Best Free Online URL Decoder
Percent-encoded URLs are deliberately designed to be unambiguous for machines, but they're hard for humans to read. A URL containing query parameters, Unicode path segments, or redirect targets can become a long string of %XX sequences that obscures what's actually being requested. devtoolkit.sh's URL Decoder converts percent-encoded strings back to their readable original form immediately. This is useful for inspecting redirect chains, reading encoded query parameters in logs and analytics reports, decoding URLs embedded in other URLs (double-encoded redirects), and understanding what a link actually points to before clicking it. The decoder correctly handles UTF-8 multi-byte sequences, so encoded non-Latin characters and emoji are decoded back to their original glyphs. Both standard (%20 for space) and plus-encoded (+ for space, used in form submissions) formats are supported. All decoding happens in your browser with no server involvement. It also makes reviewing analytics tracking URLs and ad campaign parameters straightforward, replacing unreadable %XX strings with the actual UTM values and query keys.
FAQ
- What is URL decoding?
- URL decoding converts percent-encoded characters (%XX sequences) back to their original form, making encoded URLs readable again.
- What is the difference between %20 and + for spaces?
- %20 is standard percent-encoding for space. A + sign is used to represent space in application/x-www-form-urlencoded data (HTML form submissions). Both are decoded to a space character.
- Can it decode doubly-encoded URLs?
- Yes. Paste the encoded string and click decode. If it was double-encoded, decode twice to get the original.
