Convert AVIF to JPG
Turn an AVIF image saved from a website into a JPG that apps, editors and upload forms open. It gets bigger, and here is by how much. No upload.
How to convert AVIF to JPG
- Drop the AVIF on the box above, or up to 20 at once. The file picker here lists AVIF files.
- Convert to already shows JPEG at 80%.
- Press Convert image. The JPG will be larger than the AVIF; that is expected.
- Download the JPG, or every converted file together as a ZIP.
AVIF, the format you did not ask for
AVIF is the newest image format in wide use on the web, and the most compact one. Sites send it to browsers that can show it, so a picture you save from a page or an image search can arrive as .avif. My own site makes AVIF copies of my photos for exactly that reason. Browsers open them without trouble; the photo editor, the slide program or the upload form that has never heard of AVIF does not.
I made AVIF copies of three of my published photos with the settings my site uses for the ones it serves, then turned each into a JPG on this page in Chromium at the starting 80%.
How much bigger the JPG is
| Image | AVIF | JPG at 80% |
|---|---|---|
| Lake Jasna, June 2019 | 960 × 1200 px, 55.6 KB | 141.6 KB, 154.9% larger |
| Clay figure, Metelkova, March 2023 | 1200 × 800 px, 48.0 KB | 134.4 KB, 179.7% larger |
| Red bicycle, Metelkova, March 2023 | 1200 × 800 px, 110.3 KB | 242.0 KB, 119.3% larger |
Every JPG was more than twice the size of its AVIF, the clay figure almost three times, while the pixel size stayed the same. That is not the converter wasting space. The AVIF copies are small because the format packs a photo very tightly, and JPEG cannot match it.
Can the JPG be as small as the AVIF?
Not at a quality you would want. I tried the lake at other settings: at 90% the JPG was 226.3 KB, and even at 60% it was 86.5 KB, still 55.7% larger than the 55.6 KB AVIF. If the JPG must be smaller than that, give it fewer pixels with the Image Resizer instead of pushing the quality down further.
Who opens AVIF and who does not
Current versions of Chrome, Edge, Firefox and Safari all display AVIF, which is why websites can use it. This page relies on that: your browser decodes the AVIF, and the converter writes the JPG from it on your device.
Outside the browser the picture is mixed. Plenty of desktop programs, older phone galleries and upload checks still accept only JPG and PNG. A JPG at 80% is the safe answer for all of them.
Tips for converting AVIF to JPG
- Convert once and keep that JPG. Each later JPEG save takes a little more detail away.
- Leave the quality at 80% unless the JPG must be smaller; a higher setting mostly adds size.
- An AVIF with a transparent background gets a white one in the JPG.
- For an upload limit, run the JPG through the Image Compressor at the size you need.
Privacy
Your image never leaves your device. Conversion happens entirely in your browser, so nothing is uploaded or stored, and you do not need an account. Support for HEIC files is included on this site and also runs in your browser.
Frequently asked questions
What is an AVIF file?
An image in the AV1 Image File Format, built on the AV1 video codec. It stores photos in far less space than JPG: my lake photo is 55.6 KB as AVIF and 141.6 KB as a JPG at 80%. Browsers show it, many other programs do not.
Why are images saving as AVIF?
Because the website or image search sent your browser an AVIF, the smallest version it had, and the browser saves what it received. The site chose the format to load faster; nothing is wrong with your browser.
Is AVIF better than JPEG?
For file size, clearly: my three photos were between 2.2 and 2.8 times larger as JPG at 80%. JPEG is better when the file has to open everywhere, in old programs, in any phone gallery and in strict upload forms.
Why can't I open an AVIF file?
The program you are using does not read AVIF yet. Opening the file in a browser works, since current Chrome, Edge, Firefox and Safari all show AVIF. To use it anywhere else, convert it to JPG here, which every program opens.
Can I convert many AVIF images at once?
Yes, up to 20 in one go. Drop them all on the box, press Convert images and each one becomes a JPG at the same quality. The list lets you save them one by one, or you can take everything as a single ZIP.
