How it works
Add your JPG file
Drag a JPG file onto the drop zone, or click to browse. You can select several at once.
Choose your settings
Adjust the quality slider if you want a smaller file or a sharper result. 80 suits most photographs.
Download the AVIF
Conversion runs on your device as soon as each file is added — no upload, no queue. Download each result when it is ready.

Questions
Will converting JPG to AVIF make the file smaller?
Usually, yes. A 12-megapixel photo is around 3.2 MB as JPG and around 1.4 MB as AVIF — about 56% smaller. Because AVIF is lossless the result depends entirely on the image content — flat colour and text compress far better than photographic detail.
Does converting JPG to AVIF lose quality?
Slightly. Re-encoding one lossy format as another means a second round of compression, which can soften fine detail. In practice the loss is hard to see at high quality settings, and AVIF's newer codec often preserves detail better than the JPG original did. Keep quality at 80 or above and the difference will not be visible at normal viewing size.
Should I use AVIF or WebP?
AVIF files are typically 25–35% smaller than WebP at the same quality, which is a real win on image-heavy pages. The trade-offs are much slower encoding and a support floor of Safari 16.4 (March 2023), so a small share of visitors cannot see it. Serve AVIF with a WebP fallback via a <picture> element if you want both.

On a typical 12-megapixel phone photo, the AVIF output comes out about 56% smaller than the JPG original. These are order-of-magnitude figures for one kind of image — your own results will vary a great deal, because flat colour, text and line art behave nothing like photographic detail, and the quality slider moves the figure substantially.
What to watch out for
- Encoding is computationally expensive and noticeably slow
- Requires Safari 16.4+ (2023), so a small share of users still miss it
- Sparse support outside browsers — most desktop editors cannot open it
About the two formats
JPEG has been the default photo format for three decades, and its compatibility is unmatched — if a device can display an image at all, it can display a JPEG. The trade-offs are that it discards detail permanently on every save, and it has no transparency channel at all, so anything transparent becomes a solid background.
AVIF currently produces the smallest files of any widely supported format — commonly half the size of JPEG at the same perceived quality, with excellent handling of gradients and noise. The cost is encoding time, which can be seconds per image rather than milliseconds, and support that only became universal with Safari 16.4 in 2023.
Other conversions
Everything runs on your device — nothing is uploaded, so there is no size limit, no queue and no copy left on a server afterwards. There is more on how browser-based conversion works if you want the detail. Otherwise, browse every image tool, or convert AVIF back to JPG.
