Decoding runs entirely in your browser using atob + Image. Your Base64 input is never uploaded to any server.
FAQ
- Does my Base64 text get uploaded?
- No. Decoding happens entirely in your browser via atob + the built-in Image element. No network requests are made.
- Can I paste a data-URI prefix?
- Yes. The decoder accepts both `data:image/png;base64,…` and a plain Base64 string. If the prefix is missing, PNG is assumed by default.
- Why is my image showing as broken?
- The most common cause is a truncated or corrupted Base64 string. Paste it again in one piece — even a missing character at the end will invalidate the output.
