Frequently asked questions
What is Base64?
Base64 is a way of representing binary or text data using 64 printable characters. It is used in emails, JSON, images and URLs.
Is Base64 encryption?
No — it is just an encoding. Anyone can decode it, so never treat Base64 as a way to secure passwords.
Can I convert Base64 to text?
Yes. Paste the Base64 string and click Decode to get the original text.
Why does my Base64 fail to decode?
It may be truncated or contain invalid characters. The tool reports the exact problem instead of failing silently.
