Convert JPG to AVIF
AVIF can reduce delivery size for modern web images. Because the JPEG source is already lossy, use a moderate AVIF quality and compare the generated size instead of expecting conversion to restore detail.
JPG to AVIF
Create compact AVIF copies of JPEG photos. This route opens the shared Image Studio with a focused preset.
Output
WebP is a practical default for most images.
This tool always converts to AVIF.
Why this format?
Choose the color for transparent areas.
Compression
A practical quality and file-size balance at the original dimensions.
Process
Process the selected images.

How it works
Three steps, entirely on your device
- 1
Choose a JPG or JPEG photo.
- 2
Set AVIF quality and optional resize controls.
- 3
Convert sequentially and download the AVIF result.
Privacy and support
The JPEG stays on your device. The AVIF encoder is self-hosted and loaded only after processing is requested.
Supported formats
JPEG input and AVIF output, including quality changes and orientation-aware decode, are browser-tested.
Limitations
- Encoding may take several seconds on slower devices.
- Conversion cannot improve source JPEG detail.
- Metadata is omitted from the new AVIF.
FAQ
Frequently asked questions
What AVIF quality should I use?
Start near 70–80 and compare the result. Texture-heavy photos may benefit from a higher value.
Why is AVIF slower?
The WebAssembly encoder performs more complex compression than the browser-native JPEG path.
Will EXIF orientation be applied?
The source is decoded orientation-aware before pixels are encoded into the new file.
