Convert Integers to URL Encoding

The Convert Integers to URL Encoding tool lets you instantly turn numbers into their URL-safe hexadecimal codes like turning 32 into %20. It’s a simple way to encode characters from ASCII values and prep integer lists for use in query strings, encoding pipelines, or debugging tasks. Works live in your browser and doesn’t upload anything.

Paste your input above or import a file below.
No file chosen
Supported file types: .txt, .csv, .tsv, .log, .json, .xml, .md, .ini, .yaml, .yml, .html, .htm, .css
Total items: 0
Options
Ignore non-integers
Remove duplicates
Maximize output

How to Use:

  • Paste your integers into the input box one per line, spaced, or however you like.
  • Or use Choose File to import from a supported text file (.txt, .csv, etc.).
  • Use the Options box to toggle:
    • Ignore non-integers – filters out anything that’s not a valid number.
    • Remove duplicates – only keeps one of each encoded result.
    • Maximize output – expands the output box for long results.
  • Output updates live as you type or change toggles.
  • Use Copy Output to grab the encoded results.
  • Use Export to File to save them.
  • Click Clear All to reset everything.

What Convert Integers to URL Encoding can do:

This tool flips any integer into its URL-encoded hex value. If you feed it 32, you’ll get %20, which is the encoded space character. It supports a wide range of input styles, and you can trim down your results with the ignore-invalid and dedupe options. Everything runs right in the browser no network, no lag.

You can use this to test encoding issues, generate ASCII character maps, or convert raw numerical data into something URL-safe. It’s a dead simple way to bridge integers and encoding.

Example:

Input:

32
65
-12
hello
65

Output (with ignore + dedupe):

%20
%41

Common Use Cases:

If you’re working with ASCII values and want to turn them into something you can use in a URL this is your tool. It’s also helpful when debugging encoded URLs, encoding query strings by character code, or generating quick lookups. Developers, QA testers, and data wranglers will all find this useful.
