Queryfold

Local query inspection · ordered pairs

See what the query actually contains.

Keep repeated keys, empty values and original token spelling together. Inspect a query portion without visiting its destination.

Paste the query portion

Paste the part after a URL’s first question mark, with one optional leading ?. This is not a full-URL parser. Literal # and an extra ? are data. Unicode must use UTF-8 percent bytes; raw tabs and line breaks are rejected.

Why an ordered list helps

tag=blue&tag=green contains two pairs. Converting it directly to an object can hide one value. Queryfold keeps both, and preserves whether an equals sign appeared, so flag and flag= can be compared without losing that raw distinction.

This tool does not decide which value a particular server will use, remove tracking parameters or assess whether a link is safe. The worked examples show the selected decoding rules.
