Frequently Asked Questions
What is Base64 encoding?
Base64 is a way of encoding binary data (or text) into a string of ASCII characters. It's commonly used in emails, URLs, and APIs to safely transmit data.
Is this Base64 tool free?
Yes, completely free. No signup, no limits. Everything runs in your browser.
Is my data private?
Yes. Your data never leaves your browser. Nothing is sent to any server.
Does Base64 encrypt my data?
No. Base64 is an encoding, not encryption. Anyone can decode it. It's meant for data transport, not security.
Can I encode special characters and emoji?
Yes. This tool handles Unicode text including special characters, accented letters, and emoji by encoding as UTF-8 before Base64 conversion.
