URL Encoder & Decoder: Parse and Edit Query Parameters Visually
3 min read
•Verified Educational ResourceUnderstanding URL Encoding (Percent-Encoding)
URL encoding converts characters into a format that can be safely transmitted over the Internet. URLs can only contain a limited set of characters from the US-ASCII character set. Non-safe characters are replaced with a '%' followed by two hexadecimal digits.
For example, spaces are encoded as %20 (or + in query strings), and special characters like slashes, question marks, and ampersands must be encoded to preserve boundaries between parameters.
Query Parameter Grid Editor
Unlike traditional encoders that just output a single long percent-encoded string, this utility features a visual query parameter grid:
- Input URL Parser—Automatically splits a pasted URL into its Base Path and separate query key-value segments.
- Interactive Edit Grid—Edit, add, or delete query parameter values. Changes immediately re-encode and update the raw URL.
- Encoder / Decoder Toggle—Switch modes between encoding plain text into percent-notation or decoding percent-strings into readable strings.
- Single-Click Copy—Quickly copy the re-assembled and encoded URL to your clipboard.
