert TIFF → AVIF:

• Putting print-archive scans on the web — Museum digitization projects, library special collections, magazine back-catalog conversions, and law-firm e-discovery galleries all sit on TIFF masters. A 30 MB 600-DPI archival TIFF compresses to roughly 100-300 KB AVIF at the High preset while remaining sharp on a Retina display.
• Core Web Vitals on image-heavy sites — Photography portfolios, real-estate listings, and product catalogs that previously served TIFF (or massive JPEG exports of TIFF) cut Largest Contentful Paint dramatically. AVIF is typically 50% smaller than JPEG and 20-40% smaller than WebP at matched perceptual quality.
• HDR and 16-bit color from professional captures — Medium-format cameras, drum scanners, and microscopy rigs produce 16-bit TIFF. JPEG loses 8 bits of precision; AVIF keeps 10 / 12-bit color and the wide gamut (P3 / Rec.2020) intact for visual fidelity on modern displays.
• CDN egress and storage cost reduction — Bulk-converting a 200,000-image TIFF archive to AVIF at the High preset typically reduces total bytes by 95-99%, which directly translates to lower storage and lower per-request bandwidth charges across CloudFront, Cloudflare, or Fastly.
• Mobile and 4G visitors — TIFF doesn't render in any mobile browser without a plugin. AVIF decodes natively in Chrome 85+, Firefox 93+, Safari 16+ / iOS 16+, and Edge 121+ — covering roughly 96% of global sessions in 2026.
• Multi-page TIFF flattened to per-page AVIF — Scanned legal documents and old fax archives often live as multi-page TIFF. Splitting and re-encoding each page to AVIF keeps them indexable and previewable in modern document viewers.

If you need broader legacy compatibility instead of maximum compression, TIFF to JPG hits every email client and CMS. For a lossless web format with universal support, TIFF to PNG is the safer pick.

Frequently Asked Questions

How much smaller will my AVIF be than the TIFF?

A typical 300-DPI 8 × 10 inch archival TIFF lands around 25-50 MB uncompressed (or ~12-25 MB LZW-compressed). The same image at the High AVIF preset usually lands around 60-200 KB — a 99%+ reduction in bytes for a web-ready copy that still looks crisp on a Retina display. The actual ratio depends on source content (photographic vs flat / line-art) and the chosen quality preset.

Will I lose quality going from TIFF to AVIF?

Only if you pick a lossy preset. Toggle Lossless to Yes to get a pixel-perfect AVIF — the compression is mathematically reversible. Even at the High preset (the typical default), the visual difference is hard to spot at 1× zoom on a normal display. For archival masters, keep the source TIFF and treat the AVIF as a derivative web copy.

Does the AVIF preserve TIFF transparency?

Yes — TIFF's alpha channel maps to AVIF's alpha channel. AVIF carries 8-bit alpha by default and supports 12-bit alpha for high-precision masking. Transparent backgrounds, layered exports, and cutouts survive the conversion intact.

My TIFF is CMYK — what happens?

AVIF is RGB-only (no CMYK support in the format itself). If your source TIFF is a CMYK prepress file, the converter renders to sRGB on output, which is correct for web display. Keep the original CMYK TIFF as your print master; the AVIF is the web derivative. For preserving CMYK end-to-end, you'd stay in TIFF or use PDF/X.

Will AVIF preserve 16-bit color depth from my scanner?

Yes. AVIF supports 10-bit and 12-bit per channel. A 16-bit TIFF from a Hasselblad, Phase One, or drum scanner won't quite have its full precision retained, but 10/12-bit AVIF preserves far more dynamic range than 8-bit JPEG. For HDR display targets (P3 phones, Rec.2020 panels), AVIF is the right output format.

What about multi-page TIFFs — scanned books, legal archives?

AVIF is one image per file by design, so a multi-page TIFF outputs as a sequence of AVIFs (page-1.avif, page-2.avif, …) bundled into a ZIP. Each page becomes independently servable on the web and indexable in document viewers. If you'd rather keep pages bundled, TIFF to PDF preserves the multi-page structure.

Will my AVIF actually display in browsers and CMSes?

Yes, in roughly 96% of global browser sessions as of 2026: Chrome 85+ (August 2020), Firefox 93+ (October 2021), Safari 16+ / iOS 16+ (September 2022), Edge 121+ (January 2024). WordPress, Ghost, Sanity, Contentful, and Cloudinary all accept AVIF since 2023. For the remaining ~4% (older Safari, some Samsung Internet builds), serve a JPEG fallback via <picture><source type="image/avif">...</picture>.

Why is encoding slower than TIFF → JPEG?

AV1 intra-frame encoding does substantially more work than JPEG's DCT — that's where the 50% size advantage comes from. Lower the Compression Speed value (1-10) for tighter / slower encodes, raise it for faster but slightly larger output. Batch jobs of large archival TIFFs run noticeably longer than the JPEG equivalent; the trade is worth it for files served to thousands of visitors.

Can I convert AVIF back to TIFF?

Yes — see AVIF to TIFF for the reverse direction. Useful when bringing modern web captures into a print or archival workflow, though you can't recreate detail that lossy AVIF discarded — start from the original TIFF master if you still have it.
