Convert TIFF files to modern AVIF. Massive file size reduction. Runs entirely in your browser. No server uploads, no registration required.

TIFF is the standard for professional imaging — used in print production, medical imaging, and archival storage. However, TIFF files are extremely large and cannot be displayed in web browsers. AVIF (AV1 Image File Format) delivers exceptional compression: files are 60–80% smaller than TIFF while maintaining excellent visual quality.
AVIF supports millions of colors, alpha transparency, HDR content, and both lossy and lossless compression. It is supported in Chrome 85+, Firefox 93+, Safari 16.4+, and Edge 121+. Converting TIFF to AVIF is essential when preparing professional images for web publishing.
Note that AVIF uses lossy compression by default — some pixel-level detail may differ from the original TIFF. For archival purposes, keep the original TIFF. For web use, AVIF provides the best file-size-to-quality ratio available today.
All processing happens locally in your browser — nothing is sent to any server. No registration, no limits, no watermarks.
Businesses, developers, and creators worldwide rely on image format compatibility. Whether you are preparing product images for Amazon, eBay, Etsy, Shopify, optimizing graphics for WordPress, Wix, Squarespace, or converting photos for government portals worldwide, having the right format matters.
Modern web standards increasingly favor efficient formats. Google PageSpeed Insights and Core Web Vitals metrics reward pages that use optimized images. Converting TIFF to AVIF can directly improve your Largest Contentful Paint (LCP) score, which impacts both search rankings and user experience.
For email marketing campaigns and social media, AVIF provides excellent compression while maintaining visual quality. Whether you are a freelancer, small business owner, or enterprise user, this converter handles your image conversion needs reliably and securely.

The quality slider lets you set a value from 60% to 95%. Higher values mean better image quality but larger file sizes.
TIFF files are typically very large (20–50 MB). At 80% quality, AVIF reduces them to 200–500 KB with minimal visible quality loss — a 95%+ reduction in file size.
TIFF files are uncompressed or use lossless compression, making them extremely large. AVIF provides dramatic savings:
Camera photo (TIFF)
25 MB → 450 KB
Scanned document
15 MB → 180 KB
Product photo
8 MB → 250 KB
Actual savings vary depending on image content and quality settings. The converter shows the exact size before and after conversion for each file.
