About URL Decoder
Small text transformations show up constantly in coding and writing workflows. URL Decoder is built for that job: decode percent-encoded URL strings and query values (%20, %2F, UTF-8 sequences) back into readable text in your browser.
What URL Decoder does
Decode percent-encoded URL strings and query values (%20, %2F, UTF-8 sequences) back into readable text in your browser. Paste only the segment you need so results stay easy to scan. For encoding tools, round-trip with the matching encode/decode pair when you want to verify.
Tips for accurate url decoder results
Watch for whitespace, wrapping quotes, and character set issues. If the tool errors, simplify the input and retry. Use related utilities below when your workflow needs a second transform.
Where your data goes
URL Decoder runs in your browser for this job. Your text input is not uploaded to FileToolsHub servers for the conversion itself, which matters when you are dealing with private notes, drafts, or local files.
How to use
- 1
Paste a percent-encoded string, full URL, or query fragment into the input.
- 2
Click decode — FileToolsHub runs decodeURIComponent locally in your browser.
- 3
Copy the readable result; re-run if the value was double-encoded.
Privacy
Runs entirely in your browser — your text input is not uploaded.
Frequently asked questions
When do I need a URL decoder?
Whenever you receive a callback, log line, or spreadsheet cell full of %20 / %2F / %3A sequences and need the human-readable path or query value.
How are spaces and plus signs handled?
Percent-encoded spaces (%20) decode to spaces. Some form encodings use + for spaces — if a plus remains literal, replace + with %20 and decode again, or decode the query with application/x-www-form-urlencoded rules in your app.
Is URL Decoder free?
Yes. URL Decoder is free for everyday use with no account required, and it runs in your browser.
Does URL Decoder upload my data?
No. URL Decoder processes your text input locally in this tab.

How are spaces and plus signs handled?
Percent-encoded spaces (%20) decode to spaces. Some form encodings use + for spaces — if a plus remains literal, replace + with %20 and decode again, or decode the query with application/x-www-form-urlencoded rules in your app.
What about double encoding?
If you still see %25 sequences after one pass, the value was encoded twice. Run URL Decoder again until the text stabilizes.
Is my string uploaded?
No. URL Decoder is a browser-side text tool on FileToolsHub — nothing is sent to the server.
