About Base64 Encode
Base64 Encode turns any file you upload into a .txt file with its Base64 string, without line breaks or a data: prefix. The encoded text is about a third larger than the file.
Frequently asked questions
Is base64 encryption?
No. It's a reversible encoding that anyone can decode. Use base64 for transport, not secrecy.
Does it work for binary files?
Yes. Drop a file and the tool returns the file's bytes encoded as base64.
