Why Convert TIFF to AVIF?
TIFF to AVIF conversion preserves lossless quality while achieving exceptional compression compared to TIFF's large file sizes. Converting professional TIFF images to AVIF enables efficient web use while maintaining the quality standards required by photographers and designers.

TIFF to AVIF on Every Platform
Web Developers
Use the <picture> element with AVIF as the primary source and TIFF as fallback: <picture><source srcset="image.avif" type="image/avif"><img src="image.tiff"></picture>. This serves AVIF to modern browsers while maintaining backward compatibility.
WordPress Sites
WordPress 5.8+ supports WebP uploads natively. For AVIF, use plugins like ShortPixel or Imagify that auto-convert uploaded images. Converting your existing TIFF library to AVIF can reduce your site's total image weight by 30-50%.
Professional Workflows
If you are working in Adobe Photoshop, Lightroom, or Capture One, consider exporting directly to AVIF from those applications for maximum control over quality settings. Use PhotoFormatLab for quick batch conversions when you do not need fine-grained export controls.
Batch Conversion
PhotoFormatLab processes all files in your browser using Web Workers for parallel conversion. You can convert hundreds of TIFF files to AVIF simultaneously — the speed depends on your device's CPU, not your internet connection.
Common Issues and Solutions
The converted AVIF file looks slightly blurry or has artifacts
AVIF uses lossy compression. Try increasing the quality slider to 95% or higher. At quality 90%+, the difference from the original is virtually imperceptible for most images.
Conversion is very slow on my device
Large files (over 20 MB) require significant CPU processing since conversion happens entirely in your browser. Close other browser tabs to free up memory, or try converting fewer files at a time. On mobile devices, the process is naturally slower than on desktop computers.
The output file is much larger than expected
This typically happens when converting from a highly compressed format (like TIFF) to a less compressed one (like AVIF). The output reflects the actual image data, not the compression efficiency of the source. Try lowering the quality setting to reduce file size.
Frequently Asked Questions
AVIF is supported by Chrome, Firefox, Opera, and Edge. Safari added AVIF support in version 16.4 (March 2023). For maximum compatibility, use the HTML <picture> element to serve AVIF with a JPG or WebP fallback for older browsers.
For most purposes, 85-90% quality provides an excellent balance between file size and visual quality. Use 95%+ for photographs where quality is critical (portfolios, print). Use 70-80% for web thumbnails or previews where smaller size matters more. Our converter defaults to 90%.
No. PhotoFormatLab converts files entirely in your browser using JavaScript, Canvas API, and WebAssembly. Your images never leave your device — no upload, no server processing, no cloud storage. This makes the conversion completely private and works even without an internet connection after the page loads.
There is no artificial limit. You can convert hundreds of files in a single batch. The practical limit depends on your device's available memory and CPU speed. For very large batches (500+ files), we recommend processing in groups of 50-100 for optimal performance.
Most individual files convert in under 2 seconds on a modern device. A batch of 50 files typically completes in 30-60 seconds. Since processing happens on your device, conversion speed depends on your hardware — desktop computers are generally faster than phones. There is no upload or download wait time.
