File Conversion Tools
Encode special characters, query parameters, and URIs into percent-encoded format for safe web transmission.
Follow these simple steps to get instant, accurate results directly in your browser:
Type or paste the query parameter or URL snippet into the input box.
Choose Component Mode (encodes all reserved symbols) or Full URI Mode.
Click 'Copy' to grab the percent-encoded URL string.
The URL Encode tool transforms reserved characters, punctuation, spaces, and non-ASCII characters into percent-encoded hex sequences conforming to RFC 3986.
URI specifications reserve characters like ?, &, =, /, :, and # for URL routing and query syntax. When passing text parameters or JSON objects through query strings, reserved characters must be percent-encoded (e.g. space becomes %20 or +, and & becomes %26) to prevent web servers from misinterpreting the URL structure.
All encoding executes in client-side memory, allowing you to format marketing UTM tracking URLs and REST query strings securely.
Accurately converts characters into standard percent-encoded hexadecimal format.
Select between strict component encoding or full URI preservation.
Translates characters dynamically as you type with zero delay.
Parameters and URLs are processed locally with zero telemetry.
Safely encode user search queries and filter strings into URL parameters.
