What is Base64?
A way to represent binary data as plain ASCII text — used in data URIs, API tokens and email attachments. Note: Base64 is encoding, not encryption; anyone can decode it.
Frequently Asked Questions
Is Base64 secure?
No — it's trivially reversible. Never use it to 'hide' passwords or secrets.
Why do APIs use Base64?
To safely embed binary data (like images) in JSON or headers.
Does it handle Unicode?
Yes — our tool UTF-8 encodes text before Base64 conversion.
