How to use Convert JPG to AV1
- 1. Add the JPG to shrink. Drop in the photo you want re-encoded using AV1's image format, AVIF, which typically compresses far more efficiently than JPEG.
- 2. Set the AVIF quality. Drag AVIF quality (%) to balance file size against visible detail. AVIF often looks comparable to JPEG at a noticeably smaller file size for the same quality setting.
- 3. Download the AVIF file. The tool re-encodes the photo using AV1 image compression and produces photo.avif. Download it for use on websites or in apps that support the modern AVIF format.
When to use Convert JPG to AV1
Convert JPG to AV1 re-encodes a photo as an AVIF file, which uses AV1's modern compression to typically produce far smaller files than JPEG at similar visual quality. It is aimed at anyone optimizing images for faster page loads on platforms that support the newer format.
- Shrinking website images for faster page loads. A site's photos are the biggest contributor to page weight and slow load times. Converting them to AVIF at quality 50 usually cuts file size substantially while keeping the images sharp.
- Reducing bandwidth costs for image-heavy content. A photo-driven app pays for bandwidth on every image served. Switching to AVIF for supported browsers meaningfully lowers total data transferred without a visible quality drop.
- Testing AVIF savings against your current JPEG assets. You want concrete numbers on how much smaller AVIF would make your existing photo library before committing to a format migration. Converting a sample lets you compare file sizes directly.
- Serving modern formats to capable browsers. You want to offer AVIF to browsers that support it while keeping JPEG as a fallback. Converting your source photos gives you the AVIF version needed for that responsive image setup.
Examples
