Frequently asked questions
What Base64 input can I use?
Paste a standard Base64 string. Invalid characters or broken padding can produce a decode error.
How can I use the decoded result?
The original text appears in the result area, so you can use it like a lightweight Base64 analyzer before copying it where needed.
Is it okay to paste sensitive values?
Decoding runs in the browser, but sensitive values such as tokens or passwords may be revealed as plain text on screen.
