Bulk URL Decoder
Decode many percent-encoded lines at once. Paste a list of values or URLs and decode each line.
Part of the free URL Decoder. Runs in your browser — nothing is uploaded.
Bulk URL Decoder
Log dumps and spreadsheet columns often contain one encoded value per line. Decode them in a batch so you can scan the readable results together.
Worked example: Three encoded values
Encoded
hello%20world caf%C3%A9 a%26b%3Dc
Decoded
hello world café a&b=c
Practical tip
If one line throws, the others can still decode. Isolate the bad line and check for a dangling %.

- 1Use the live tool above — it runs entirely in your browser and never uploads your data.

- 3Copy the result, then adapt the same steps in your editor, script, or pipeline.
Bulk URL Decoder FAQs
Does the decoder keep line order?
Yes. Line n of the output is the decoded form of line n of the input.
Can I decode a full access log?
You can paste request lines, but you will also decode characters that were not meant as data. Prefer extracting the URL first.
