How to use the Base64 encoder
Paste UTF-8 text and choose Encode to get Base64, or paste Base64 and choose Decode to get the original text. Unicode is handled correctly. Use Copy when you are done.
Frequently asked questions
What is Base64 encoding?
Base64 represents bytes as ASCII using A–Z, a–z, 0–9, and a few symbols. It is meant for transport, not secrecy.
Can I decode Base64 back to text?
Yes. Decode converts valid Base64 back into UTF-8 text. If the input is not valid Base64, you get an error instead of silent corruption.
Is my text uploaded or stored?
No. All encoding and decoding happens in your browser. Deskutil never receives the content.
Why do I see an invalid Base64 error?
The string could not be decoded. Remove unexpected characters, fix padding, and make sure you pasted Base64 rather than ordinary text.
