About this tool
Base64 turns bytes into plain letters and digits so they can travel through email, JSON, URLs and HTTP headers. Text is first converted to UTF-8, so Hindi, emoji and accented letters round-trip correctly, unlike the browser's basic btoa function, which fails on them.
Decoding accepts standard and URL-safe Base64 (with - and _), with or without = padding and line breaks. If the Base64 contains binary data such as an image rather than text, the tool says so instead of showing garbage. Remember: Base64 is an encoding, not encryption; anyone can decode it.
Everything runs in your browser. Your text is never uploaded or stored, so it is safe for drafts, code and private documents.

Questions
Is Base64 encryption?
No. It's a reversible encoding anyone can decode. Never use it to hide passwords or secrets.
What is URL-safe Base64?
A variant that uses - and _ instead of + and / and drops the = padding, so the result can sit in a URL or filename. It's common in JWTs.
Why does decoding say it's binary data?
The decoded bytes aren't valid UTF-8 text, which usually means the Base64 holds an image, PDF or other file rather than text.
