AVIF is built on the AV1 video codec and compresses photos far more efficiently than JPG. Converting your JPGs to AVIF can cut file sizes dramatically at the same visual quality — useful for speeding up websites, saving storage, or trimming what you upload.
This runs entirely in your browser. Your JPGs are re-encoded on your device and never uploaded, so it’s private and starts instantly.
How to convert JPG to AVIF
- Drop your .jpg files into the box above.
- Set the quality level.
- Download your AVIFs (or a ZIP of all of them).
Why convert JPG to AVIF?
The main reason is size. For most photographs, AVIF reaches the same perceived quality as JPG using a fraction of the bytes.
Faster-loading web pages and better Core Web Vitals.
Lower bandwidth and storage costs.
Smaller uploads where size limits are tight.
Choosing a quality level
The quality slider controls the trade-off between file size and detail. Around 60–75 is a good starting point for photos — it usually looks identical to the original while staying much smaller than the JPG. Push higher if you need maximum fidelity, lower if size matters most.
Because the JPG you start from is already lossy, converting to AVIF won’t recover lost detail — but it will store what’s there far more efficiently.
Will AVIF open everywhere?
AVIF is supported in all current major browsers (Chrome, Edge, Firefox, Safari) and most modern apps. Very old software may not read it yet — if you need a universal copy, keep a JPG too, or convert back with our AVIF to JPG tool.
Frequently asked questions

All current major browsers support AVIF. Very old browsers or apps may not.
Are my files uploaded?
No — conversion is done entirely in your browser.
How much smaller will the file be?
It depends on the image, but AVIF often produces files 30–50% smaller than JPG at comparable quality.
Can I batch convert?
Yes, convert several files at once and download them as a ZIP.
