Base64 to JPEG, explained
This decoder turns a Base64 image string back into a .jpeg file. JPEG (also written JPG) 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 JPEG
- Photos and gradients. JPEG compresses smoothly-shaded images far better than PNG.
- You want a smaller file. Great for web delivery and email attachments.
- Transparency isn't needed. JPEG has no alpha channel — transparent pixels become a solid background.
JPEG vs JPG
They are the same format; .jpg is simply the shorter extension. This page is
canonicalized to /base64-to-jpg so the two spellings share one strong page in search.
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.
