A LITTLE GUIDANCE
How to use Base64 encoder & decoder
Select encode or decode, enter your text and run the conversion. Unicode text is encoded using UTF-8.
Good to know
Base64 is encoding, not encryption. The decoder accepts standard Base64, not arbitrary binary files.
A few quick answers.
Does Base64 encrypt my text?
No. Base64 is a reversible encoding, not encryption. Text is encoded as UTF-8; decoding rejects byte sequences that are not valid UTF-8 text.
Is my input sent to a server?
No. This tool processes your input in your browser. We don't store your text, files or results. Standard website access logs are separate; read our privacy notes.
Can I use it for free?
Yes. No account, subscription or usage credits are required.
How do I keep my result?
Use Copy or Download after running the tool. Inputs are not saved automatically and disappear when you leave or refresh the page.
