Frequently asked questions
Can this decode binary files too?
This first version is text-focused. It is intended for strings, payload snippets, and browser-side debugging rather than full file reconstruction.
What happens if the Base64 input is invalid?
The tool shows an error instead of producing broken output, so you know the source string needs to be checked first.
Does the tool send my text anywhere?
No. The encoding and decoding run in the browser.
