Decode Base64 encoded strings
How to use

Why use this tool
- Instant decoding: Turn Base64 back into readable text the moment you paste it.

- 100% private: Everything runs in your browser. Your data is never uploaded to a server, so it's safe for confidential content.
Frequently asked questions
Why does decoding fail?
The input may not be valid Base64 — check for missing characters, spaces, or that it isn't URL-safe Base64 that needs different handling.
Can I decode a Base64 image or file?
This tool decodes Base64 text. For images, use the Base64-to-Image tool, which rebuilds the picture from the encoded string.
Is my data private?
Yes. Decoding happens entirely in your browser and nothing is uploaded.
