How to convert AVIF to JPG
- Tap Choose image above and pick one or more .avif files.
- On the Convert tab, Convert to is already JPG. Keep High (92%) unless you need a smaller file.
- Tap Convert. Several files are converted one after another and packed into a ZIP.
- Tap Download result.
PNG and WebP are also available in the same menu. Choose PNG if the AVIF has transparency you need to keep.
Why you get AVIF files
Many websites now send images as AVIF to browsers that can show them, because it's much smaller than JPG for the same picture. When you save such an image, you save the AVIF. Your browser displays it fine, but plenty of photo editors, older apps and upload forms still don't accept it. Converting to JPG makes it work everywhere.
Why the JPG is bigger: measured
AVIF is a newer, more efficient format, so the same picture takes more bytes as a JPG. We made AVIF versions of five photos and converted them back to JPG with this tool:
| Photo | AVIF | JPG, High (92%) | JPG, Good (80%) |
|---|---|---|---|
| Portrait, plain wall (26 MP) | 787 KB | 2.88 MB | 1.61 MB |
| Indoor selfie (24 MP) | 525 KB | 2.21 MB | 1.22 MB |
| Busy street market (24 MP) | 3.15 MB | 6.30 MB | 4.77 MB |
| Group photo outdoors (24 MP) | 2.69 MB | 5.86 MB | 4.22 MB |
| Clear sky, little detail (12 MP) | 121 KB | 500 KB | 187 KB |
Test photos: free-to-use Unsplash photos (12–26 megapixels; Unsplash re-encodes its downloads), saved as AVIF with Pillow (quality 60), then converted with this page's tool in desktop Chromium on our test server, October 2026. Bytes are exact; sizes in decimal units (1 MB = 1,000,000 bytes).
The JPG was about 2–4 times the AVIF's size at High (92%), and 1.5–2.3 times at Good (80%). Each conversion took about a second for a 24-megapixel image. The pixel size stays the same. Converting can't add detail the AVIF didn't have; it only changes the format.
Which quality to choose
Keep High (92%) when you'll edit or print the image: it adds the least new loss. Choose Good (80%) when the file only needs to be viewed or emailed. If a form has a size limit, convert at High first, then use compress to an exact KB on the JPG: it finds the best quality that fits the limit.
Transparency
AVIF can have transparent areas; JPG can't. Converting to JPG fills them with white. If you need to keep transparency, convert to PNG or WebP instead.
Common mistakes
- Renaming .avif to .jpg. The file is still AVIF inside, and apps and forms that check the contents will reject it. Convert it.
- Converting at a low quality "to save space". The JPG is already bigger than the AVIF; a low setting adds visible blocks. Resize or compress to a target instead.
- Expecting a better picture. Conversion keeps the image as it is; a small or blurry AVIF stays small or blurry.
Frequently asked questions
Why is the JPG bigger than the AVIF?
AVIF stores the same image more efficiently. In our tests the JPG was about 2–4 times larger at High (92%). That's normal and doesn't mean anything went wrong.
Does converting AVIF to JPG lose quality?
Very little at High (92%): the image is re-encoded once. It can't regain detail the AVIF already lost.
Can I convert several AVIF files at once?
Yes. Choose them all; they're converted with the same settings and download together as a ZIP.
What happens to transparent areas?
They become white in the JPG. Convert to PNG or WebP to keep transparency.
Can I make the JPG a specific size in KB?
Yes. Convert first, then use compress to an exact KB on the result to fit a form's limit.
Are my files uploaded?
No. Your browser decodes the AVIF and saves the JPG on your device. It also works offline once the page has loaded.
My browser can't open the AVIF. Will this work?
The converter uses your browser's own AVIF decoder. Current Chrome, Edge, Firefox and Safari all include one; very old browsers don't.
