Decode percent escapes back into their UTF-8 text characters. Follow the exact input and settings below to reproduce this example. Open URL Decode.
Prepare the source text
Open URL Decode and choose Write or paste text, or upload a supported UTF-8 text file. The upload opens the editor; it does not run the tool. This example uses the exact source shown in the comparison.
Maximum input and result: 1 MB of UTF-8 text, with a 1,048,576-character input ceiling. Expanding transformations must also fit the result limit.
Use the exact example input
hello%20world%20%26%20more
This text operation runs in your browser; its source and result are not sent for conversion. A draft may be kept in this browser tab when session storage is available. Clear removes the current draft; download important work before closing the tab.
Check how the tool works
This tool has no extra transformation options to set. Keep the source exactly as shown to compare the result.
Percent escapes are interpreted as UTF-8 bytes and decoded as one component. For example, %20 becomes a space. Literal plus signs stay plus signs. An incomplete escape or invalid UTF-8 sequence is rejected instead of being silently repaired.

- Saved result
- 18 bytes
Apply and inspect the result
Select URL Decode when the input and settings are ready. In the saved example, the result begins: "hello world & more".
Form-style encoding sometimes uses + for a space. Replace those plus signs separately only when you know that convention was used.
Check the decoded component in the monospaced result and compare input and result UTF-8 byte sizes in Result overview. If an escape is incomplete or the bytes are not valid UTF-8, correct the source and run the tool again.
Result overview distinguishes changed, unchanged and empty results. An unchanged result means the selected operation did not alter the text; an empty result can be the expected outcome of removal or extraction. Open Show spaces and tabs to reveal spaces as ·, tabs as ⇥ and line endings as ↵. These marks are only a preview; copied and downloaded text keeps its actual whitespace. The whitespace preview shows at most 12,000 Unicode code points. This preview limit does not shorten the editable result or its TXT download.
Save the version you reviewed
Review the current result, then use the download icon to save a TXT file. The actual download in this example is named url-decode.txt. Copy and download use the current result, so make any final wording changes before saving. Continue to can carry the result into a compatible next tool, where you review it before running another operation.
Editing the result hides the calculated details until you run the tool again. Copy and TXT download use the edited text; return to the source and reapply the tool to refresh the report.

Common questions
Which settings produced this example?
No extra transformation settings were required. The source and actual output are shown in the comparison.
What should I check before using the result?
Form-style encoding sometimes uses + for a space. Replace those plus signs separately only when you know that convention was used.
Where is this text processed?
