About This Tool
AVIF is the latest next-generation image format that delivers dramatically smaller file sizes than JPEG, PNG, and even WebP while maintaining superior visual quality. Developed by the Alliance for Open Media, AVIF typically achieves 50% smaller files than JPEG at the same perceived quality level, making it the most efficient image format available for web use today. Our free online AVIF converter lets you transform your existing images into AVIF format instantly, helping you take advantage of this cutting-edge compression technology without installing any software.
The tool is essential for web developers and performance-conscious site owners who want to stay ahead of the curve in image optimization. As browser support for AVIF continues to grow rapidly — it is now supported in Chrome, Firefox, Safari, and Edge — adopting AVIF early can give your website a significant speed advantage over competitors still using older formats. The converter also supports decoding AVIF files back to JPEG or PNG, so you can work with AVIF images you have received or downloaded.
All conversion processing runs entirely in your browser using advanced WebAssembly and canvas technology. Your images never leave your device, ensuring complete privacy and security. The tool gives you control over the compression quality so you can find the perfect balance between file size reduction and visual fidelity, and it supports batch conversion for processing entire image libraries at once.
How to Use This Tool
Upload Your Images
Drag and drop your images onto the tool or click to browse. You can upload JPEG, PNG, WebP, or AVIF files. Multiple files can be selected for batch conversion.
Choose the Conversion Direction
Select AVIF as the output format to compress your images, or choose JPEG/PNG if you are converting an existing AVIF file back to a widely compatible format.
Adjust the Quality Setting
Use the quality slider to control the compression level. AVIF maintains excellent quality even at low settings. A quality value of 60-70% typically produces results visually identical to the original at a fraction of the file size.
Convert and Download
Click the convert button to process your images. Download individual files or all converted images as a ZIP archive. The tool displays the original and converted file sizes so you can see the savings.
Advantages & Use Cases
Smallest File Sizes
AVIF delivers up to 50% smaller files than JPEG and 20% smaller than WebP at equivalent quality, dramatically improving page load speeds.
Superior Visual Quality
AVIF produces fewer compression artifacts than JPEG and WebP, resulting in cleaner images with better detail preservation at low bitrates.
Future-Proof Format
Backed by the Alliance for Open Media and supported by all major browsers, AVIF is positioned as the next standard for web images.
Browser-Based Privacy
All conversion runs locally in your browser. No files are uploaded to servers, making it safe for sensitive and proprietary images.
Batch Conversion Support
Convert entire image libraries to AVIF in one operation and download the results as a ZIP file, saving hours of manual work.
Supported Formats & Recommendations
The AVIF converter supports JPEG, PNG, WebP, GIF, and BMP as input formats, and can encode them to AVIF. It also supports decoding AVIF files back to JPEG, PNG, or WebP for compatibility purposes. AVIF supports both lossy and lossless compression, transparency (alpha channel), and animation. For web deployment, a quality setting of 60-70% produces excellent results with massive file size reductions. Use the HTML picture element with AVIF as the preferred source and JPEG or WebP as a fallback to ensure compatibility with all visitors.
