What is AVIF?
AVIF (AV1 Image File Format) is a modern image codec built on AV1 video compression. It often produces smaller files than JPEG or WebP at similar visual quality, supports HDR and transparency, and is widely used for performance-minded websites. You will see .avif files from CDNs, modern export presets, and some phone or camera workflows.
Why convert AVIF to JPG? Many desktop apps, email clients, print services, and legacy upload forms still expect JPEG. Converting gives you a universally accepted file — at the cost of larger size versus AVIF, which is normal.
Why your browser saves images as .avif instead of .jpg
When you right-click an image on a modern website and choose Save Image As, your browser saves the file your browser actually downloaded — and on performance-optimized sites, that file may now be a .avif, not a .jpg or even .webp.
Your browser does not choose this format. The website's server picks it. When your browser requests an image, it sends an Accept HTTP header listing which formats it supports. If AVIF is on the list and the server has an AVIF version of the image, the server sends AVIF because it is typically the smallest of the modern formats — often smaller than WebP, much smaller than JPG. You receive an AVIF file and your browser saves it with the .avif extension.
This is excellent for page-load performance but inconvenient when you need the image in a tool that does not understand AVIF yet — older Photoshop versions, email clients, print labs, or upload forms restricted to JPG and PNG. Three options:
- Convert it. Use this AVIF to JPG converter — drop the file, get a JPG back.
- Use a screenshot. Crop and screenshot the image; the screenshot is saved in your OS's default format (usually PNG).
- Try a different download path. Some sites offer a "download original" link that bypasses the AVIF optimization.
Conversion is the most reliable option for maintaining image quality. AVIF is harder to handle than WebP because adoption is newer — many tools added WebP support years ago but still don't recognize AVIF.
How this converter works
Your browser must decode AVIF natively. The tool uses createImageBitmap when available, otherwise an Image element, then draws pixels to a canvas and calls toBlob('image/jpeg') at your selected quality. No WASM decoder and no upload — if the browser cannot decode AVIF, conversion cannot proceed on that device.
- Add AVIF files. Drop or browse; batch many at once.
- Choose JPEG quality. Open Advanced options: Maximum (100%), Balanced (85%), or Small file (70%).
- Download. Individual JPGs or Download All as ZIP.
For other next-gen formats, see WebP to JPG. For Apple HEIC photos, use HEIC to JPG.
AVIF vs JPG
| Aspect | AVIF | JPG |
|---|---|---|
| Typical file size | Often smallest for photos | Larger at equal quality |
| Compatibility | Strong in modern browsers; weaker in some desktop apps | Universal |
| Transparency | Yes | No |
| Best for | Web delivery, Core Web Vitals | Sharing, email, print, legacy tools |

Transparency and white background
JPEG has no alpha channel. This tool fills the canvas with white before drawing the decoded AVIF, so transparent regions appear on white in the output — the same approach as our WebP to JPG tool.
Who converts AVIF to JPEG?
- Developers and designers handing assets to clients who only accept JPG.
- Content creators submitting images to platforms without AVIF upload.
- Anyone who received or downloaded AVIF and needs a familiar .jpg file.
Troubleshooting
“AVIF not supported in this browser”: Update Chrome, Edge, Firefox, or Safari, or try another device. This page does not bundle a separate AVIF decoder.
Huge JPG vs tiny AVIF: Expected — JPEG is less efficient; use a lower quality preset only if you accept more compression artifacts.
Need smaller JPG without changing format first: After export, use our image compressor on the JPG if your pipeline allows another step.
