About Base64 Encode
Encode text or a file to base64 so it can travel inside JSON, HTTP headers, or environment variables without escaping issues. The encoded output is roughly 33 percent larger than the input.
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.
