How to use it

1
Add your AVIF files
Drag them onto the drop area, choose them from your device, or paste them from your clipboard. You can queue several at once. Nothing is sent anywhere — the file stays on this device.
2
Adjust the settings if you want to
The defaults suit most people. Open Advanced to control quality and metadata removal.
3
Convert and download
Press Convert. Everything happens on your own device — nothing is uploaded. Download files one by one, or grab them all as a ZIP.

Privacy, in plain words

Is it safe? Your AVIF file is not uploaded anywhere

What “uploaded” normally means. On most online converters, pressing the button copies your file across the internet onto a computer owned by that website. That copy is what the word “upload” means, and it is the part nobody explains.

What happens instead. This site does not do it. There is no server here that receives files, so your AVIF file is read, converted and handed back by the browser you are using right now. It never travels — so there is no copy to store, read, leak or hand over.

Check it yourself in ten seconds

Turn off your Wi-Fi after this page has loaded, then convert a file anyway. It still works, because everything needed is already on your device.

The longer explanation of how this works, and the full detail of what is and is not stored on the privacy page.

Why this matters more than it sounds

Photographs carry more than what is in the frame — most also carry the time, the device and often the GPS coordinates where they were taken. It matters more than it sounds, because of what images usually are:

Screenshots of private messages

conversations that included other people

Photos of ID cards and licences

the usual way people send identity documents

Screenshots of bank transfers

account details, and proof of what you paid whom

Medical scans and photographs

X-rays, results, images of a condition

A file that is never sent cannot be kept, leaked, subpoenaed or used to train anything. That is a property of how this works, not a promise about how carefully it is run.

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.

Measured, not estimated

What converting AVIF to JPG actually costs

It depends entirely on the content: across the samples the JPG ranged from 21% smaller to 6.9× larger, with a middle case 2.6× larger.

Nothing came through untouched. Similarity against the input file ranged down to 0.965, where 1.000 would mean no visible change at all.

Transparency did not survive: JPG has no alpha channel, so anything see-through in the source was flattened onto a white background. That is the single most common surprise in this conversion, and it is not recoverable afterwards.

Each row is one sample chosen to isolate a property these formats treat differently.
Sample	AVIF in	JPG out	Change	Similarity
Smooth gradientContinuous tone with no detail — the easiest thing to compress, and where banding shows first.	4.6 KB	12.1 KB	2.6×	0.993
Hard-edged text and UIHigh-contrast edges. This is where JPEG's ringing artefacts appear and where PNG wins.	42.3 KB	85.3 KB	2.0×	0.985
Film-like noiseRandom detail. Incompressible by design — the worst case for every lossy codec.	242 KB	192 KB	−21%	0.965
Flat colour blocksLarge areas of one colour — a logo or a chart. Lossless formats should crush this.	711 B	4.8 KB	6.9×	0.997
Soft alpha edgeA transparent gradient. JPEG cannot store it at all, which is the single most common reason a conversion surprises someone.	2.3 KB	12.9 KB	5.5×	0.994

Produced by a stand-in encoder. Your browser's own encoder has no equivalent outside a browser, so this was measured with the same codec at the same quality from a different implementation. Expect the shape of the answer to hold and the exact bytes to differ.

Samples are generated from a fixed seed rather than taken from real photographs or documents, so the corpus is reproducible and carries no licensing question — and so the numbers predict the shape of your result rather than its exact size. Measured 2026-10-01. The method, and the command that regenerates every figure on this page, are on the how it works page.

AVIF to JPG Converter — questions

How do I convert AVIF to JPG?

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

Is it safe to convert AVIF files here — are they uploaded to a server?

No, nothing is uploaded. On most online converters, pressing the button copies your file across the internet onto a computer owned by that website; it is converted there and sent back. That copy is what "upload" means, and it is the part that puts your file out of your control. This site does not do it. Your AVIF file is read and converted by the browser you are using right now and never leaves this device, so there is no copy for anyone to store, read or hand over. You can prove it: turn off your Wi-Fi after this page loads and the conversion still works.

Can I convert confidential AVIF files, like bank statements or contracts?

Yes, and that is the case this site was built for. Because the file never leaves your device, a confidential document is no more exposed than it is sitting in your own folder — there is no transfer, no copy on someone else's hardware, no retention period to read about and no staff with access. Nothing is logged about the file either: not its name, not its size, not its contents. The one thing worth saying plainly is that this protects the file in transit and at rest on our side, not from anything already on your own computer.

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 images may run out of memory on a phone — those are better converted on a laptop.
