  2. Type/paste text, or drop a file to encode.
  3. Toggle URL-safe if needed and copy the result.

Frequently asked questions

What is URL-safe Base64?
A variant that replaces + and / with - and _ and drops padding, so the string is safe to put in URLs.
Can I Base64-encode an image?
Yes — drop the file in and it is encoded locally; the bytes never leave your browser.
