How do I convert AVIF to JPG?

Add your AVIF file to the upload area above, then press Convert. The JPG file downloads straight to your device. You do not need an account, and there is no watermark.

Are my files uploaded to a server?

No. This conversion runs entirely inside your browser using WebAssembly, so the file never leaves your device — you can even disconnect from the internet after the page loads and it will still work.

Does converting to JPG reduce quality?

JPG uses lossy compression, so some data is discarded. At the default quality the difference is very hard to see or hear; raise the quality setting if you need to be certain, at the cost of a larger file.

How large a file can I convert?

Up to 120 MB per file for this conversion. Because the work happens in your browser, the practical limit is your device's memory — larger files work on a desktop with plenty of RAM and may fail on an older phone.

Can I convert several files at once?

Yes. Add as many as you like and press Convert All. Each file is processed independently, so one failure does not stop the rest, and you can download everything together as a ZIP.

Can I use this on my phone?

Yes. FileTools360 works in mobile browsers on iOS and Android, including choosing files straight from your camera roll. Very large videos may run out of memory on a phone — those are better converted on a laptop.

AVIF and JPG explained

AVIF stores still images using the AV1 video codec's intra-frame compression. It generally achieves the smallest files of any widely supported format, and it handles wide colour gamut and HDR, which JPEG cannot.

JPEG is a lossy image format designed for photographs. It works by discarding detail the human eye is least likely to notice, particularly in colour and in smooth gradients, which is why it compresses photos far better than it compresses text or line art.

Where AVIF files come from: Performance-focused websites and modern image pipelines.
Where JPG is used: Digital cameras, phone screenshots on Android, and essentially every photo on the pre-2015 web.

AVIF vs JPG

The two formats solve different problems, which is why converting between them involves trade-offs rather than a straight upgrade.

AVIF compared with JPG
Property	Source	Target
Compression	Lossy or lossless	Lossy
Transparency	Yes	No
Animation	Yes	No
Introduced	2019	1992
Browser support	Modern browsers only. Limited desktop app support.	Opens everywhere — every browser, OS and device.

AVIF is stronger at: The best compression of any broadly supported image format. Handles HDR and wide colour gamut. Supports transparency and animation.
JPG is stronger at: Opens on literally every device, browser and application ever made. Small files for photographic content. Adjustable quality, so you control the size/fidelity trade-off.

Why convert AVIF to JPG?

People make this switch when they run into the limits of AVIF: the file needs to be opened outside a browser, or you need fast bulk encoding. JPG is the better fit when you are sharing a photograph and compatibility matters more than squeezing out the last few kilobytes.

AVIF limitations that prompt the switch: Encoding is slow compared with JPEG or WebP. Desktop application support is still thin. Very low bitrates can smear fine detail in a distinctive way.
What you give up: No transparency — there is no alpha channel at all. Visible artefacts around sharp edges and text.

Does converting AVIF to JPG reduce quality?

AVIF stores your data exactly; JPG does not. Some detail is discarded permanently in exchange for a much smaller file, which is usually the right trade for sharing and publishing. Keep your AVIF original if it is the only copy — the conversion cannot be undone.

Saving a JPEG at 100% quality is still lossy — it is a large file that has been through the same discarding process, not a lossless copy.
