Base64 Encoder & Decoder
Text to Base64 and back, in any language, with the URL-safe alphabet when you need it.
Percent-encode a link or one value, decode one back, and read what a long link carries.
Encode a link so spaces and Bangla text survive being pasted into a message, or decode one that arrived full of %20 and %E0. Whole links and single values are handled differently, as they should be, and the query string is broken out into rows so you can see what a long tracking link is actually carrying.
A whole link keeps the characters that give it structure, the : / ? & and #, so it still works. One value escapes those too, which is what you want when the value itself contains an & or a ? that would otherwise be read as part of the link.
Percent-encoding carries bytes, not letters. If the text was encoded in something other than UTF-8, the bytes decode to different characters. Everything encoded by this page, and by browsers today, is UTF-8.
No. The tool runs in this browser tab. What you paste is never sent to KuponGuru, and it is gone when you close the tab.
