How it works

Base64 encodes binary as ASCII (A-Z, a-z, 0-9, +, /). URL-safe swaps `+→-`, `/→_`, strips `=`. Decoding reverses it. All in browser via TextEncoder + btoa/atob — no upload.

Frequently Asked Questions

URL-safe?: For JWT/URLs. Encoded without + / = padding. Decoding auto-handles both.
File?: Upload any file — we read as text and encode. For binary, we base64 the bytes.
Private?: Yes — runs locally. We track only copy/download clicks, never content.
