AVIF is a newer image format that many websites and image CDNs serve because it is very small for its quality. When you right-click a product photo or a picture in a news article and save it, you may end up with a .avif file. Then the trouble starts: your photo viewer, Word, an older Photoshop, a marketplace uploader or a client's laptop cannot open it. JPG is the format that opens everywhere, so converting is the quickest fix.
This converter uses your browser's own AVIF decoder. A note at the top of the tool checks your browser and tells you right away if it can read AVIF. If it can, the conversion runs on your device and nothing is uploaded.
How to convert AVIF to JPG
- Check the message above the drop box. A green note means your browser can open AVIF.
- Drop your .avif files into the box, or click it to choose them. Batches of up to 300 files are fine.
- Keep JPG selected and set the Quality. 80 to 85 gives small files that still look sharp; 90 or more suits printing and further editing.
- If some images have transparent areas, pick the Background color that should fill them. White is the default.
- Click Convert all, then download single files or everything as a ZIP.
Choose PNG instead of JPG when the AVIF has a transparent background you want to keep, such as a logo or a product cutout.
Which browsers can open AVIF
The converter relies on the browser to decode AVIF, so support matters. As of October 2026, caniuse.com lists these first versions with AVIF support:
| Browser | Supports AVIF from | Notes |
|---|---|---|
| Chrome (Windows, Mac, Android) | Version 85 | Released in 2020; every current Chrome works |
| Microsoft Edge | Version 121 | Released in early 2024; older Edge versions cannot read AVIF |
| Firefox | Version 93 | Released in 2021 |
| Safari on Mac | Version 16.4 | 16.1 to 16.3 had partial support on macOS Ventura |
| Safari on iPhone and iPad | iOS 16 | All browsers on iOS use the same engine |
| Samsung Internet | Version 14 | Android phones from Samsung |
| Opera | Version 71 | Built on Chrome |
caniuse.com estimates that about 96 percent of web users have a browser that displays AVIF. If the tool reports that your browser cannot open AVIF, update it or open this page in a current Chrome, Firefox, Edge or Safari. There is no server fallback, because the whole point of the tool is that your files stay on your device.
AVIF, WebP and JPG compared
| Format | Introduced | Typical size for the same photo | Transparency | Opens in most desktop apps |
|---|---|---|---|---|
| JPG | 1992 | Largest of the three | No | Yes, everywhere |
| WebP | 2010 | Smaller than JPG | Yes | Mostly, older software may not |
| AVIF | 2019 | Usually the smallest | Yes | Often not, especially older apps |
The pattern is simple: newer formats are smaller but less widely supported outside browsers. Websites benefit from AVIF because the browser handles it, while the files you keep, send and edit are easier to work with as JPG or PNG. If you run a website yourself, keep AVIF or WebP for the pages and keep JPG copies for everything else.
Picking a JPG quality
AVIF files are often tiny because they are compressed hard. Converting to JPG does not bring back detail; it re-encodes what the AVIF shows. That makes the quality slider a size decision more than a looks decision:
- 75 to 80: small files for web pages, chat and email. Fine for most photos.
- 85: a good default for product photos and blog images.
- 90 to 95: for printing or when you will edit the JPG again. Files get noticeably larger.
The result row shows the old and new file size so you can see the effect. A JPG is usually larger than the AVIF it came from, often two to four times, because JPG is an older and less efficient format. That is normal and is the price of compatibility.
How AVIF files end up on your computer
Most people never choose AVIF; it arrives on its own. When a browser requests an image, it tells the server which formats it accepts. Image services and CDNs answer with the smallest format the browser can show, which is often AVIF in a current Chrome or Firefox. Right-click, Save image as, and that AVIF is what lands in your Downloads folder, even though the address of the image may still end in .jpg. Screenshots tools, some phone galleries and a few camera apps can also save AVIF. So a file that "used to be a JPG" on a website can arrive as AVIF on your disk, and converting it back is the normal fix.
Common reasons to convert AVIF
Saving images from websites and marketplaces
Image CDNs serve AVIF to browsers that accept it, so "Save image as" often hands you an AVIF even when the page looked like a normal photo. Converting to JPG makes that picture usable in documents, slides and image editors. Respect the image owner's rights: converting a file does not change who owns it.
Uploading to platforms that only take JPG or PNG
Many upload forms still accept only JPG, PNG and GIF. Etsy's help center, for example, lists .jpg, .gif, .png, .svg and .heic for shop images (checked October 2026), so an AVIF has to be converted first.
Sharing with people on older software
A JPG opens on any computer, phone, TV or photo frame. If you are sending pictures to a client or a printer, JPG avoids a round of "I cannot open this file" emails.
Tip: Importing products from AliExpress, Amazon or other stores? AM Jarvis's Chrome Extension imports the product with its images straight into your Shopify or WooCommerce store, so you do not have to save and convert each picture by hand.
Troubleshooting
- The note says your browser cannot open AVIF: update the browser. On a Mac with Safari 16.0 or older, use Chrome or Firefox instead; on Windows, use a current Edge or Chrome.
- A file fails with "not an image the browser can read": it may be cut off or not really AVIF. Some sites send a different format under an .avif name. Open it in a browser tab to check it shows.
- Colors look a little flatter: some AVIF images store HDR or wide color. JPG holds standard 8 bit color, so very bright highlights are mapped into the normal range.
- The file names end in .jpg but the old ones also had odd names: the converter keeps the original base name and only changes the extension, so a name like
image-1xbecomesimage-1x.jpg. Rename in bulk later if you like.
A quick example
A designer collects 15 reference images for a client mood board, and 11 of them save as AVIF from different sites. The client works in PowerPoint on an older Windows laptop. Converting the 11 files to JPG at quality 85 takes a few seconds, and the ZIP drops into the shared folder next to the other 4 images. Every slide now opens on the client's machine without any extra software.
Limits and privacy
Animated AVIF files are converted to a still JPG of the first frame. Very large AVIF images (above 12,000 pixels on a side or 100 megapixels) are refused with a clear message, since browsers cannot create JPGs that big reliably. Camera data inside the AVIF is not carried into the JPG. The conversion happens on your device and the files are never uploaded.
