Quick answer
Go to pixeltools.io/convert/avif-to-jpg, drop your AVIF file in, and download the JPG. It converts instantly in your browser — nothing is uploaded to a server, and no software installation is needed. AVIF is a modern format with excellent compression, but most apps, email clients, and platforms still don't support it, which is why converting to JPG is often necessary.
What is AVIF and why can't I open it?
AVIF (AV1 Image File Format) is a relatively new image format developed by the Alliance for Open Media. It offers significantly better compression than JPG and WebP — meaning smaller file sizes at the same visual quality. Google Chrome and Firefox support it natively, and some web services use it to serve optimized images. However, AVIF support is still limited: Windows Photos doesn't open AVIF files by default, macOS Preview added support only in macOS Sequoia (2024), and most image editing software still doesn't handle it. This is why you might download an AVIF from the web and find you can't open it.
Does converting AVIF to JPG lose quality?
Converting AVIF to JPG introduces some quality loss, but in practice it's minimal if you export at a reasonable quality setting (80 or higher). AVIF stores images with better compression than JPG, so the AVIF source is already high quality. The conversion step decodes the AVIF (losslessly to raw pixels) and then re-encodes as JPG. At quality 85, the JPG output looks virtually identical to the AVIF original. The file size will increase compared to the AVIF, since JPG is less efficient, but it will be universally openable.
How to convert AVIF to JPG step by step
1. Open pixeltools.io/convert/avif-to-jpg in your browser. 2. Click 'Choose files' or drag your AVIF file into the drop zone. 3. The conversion happens immediately — no waiting. 4. Click 'Download' to save your JPG.
You can convert multiple AVIF files at once by selecting them all in the file picker. Each converted JPG is available for individual download. The tool works on Windows, Mac, Linux, iOS, and Android — any device with a modern browser.
Other ways to open or convert AVIF files
Besides PixelTools, there are a few other ways to handle AVIF files. On Windows, you can install the AVIF Image Extension from the Microsoft Store (free), which lets Windows Photos and File Explorer preview AVIF files — but you still can't edit them in most software. On Mac, macOS Sequoia and later can open AVIF files in Preview. In Chrome or Edge, you can drag an AVIF file directly into the browser address bar to view it. For batch conversion or automation, ImageMagick (command line) supports AVIF. For a quick, no-install, browser-based conversion to a standard format, the PixelTools converter is the fastest option.
Should I convert to JPG or PNG?
Convert to JPG if you need the smallest file size and the image is a photo without transparent areas. Convert to PNG if the image has a transparent background, contains logos or icons with sharp edges, or you need lossless quality (no compression artifacts). JPG is the better choice for photos going to email, social media, or websites. PNG is better for logos, screenshots, or images where you need to preserve transparency.
