Convert JPG to AVIF
Convert JPG to AVIF free in your browser: upload a .jpg file above and download it as .avif in seconds. No signup, no watermarks. A little, yes — AVIF is a lossy format, so the encoder discards data it considers invisible. At typical quality settings the difference is imperceptible for photos. If you plan to edit the image further, keep a copy of the JPG original.
Upload a .jpg file and download it as .avif in seconds. JPG is universal format for photographs, while AVIF is next-generation format with superior compression — below you can see exactly what changes in the conversion and whether switching makes sense for your image.

Should You Convert JPG to AVIF?
Conversion changes how your image is stored, not what it shows. Switching from JPG to AVIF trades one set of strengths for another, so it helps to know which side of that trade you are on.
Good reasons to switch
- ✓Best compression ratio
- ✓HDR support
- ✓Supports transparency
- ✓You need the file in a program or platform that only accepts .avif
Better off staying with JPG
- ✗Universal support — conversion does not remove this trade-off
- ✗Good compression for photos — conversion does not remove this trade-off
- ✗Fast encoding — conversion does not remove this trade-off
- ✗Nothing about your current workflow requires .avif
What Changes When You Convert
Quality
Both formats support lossy compression, so quality depends on the settings used. A high-quality AVIF export is visually indistinguishable from the JPG original for almost all content.
Transparency
JPG cannot store transparency, so there is nothing to preserve here — but if you later need a transparent version, convert from your original rather than from this AVIF copy.
Animation
The output is a still image. To animate it you would need dedicated frames or an animated source.
File size
Expect a meaningful size drop: AVIF files are typically around 50% smaller than JPEG at the same quality.

How the Converter Works
- Upload — drop your .jpg file into the tool above. It is processed temporarily and never shared.
- Convert — the file is re-encoded as .avif with sensible default quality settings.
- Download — grab the finished .avif file. Nothing is stored after processing.
