AVIF is the newest image format on the web. Because it makes photos remarkably small, more and more websites, online shops and image CDNs serve AVIF, and when you save an image from your browser you often end up with a .avif file. Then the trouble starts: many photo editors, office apps, older computers, messaging services and upload forms don't recognise it.
This converter turns AVIF images into JPGs, the format everything understands. It runs in your browser using its built-in AVIF decoder, handles whole batches at once, and never uploads your images.
Before
AVIF, 1600 × 1067 web photo
≈ 60–150 KB
Very small, but many editors, older apps and upload forms reject it.
After
JPG, same size
≈ 250–600 KB
Opens in every app, viewer, form and operating system.
Typical for a web photo at 90% JPG quality. JPG is less efficient than AVIF, so the file grows, but the picture does not gain or lose visible detail.
Drop .avif files into the workspace above, or click to choose them. Add several at once for a batch.
JPG is preselected. Set the quality slider; 90% gives a good balance of size and detail.
Click Convert Now. Each image is decoded by your browser and saved as a JPG.
Save each JPG or download the whole batch as a ZIP file.
| Where it is going | Convert to | Why |
|---|---|---|
| Email, documents, upload forms | JPG | Accepted everywhere |
| Photo editing apps | JPG or PNG | PNG avoids another lossy save |
| Images with transparency | PNG | JPG fills transparent areas with white |
| Your own website | WebP | Small and widely supported |
| Printing services | JPG | The format print labs expect |
AVIF stands for AV1 Image File Format. It stores a single frame compressed with AV1, the royalty-free video codec developed by the Alliance for Open Media, whose members include Google, Apple, Microsoft, Mozilla, Netflix and Amazon. AV1 compression is far more advanced than the 1990s technology behind JPG, so an AVIF photo is often around half the size of a JPG that looks the same, and sometimes much smaller.
For websites that means faster pages and lower bandwidth bills, which is why image services convert photos to AVIF automatically for browsers that support it. AVIF also supports transparency, wide colour, HDR and high bit depths, making it a capable all-round format.
Browser support arrived quickly: Chrome in 2020, Firefox in 2021, Safari in 2022 and fully in Safari 16.4 in 2023, and Edge in 2024. Support outside the browser is patchier. Older versions of Windows and macOS, many image editors, office suites, print services, government and job portals, and plenty of messaging apps still can't open or accept .avif files.
Converting to JPG solves that in one step. JPG is supported by every device and service made in the last thirty years, so the image will open wherever you send it.
Your browser decodes the AVIF into full pixels, and the converter encodes those pixels as a JPG at the quality you set. At 90% or higher the JPG looks the same as the AVIF. JPG compression adds a small amount of its own loss, but it cannot bring back detail the AVIF compression already removed, so the JPG is a faithful copy of the image as you see it.
The JPG will usually be larger than the AVIF, often two to four times. That is not a mistake: JPG is simply a less efficient format. If size matters, reduce the quality a little, resize the image with the Image Resizer, or compress it to an exact size with the Image Compressor.
AVIF can do things JPG can't. Transparent areas become white in the JPG, because JPG has no alpha channel; pick PNG as the output if you need transparency. HDR and 10- or 12-bit AVIF images are converted to standard 8-bit colour, which looks correct on every screen. Animated AVIF images are saved as a single still frame.
The converter can also output PNG and WebP, so you can choose the best target for each image without leaving the page.
The images are decoded and converted entirely in your browser. Nothing is uploaded, so there is no waiting and no copy of your files on a server. The JPGs are written without metadata, which removes any EXIF information the AVIF contained.
Each format has its place. JPG is the universal choice: every app, printer, form and operating system accepts it, which is why it is the right target when an AVIF file won't open somewhere. WebP sits in the middle: smaller than JPG, supported by all current browsers and most modern apps, and a good choice for images going back onto a website. AVIF is the smallest of the three and ideal for websites that serve it to supporting browsers, but it is still the least compatible outside the browser.
A practical rule: convert to JPG for anything leaving your computer (email, forms, documents, printing), to WebP for web pages, and keep AVIF only when you know the destination supports it.
Most AVIF files come from saving images out of a web page. If you need the image in a specific format often, check whether the site offers a download button, which frequently provides a JPG or PNG original. Otherwise, converting here takes a few seconds and works for any number of files at once.
Turn AVIF downloads into JPGs that open in any app or editor.
Portals that accept only JPG or PNG reject .avif; convert first.
Office apps that don't read AVIF can insert the JPG.
Send a JPG so the recipient can open it on any device.
AVIF (AV1 Image File Format) is a modern image format based on the AV1 video codec from the Alliance for Open Media. It produces much smaller files than JPG at the same visual quality, so websites use it to load faster. That is why images you save from the web are often .avif files.
Browsers support AVIF, but many desktop apps, older operating systems, image editors, upload forms and messaging services still don't. Converting to JPG makes the image open everywhere.
Saving as JPG adds a little compression, but at 90% quality or more the difference isn't visible. The JPG can't recover detail the AVIF compression already removed. If you plan to edit the image heavily, convert to PNG instead to avoid a second lossy step.
AVIF compresses roughly twice as efficiently as JPG, so the same picture needs more bytes as a JPG. That is expected; lower the quality slider or use the Image Compressor if you need a smaller file.
JPG has no transparency, so transparent areas become white. Choose PNG as the output format to keep them transparent.
Current versions of Chrome, Edge, Firefox and Opera, and Safari 16.4 or later on Mac, iPhone and iPad. The conversion uses your browser's own AVIF decoder; if your browser is too old, the tool tells you to update it.
The converter saves a single still image. For an animated AVIF, the JPG contains one frame of the animation.
No. Decoding and JPG encoding both happen in your browser, and the JPGs are saved directly to your device.
