URL Decoder Online

Updated 2026-08-19

Decode percent-encoded URLs and strings online, instantly and privately in your browser. Paste text full of "%XX" codes and SnapTools restores the original characters as you type, turning escaped query strings and parameters back into readable form. Nothing is uploaded; decoding runs locally, so it's safe for private data.

Logs, redirects, and API URLs are littered with sequences like "%20", "%26", and "%3D" that are hard to read at a glance. URL decoding maps each one back to its real character. It's a reversible transform, not encryption, so decoding simply reveals what was always there.

// how to use

  1. 1 Paste the percent-encoded string into the input panel on the left.
  2. 2 SnapTools decodes the "%XX" sequences back to characters as you type.
  3. 3 Read the readable result in the output panel on the right.
  4. 4 Use Copy or Download to save the decoded text.

// faq

Is my text sent to a server?
No. Decoding happens entirely in your browser, so nothing is uploaded and your input stays on your machine.
Is URL decoding related to encryption?
No. Percent-encoding is a reversible transform with no security — decoding just restores the original characters. It was never encrypted, so nothing is being "cracked".
What does "%20" mean?
It's the percent-encoded form of a space. Each "%XX" pair is the hex code for one character — "%26" is "&", "%3D" is "=", and so on — and the decoder turns them back into the real characters.
What is the difference between this and a Base64 decoder?
URL decoding only reverses "%XX" escapes in a URL string. A Base64 decoder reverses the entirely different Base64 alphabet. Pick the one that matches how the value was encoded.
Why do I see "+" turn into a space?
In query strings the "+" is often used for a space. Standard percent-decoding may keep "+" literal, so check the source if a value looks slightly off.
