Base64 Encode / Decode
Paste-based Base64 conversion without file upload.
Result
Enter text or paste Base64.
How to use
Encode turns plain text into UTF-8 bytes, then Base64 text. Decode reverses Base64 into bytes and renders UTF-8 text—invalid padding or sequences will error.
Strip line breaks and stray spaces before decoding values copied from URLs or config files.
This UI is text-first; for large binary blobs prefer smaller chunks or a dedicated binary workflow.
