Can I convert multiple TIFF files at once?

Yes — this tool supports batch conversion. Drop multiple TIFF files at once, monitor per-file status, then download individually or as a single timestamped ZIP archive.

Does my data get uploaded to a server?

Never. All TIFF decoding and AVIF encoding happens entirely in your browser using JavaScript and the Canvas API. Your files never leave your device.

What software opens AVIF files?

AVIF files open in Chrome, Edge, Firefox, Safari 16.4+, Windows 11 Photos, macOS Ventura Preview, GIMP 2.10.22+, and recent Photoshop versions with the AVIF codec plugin.

TIFF to AVIF Converter

Convert TIFF images to next-gen AVIF format locally in your browser. Batch convert, preview thumbnails, adjust quality, download individually or as a ZIP. No uploads, no account required.

⚠ Your browser may not support AVIF encoding. For best results use Chrome 85+, Edge 85+, or Firefox 93+. Safari users may need to update to macOS Ventura or later.

What This Tool Does

Converts TIFF and TIF images — common in photography, publishing, and scientific imaging — to AVIF format entirely in your browser. AVIF is the next-generation web image format built on the AV1 codec: it delivers dramatically smaller files than TIFF (and even JPG or WebP) with excellent visual quality. No server upload, no account, no file size limits imposed by a backend.

Who This Is For

Web developers publishing high-quality scans or photographs originally saved as TIFF
Photographers converting TIFF exports for web delivery — AVIF loads faster than JPG or WebP
Anyone who needs the smallest possible file size from TIFF originals without visible quality loss
Teams testing AVIF support in CDNs, browsers, and CMS platforms

Example: Input: scan.tiff (uncompressed A4 scan, 25 MB) → Output: scan.avif (often 0.5–2 MB at quality 85, visually identical on screen)

💡 Need lossless output instead? Keep your original TIFF as the master file. For broad browser compatibility, TIFF to SVG wraps your image in a universally supported container. Once you have an AVIF, Image Compressor can fine-tune it further if needed.

How It Works

Drop your TIFF filesDrag one or more .tiff or .tif files onto the drop zone, or click Browse Files. Thumbnails generate immediately using the UTIF.js decoder.

Set quality and click ConvertUTIF.js decodes each TIFF to raw pixel data; the browser's Canvas API then encodes it as AVIF at your chosen quality level using hardware acceleration where available.

Download your AVIFsDownload files individually or check "Download as ZIP" for a single timestamped archive. The tool resets automatically after export.

🔒 Privacy & Security

All decoding and encoding runs entirely in your browser. TIFF files are never sent to any server — they stay in your browser's memory from load to download. This is especially important for sensitive archival, medical, or client images.

Frequently Asked Questions

Does converting TIFF to AVIF reduce image quality?▼

AVIF uses lossy compression, but the AV1 codec is very efficient. At quality 85 (the default), visual degradation from your TIFF original is minimal and file sizes drop dramatically. For archival work, keep your TIFF master and only convert for web delivery.

Which browsers support AVIF?▼

Chrome 85+, Edge 85+, and Firefox 93+ support AVIF encoding via the Canvas API used by this tool. Safari added AVIF decode support in version 16.4 (macOS Ventura / iOS 16.4), though canvas encoding may vary. Use Chrome or Edge for guaranteed results.

What TIFF variants does this tool support?▼

The UTIF.js decoder handles uncompressed TIFFs, LZW-compressed TIFFs, and ZIP/Deflate-compressed TIFFs. RGB, grayscale, and CMYK color spaces are supported. Very exotic or proprietary TIFF sub-formats may not decode correctly — if a file fails, check the error badge for details.

What quality setting should I use?▼

Quality 85 (default) is ideal for most web images — excellent visual quality at a fraction of the original file size. Use 90–95 for near-lossless output where fine detail matters, or 70–84 for maximum compression when file size is critical.

Can I convert multiple files at once?▼

Yes — drop up to 25 or more files at once. The tool processes them in batches of two, shows per-file status badges, and lets you download all AVIFs individually or as a single timestamped ZIP.

What is the ZIP file named?▼

The ZIP is named dataconversioncenter_tiff_to_avif_YYYYMMDDHHMM.zip using your local time — for example dataconversioncenter_tiff_to_avif_202603061430.zip.
