Frequently Asked Questions

Does this upload my text anywhere?
No — encoding and decoding happen entirely in your browser.
What is Base64 used for?
Base64 encodes binary or text data into a safe ASCII string format, commonly used for embedding data in URLs, JSON, or email attachments where raw binary isn't allowed.
Is Base64 encryption?
No — Base64 is an encoding, not encryption. It's trivially reversible and provides no security or confidentiality; don't use it to protect sensitive data.
