Convert AVIF to JPEG
We turn AVIF into JPEG right in your browser — the file never goes to a server.
What you will lose
- Transparency becomes a solid background — soft edges disappear
- Only the first frame survives
- Compression becomes lossy: the original quality cannot be restored
How they differ
| AVIF | JPEG | |
|---|---|---|
| Lossless | yes | no |
| Lossy | yes | yes |
| Transparency | yes | no |
| Animation | yes | no |

AVIF
Good at
- Compresses tighter than WebP — usually another 20–30 %
- Handles 10 bits per channel and high dynamic range
- Transparency and animation are both there
Awkward about
- Noticeably slower to encode than the others
- Support outside browsers is still thin
- On small images it sometimes loses to WebP on size
Use it when
- Large images on a site where weight matters
- When you have a fallback for older browsers
JPEG
Good at
- Compresses photos tightly, and the loss is hard to notice
- Opens literally everywhere, including old devices and printers
- Fast to encode and open, easy on the device
Awkward about
- Lossy: every re-save degrades the image a little more
- No transparency — it turns white or black
- Visible halos appear around text and sharp edges
Use it when
- Photos that will not be edited further
- When the file has to open for absolutely anyone
Common questions
- Does the file get uploaded to a server?
- No. AVIF → JPEG runs right in your browser and the file never leaves your device. It only goes to a server if the browser cannot cope — and then we delete it within a couple of hours.
- Will transparency survive?
- No. JPEG has no transparency — it becomes a solid background.
- Can I get the original quality back afterwards?
- No. JPEG is lossy, and the discarded detail cannot be recovered. Keep the original if you may still need it.
- How many files, and how large?
- Up to 30 files at a time, 50 MB each. No sign-up, no watermarks.
