Frequently Asked Questions
What is Base64 encoding?
Base64 is a text representation of binary or text data that uses a limited set of ASCII characters. It is commonly used when data needs to be safely represented as text.
Can I decode Base64 with this tool?
Yes. Switch to Decode mode, paste valid Base64 data and click Decode Base64 to convert it back into readable UTF-8 text.
Does this tool support Unicode text?
Yes. The encoder uses UTF-8 so text containing many international characters and symbols can be encoded and decoded correctly.
Is Base64 encryption?
No. Base64 is an encoding format, not encryption. Base64 data can be decoded and should not be used to protect secrets or passwords.
Is my text sent to a server?
The current Base64 encoder and decoder processes entered text directly in your browser and does not need to send it to a ConvertTools processing server.
