JPG / PNG / WebP to AVIF Bulk Converter
Switch to single file (server side) converter »Bulk converter works differently than the rest of the converters on this website. All files are processed in your browser and no data is sent to our servers. It's faster and more private (the files never leave your computer), but you won't be given links to the rest of the editing tools, so if you want to resize, crop, rotate or do anything other to the images, you'll need to upload them to the relevant tools.

Batch Convert JPG, PNG, and WebP Images to AVIF - Client-Side Privacy Tool
Bulk convert your JPG, PNG, and WebP images to the modern AVIF format entirely in your browser. AVIF provides superior compression efficiency compared to JPEG and PNG, allowing you to significantly reduce file sizes (often by 50% or more) without sacrificing visual quality - ideal for optimizing website assets, reducing storage costs, and improving page load speeds.
All conversion happens locally via JavaScript - your photos never leave your computer and are never uploaded to any server, ensuring complete privacy. There are no file size limits or upload waiting times.
Drag and drop your image files, set the desired AVIF quality level, and convert them all at once. Download optimized AVIF files individually or as a ZIP archive, ready for use on your website or app.
