Drop AVIF files here or click to select
Up to 20 files at once. Nothing is uploaded, conversion runs in your browser.
85 to 95 keeps photos looking identical at a much smaller size.
JPEG has no transparency, so see-through pixels get this colour.
Converting AVIF to JPG
AVIF is the image format that arrived with the AV1 video codec in 2019, and it is now what many websites hand you when you right click and save a picture. The file lands on your disk with a .avif extension and then refuses to open in Windows Photo Viewer, in older Photoshop builds, in most print shop upload forms and in plenty of mail clients. This converter rebuilds the picture as an ordinary JPG that every one of those programs has understood for thirty years.
The people who need this most are not photographers. They are estate agents pasting a floor plan into a listing system, teachers dropping an illustration into a worksheet, and office workers whose company laptop still runs a 2019 image viewer. Anyone building a slide deck, filling in a government upload form or sending photos to a print service hits the same wall: the upload button greys out, or the file shows up as a blank icon.
Your browser already contains a full AVIF decoder, because Chrome added support in version 85 and Safari followed in version 16. The tool asks the browser to decode the file, paints the result onto a canvas and asks it to write JPEG bytes back out. Nothing is uploaded. That also means the conversion only works in a browser new enough to read AVIF in the first place, which in practice is anything released after late 2022.
Expect the JPG to be two to four times larger than the AVIF you started with, because AVIF reaches the same visual quality at roughly half the bytes. A 180 KB AVIF photo often lands around 500 KB as a JPEG at quality 90. Keep the slider between 85 and 95 for photographs. AVIF also supports transparency and JPEG does not, so any see through pixels are filled with the background colour you pick before converting.
Because AVIF is already an efficient format, converting to JPG makes files bigger rather than smaller. If the result is too heavy for an attachment limit, run it through our Image Compressor afterwards, and use the Image Resizer when the picture is far larger in pixels than the place it needs to fit. The original AVIF is worth keeping for anything that will end up back on a website.
How the AVIF to JPG Converter Works
- 01Drop your .avif files onto the box, or click it and pick up to 20 at a time from your file browser.
- 02Choose a JPEG quality. 90 is the sweet spot for photographs; drop towards 75 only when the file has to be tiny.
- 03Pick a background colour. AVIF can be partly transparent and JPEG cannot, so those pixels get filled with your choice.
- 04Download the JPG files one by one, or use Download all to save the whole batch in sequence.
Getting a Usable JPG Out of an AVIF File
Most people arrive here because a website served them an AVIF and something downstream refuses it. The fastest way through is to convert once, at high quality, and keep both files. Start with the quality slider at 90. At that setting the JPEG is visually indistinguishable from the AVIF for ordinary photographs, and you avoid the blockiness that shows up around 60 and below. Because the source has already been compressed once, every further compression stacks on top of the first, so a low setting here produces worse results than the same setting applied to an untouched camera file. If the AVIF has transparent regions, set the background colour before you convert rather than after, since JPEG has no way to record which pixels used to be see through. White works for documents and print, and matching the page background works for anything going into a web layout. When you are converting a batch that will end up in one document, keep the settings identical across the batch so the images look consistent next to each other. Finally, check the size report at the top of the results block. If the JPEG came out much larger than the AVIF, that is expected, not a bug.
When to Use AVIF to JPG
Convert when the destination decides for you. Print services, older desktop software, government and insurance upload forms, digital photo frames, some point of sale systems and a lot of corporate document workflows accept JPEG and nothing newer. The same applies when you are handing a file to somebody whose setup you do not control. Do not convert when the picture is going back onto a website you run, because AVIF is smaller and faster there. Do not convert when you plan to edit the image heavily either, since JPEG loses a little quality on every save.
Common Use Cases
- Saving a product photo from a modern web shop and getting it into a supplier form that only takes JPEG.
- Preparing images for a printing service whose upload page rejects anything except JPEG or TIFF.
- Fixing AVIF files that show as blank icons on a work laptop with an older Windows build.
- Shrinking the JPEG afterwards when the mail server bounces the attachment. Compress Images Online - No Upload Required
- Checking what camera and location data the original file carried before you convert. Image Metadata Viewer - EXIF & GPS Data
Expert Tips
- Convert once, at quality 90, and archive that JPG. Repeatedly re-saving a JPEG degrades it a little every time.
- If the AVIF was transparent, match the background colour to whatever it will sit on. A white fill on a dark slide looks like a mistake.
- Batches of 20 run in sequence rather than in parallel, so a folder of large images takes a moment. Leave the tab open until the counter stops moving.
- Your browser has to be able to decode AVIF for this to work at all. If files fail with a read error, update the browser rather than the file.
Frequently Asked Questions
- AVIF is only a few years old. Browsers picked it up quickly, but desktop applications did not. Windows needs a codec from the Microsoft Store, older macOS builds have no support at all, and many editors added it only in recent versions. Converting to JPG sidesteps the whole problem.
- At quality 90 the difference is invisible in normal viewing for almost all photographs. You are compressing an already compressed image, so fine detail in noisy areas such as foliage or fabric texture can soften slightly. Zoomed in at 400 percent you may spot it; on screen or in print you will not.
- AVIF is simply a more efficient codec. It reaches the same perceived quality at roughly half the file size of JPEG, so going in this direction costs you bytes. A doubling or tripling of file size is completely normal and does not mean anything went wrong.
- AVIF does support animation, but JPEG does not. Only the frame the browser displays first is converted, and the rest of the sequence is dropped. If you need the motion, keep the AVIF or export a video instead.
