What AVIF Viewer is for
Use the AVIF Viewer when an AVIF image lands on a device or app that will not open it. The image is decoded natively by your browser on any operating system, with a one-click option to save a PNG copy.
- Open AVIF images on Windows, Android, Linux or any device with a browser.
- Check the dimensions and file size of an AVIF before using it.
- Save a lossless PNG copy of any image you view.
- View files safely, since nothing is uploaded.
Best practices for better results
Image optimization works best when you choose the right balance between file size, visual quality, dimensions, format compatibility and privacy. These tips help you get a cleaner result.
- Use the viewer when you only need to check a file, not convert it.
- Save as PNG when you need a copy that opens in any app.
- For batches you plan to share, use AVIF to JPG instead of saving one by one.
- A current browser is all you need: no codecs or extensions.
Open AVIF files without installing anything
This AVIF viewer exists for the moment an image saved from a website refuses to open on your computer. Windows Photos needs a separate AV1 extension to display AVIF, older photo viewers cannot handle the format at all, and yet every current browser decodes it natively. So instead of hunting for codecs, drop the file here and see it instantly, on any operating system.
Each image is shown full size with its dimensions and file weight, and a Save as PNG button produces a lossless copy that opens anywhere.
HOW TO VIEW AN AVIF FILE
- Drop the AVIF file onto the upload area, or click to browse
- Click View images: each one is decoded by your browser and displayed below
- Check the dimensions and original file size shown under every image
- Use Save as PNG when you want a copy that opens in any app
Viewing versus converting
Viewing is enough when you just need to check what a file contains. The moment the image needs to go somewhere else, convert it instead: AVIF to JPG for universal compatibility, AVIF to PNG for a lossless editing copy, or AVIF to WebP for platforms that take WebP but not AVIF.

AVIF Viewer FAQ
How do I open an AVIF file on Windows?
Drop the file onto this page and it displays instantly. Windows Photos needs the AV1 video extension to open AVIF, and many older apps cannot open it at all, but every current browser decodes it natively.
Why will my photo app not open AVIF images?
AVIF is a young format, and support outside browsers is still catching up. Viewing here works everywhere; converting to JPG or PNG fixes it permanently for other apps.
Can I save a copy after viewing it?
Yes, every image has a Save as PNG button that downloads a lossless copy you can open and edit anywhere.
Is my image uploaded when I view it?
No. Your browser decodes the AVIF natively on your own device, so the file never touches a server.
