Compress multiple images to AVIF in one batch
A bulk AVIF compressor makes it easier to convert many images to the AVIF format without processing every picture separately. Upload multiple JPG, PNG, WebP, GIF, BMP, TIFF or AVIF images, choose your preferred target size, and process the complete batch to AVIF in one workflow.
This free AVIF compression tool works directly in your browser. That means you can convert and compress photos and images without sending the original files to a remote server. AVIF is a modern format that can produce smaller files than JPEG or PNG at comparable visual quality, which is useful for websites, blogs, ecommerce product images and other digital assets.
Bulk
Process multiple images in one batch instead of converting files individually.
Target KB
Set a desired file-size target and let the browser optimize each selected image as AVIF.
Browser-Based
