Frequently Asked Questions
What is Base64?
Base64 is a way to represent binary data (like images or files) as transferable text; it is common in email, data URIs and tokens.
Is Base64 encryption?
No. Base64 is only an encoding and is trivially reversible; it provides no security and must not be relied on to hide sensitive data.
What is the difference between Base64 and Base64URL?
Base64URL replaces + and / with - and _ so it is safe in URLs and file names; the option for it is available in this tool.
