GIF to AVIF converter

GIF is limited to 256 colors and uses legacy LZW compression from 1987. AVIF (AV1 Image File Format) is a next-generation format based on the AV1 video codec, offering dramatically better compression: AVIF files are typically 50–70% smaller than equivalent GIFs while supporting millions of colors, alpha transparency, and HDR.

AVIF is supported in Chrome 85+, Firefox 93+, Safari 16.4+, and Edge 121+. Browser support continues to expand rapidly. For maximum compatibility with older browsers, consider WebP as an alternative.

Converting GIF to AVIF is ideal for web optimization: smaller files mean faster page loads and lower bandwidth costs. AVIF preserves transparency from the original GIF and removes the 256-color limitation, producing higher-quality results.

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 GIF 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.

• Start with quality 85 – this is typically the sweet spot for AVIF compression, offering significant file size reduction with minimal visible quality loss.
• Batch convert for efficiency – if you have many GIF files, use the batch conversion feature to process them all at once. This saves considerable time compared to one-by-one conversion.
• Compare before downloading – use the live preview to compare the original GIF with the AVIF result. Adjust quality settings until you find the right balance for your specific use case.
• Keep your originals – always save a copy of your original GIF files. Lossy compression is irreversible, so having the originals allows you to re-convert with different settings later.

The quality slider lets you set a value from 60% to 95%. Higher values mean better image quality but larger file sizes.

• 80% (default) – a good balance for most use cases. GIF’s 256 colors are preserved fully at this setting, and the AVIF file will be dramatically smaller.
• 85–90% – for graphics where you want maximum sharpness, e.g. detailed icons or diagrams.
• 60–70% – when minimizing file size is the priority, e.g. thumbnails in category grids.

Since GIF is limited to 256 colors, even lower AVIF quality settings produce excellent results. The visual difference is minimal while the file size reduction is substantial.

Savings depend on image complexity and the original GIF’s color usage. Below are example results:
