About AVIF to JPG
More and more websites serve images as AVIF because the files are tiny, so pictures you save from the web increasingly end up as .avif files. Many apps still can't open them: older versions of Windows Photos, Photoshop, Office, online forms and print services often reject AVIF. This converter decodes each AVIF and saves it as a standard JPG at the quality you choose, with an optional maximum size and a background colour for any transparent areas. Convert one image or a whole folder at once, and download them individually or as a ZIP.

What is an AVIF file?
AVIF is one of the newest image formats on the web. It is based on the AV1 video codec and compresses photos even more efficiently than WebP: an AVIF can be half the size of a JPG of similar quality. It also supports transparency, high dynamic range and wide colour. Sites such as Netflix, YouTube and many online shops now serve AVIF to make pages load faster, and modern phones can save photos in it too.
Because it's so new, support outside the browser is patchy. Older versions of Windows Photos, Photoshop, Lightroom, Microsoft Office, Google Slides and many online forms, printing services and email apps can't open AVIF files. Read more in the AVIF format guide.
Why convert AVIF to JPG?
JPG is the format every device and app understands. Converting AVIF images to JPG makes them easy to edit in any program, attach to an email, insert into a document or presentation, upload to a form or print. It's the simplest fix when you saved an image from a website and it won't open where you need it.
For logos, icons or images with a transparent background, convert to PNG instead, which keeps the transparency.
Quality and size
Use 90% quality to keep the picture looking the same as the AVIF. The JPG will be bigger, often two to three times, because JPG compresses less efficiently; that's the price of compatibility. To keep files small, lower the quality to 80% or set a maximum width, for example 1600 pixels for web use or email.
Transparent areas in the AVIF are filled with a background colour, white by default, and you can choose another colour if the image will sit on a coloured page.
Why some photos turn out bigger
It surprises people that the JPG is larger than the AVIF it came from. AVIF's compression is simply much more efficient, so a 200 KB AVIF can need 500 KB or more as a JPG to look the same. Nothing is wrong with the conversion; it's the cost of using the more compatible format. If you need a specific file size, convert first, then use the image compressor with a target size in KB.
Converting AVIF on a phone or computer
Add one image or a whole batch, convert, and download each JPG or everything as a ZIP. It works in any modern browser on Windows, Mac, iPhone, iPad and Android, so you don't need to install a codec or plug-in.
Images from websites can also arrive as WebP; those convert the same way with WebP to JPG. To compare the newer formats, see AVIF vs WebP.
Should you avoid AVIF?
Not at all. For websites, AVIF is excellent and saves bandwidth. The issue is only compatibility once you take an image out of the browser. Keep the AVIF originals if storage matters, and convert copies to JPG whenever you need to share or edit them in other apps.
Questions
Why do images from websites save as AVIF?
Sites serve AVIF because it's much smaller than JPG at the same quality, so pages load faster. Your browser saves the file it received.
Will the JPG be bigger?
Usually, because JPG compresses less efficiently than AVIF. The picture looks the same.
What happens to transparency?
JPG has no transparency, so transparent areas are filled with the background colour, white by default. Use AVIF to PNG to keep it.
Are my images uploaded?
No. Conversion happens in your browser.
