This converter reads your AVIF file, decodes it at full resolution and re-encodes it as JPG. Everything happens inside your browser using the same image engine the page already loaded, so there is no upload, no queue and no file-size limit imposed by a server.
AVIF is the smaller file; JPEG is the one that everything can open. Convert when a program, printer or upload form refuses the AVIF, and accept a modest increase in file size and a small quality loss as the price of that compatibility.
AVIF compresses harder than any other web image format, especially at the low quality settings where JPEG falls apart, and it supports transparency and HDR. The trade-offs are slower encoding and the newest support of any format here - current Chrome, Edge, Firefox and Safari all read it, but older software does not.
JPEG is lossy: it discards the detail your eye is least likely to notice, which makes it the smallest sensible option for photographs but a poor one for text or sharp edges. It cannot store transparency, and every lossy save throws away a little more - which is why you should edit the original and make a JPEG last, not first.
One change is unavoidable: AVIF can hold a transparent background and JPG cannot, so any transparent area will come out filled with solid white. If the image needs to stay transparent, choose a target format that supports it instead.
JPG is a lossy format, so the quality setting decides how much detail is kept. Around 90% is visually identical to the source for most images, and going below about 70% starts to show around edges, text and fine texture.
Conversion is only as good as its source. Working from the original file always beats working from a file that has already been converted once, because lossy formats discard a little more detail at every save. If you need several output formats, start from the original each time rather than converting one result into the next.
How to convert AVIF to JPG
Drop your AVIF file onto the page, or click to browse. You can add several files at once.
Leave the quality at the default for most images, or lower it if the file must be small; set a maximum width if you also want to reduce the pixel dimensions.
Press convert, check the preview, then download the files individually or all of them together as a ZIP.
FAQ
Is my file uploaded anywhere?
No. The conversion runs entirely inside your browser, so the image never leaves your device. That is also why there is no server-side size limit and no waiting in a queue - and why the tool works offline once the page has loaded.
Do I lose quality by converting back and forth?
Yes, whenever a lossy format is involved. Each lossy save discards a little more detail, and repeating the round trip compounds it. Convert from the original file rather than from a copy that has already been through a converter.
Will the file get bigger or smaller?
It depends on the direction. Moving to a lossless format such as PNG usually makes a photograph several times larger, because nothing is being discarded. Moving to a lossy format such as JPEG, WebP or AVIF normally makes it smaller - often dramatically so - with the exact result depending on the quality setting you choose.
Can I convert several files at once?
Yes. Add as many images as you like and they are processed one after another in your browser; you can then download them individually or as a single ZIP. A very large batch takes longer on a phone, since the work is done by your own device.
Will the colours change?
Pixel values are carried over directly when both formats store colour the same way, so there is normally no visible shift. Colours can move slightly if you convert to a format with a smaller colour space, between different colour profiles, or when a browser applies its own colour management - and converting to GIF will reduce the image to 256 colours.
Can I convert the images back afterwards?
Yes, every direction is available as its own page, so you can go JPG to AVIF as well. Just remember that a round trip through a lossy format does not return the original file - it returns a slightly degraded copy of it.

Choosing between JPG, PNG, WebP and AVIF
These formats solve different problems, and picking the wrong one costs you either quality or file size. JPG is the safest choice for photographs and for anything you need to send to someone else, because every device and program opens it - but it is lossy and has no transparency. PNG is lossless and supports transparency, which makes it right for logos, screenshots, diagrams and anything with sharp edges or text, at the cost of a much larger file. WebP typically beats JPG by 25-35% at the same visible quality and supports transparency, but a few older programs still cannot open it. AVIF compresses even further, especially at low quality settings, but encoding is slower and support is the newest of the four. A practical rule: JPG to send, PNG to edit, WebP for your own website, AVIF when every kilobyte counts and you have checked that your audience can open it.
How much quality you actually lose
Lossy compression throws away detail your eye is least likely to notice - first fine texture, then edges. In practice most photographs look identical to the original down to roughly 75-80% quality, and differences only become obvious around faces, hair, foliage, fabric patterns and text. That is why a portrait and a screenshot need different settings: a face at 60% shows blotchy skin where a landscape at 60% still looks fine. Resizing matters more than quality for perceived sharpness: halving the pixel dimensions usually saves far more than dropping quality from 90 to 60, and the result looks better. If you need a specific file size, reduce dimensions first, then quality, and stop as soon as you hit the target rather than going lower than necessary.
