Paste text or drop a file to encode to Base64? — or paste Base64 to decode it back. URL-safe toggle included. Everything runs in your browser.
Some computer systems can only pass around plain text, so files and unusual characters get converted into a long scramble of ordinary letters and numbers first. You’ll bump into these scrambles inside email attachments, web links, and settings files.
Paste one here to turn it back into something readable, or go the other way and convert your own text or a file into that format. Everything stays on your computer.
