Frequently Asked Questions
Is Base64 a form of encryption?
No — Base64 is encoding, not encryption. It is reversible without any key and provides no security by itself.
Can it encode binary files?
This tool works with text. To encode binary files (images, PDFs), you would need a file-based Base64 tool.
