Base64 to JPG, explained
This decoder turns a Base64 image string back into a .jpg file. JPG (or JPEG) is a lossy format that shrinks file size dramatically, which makes it the right choice for photographs and complex images where a little quality loss is invisible to the eye.
When to choose JPG
- Photos and gradients. JPG compresses smoothly-shaded images far better than PNG.
- You want a smaller file. Great for web delivery and email attachments.
- Transparency isn't needed. JPG has no alpha channel — transparent pixels become a solid background.
What you can paste
- A full data URI —
data:image/jpeg;base64,/9j/4AAQ.... Names the exact format, most reliable. - A bare Base64 body — decoded and saved as a JPG.
Private by design
Decoding uses the browser's native image handling — the string is turned into an image element locally and never sent anywhere. Safe for confidential assets.

How do I convert a Base64 string to a JPG?
Paste the Base64 string or full data URI into the box and click Decode to JPG. The image renders instantly and you can download it as a .jpg file.
Does JPG keep transparency?
No. JPG has no alpha channel, so any transparent areas are filled with a solid background (usually white) in the saved file. Use PNG if you need transparency.
