How to use URL-encode a List
- 1. Paste your list. Put one item per line into the input pane, such as search terms or labels that contain spaces, ampersands, or other characters unsafe in a URL.
- 2. Decide how to encode spaces. Turn on Encode spaces as + to use the traditional query-string convention, or leave it off to encode spaces as %20 as in a URL path segment.
- 3. Copy the percent-encoded list. Copy the result, with special characters replaced by percent-escape sequences and line breaks turned into %0A, into a URL or query string.
When to use URL-encode a List
URL-encode a List percent-escapes every item in a list so it can safely travel inside a URL, replacing spaces, ampersands, and other reserved characters with their encoded form. Use URL-encode a List whenever list values need to become part of a link or query string.
- Building a shareable link with multiple search terms. You want to pre-fill a search page with several terms passed through the URL. Encode the list of terms so spaces and special characters do not break the link.
- Passing a list of tags through a query string. An app reads filter tags from the URL and some tags contain spaces or ampersands. Encode the tag list before appending it as a query parameter.
- Preparing form data for a manual GET request. You are constructing a GET request by hand for testing and need list values embedded safely in the URL. Percent-encode the list before assembling the final request.
- Sharing a bookmark that encodes several values. You built a bookmarklet or shortcut URL that needs several list values packed into one parameter. Encode the list to make sure every character survives the URL correctly.
Examples
Percent-escape items
Input
hello world foo&bar
Output
hello%20world%0Afoo%26bar
About the URL-encode a List tool
URL-encode a List runs as plain JavaScript in your browser tab, with no server behind it. Convert list to URL encoding. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's List Tools section, 114 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with the Encode spaces as + setting, and the result refreshes the moment you change it. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
Frequently asked questions
Does URL-encode a List cost anything?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
No data leaves your device. The whole tool is JavaScript that runs inside your browser tab, so there is no upload, no server-side processing and no log of what you did. If you disconnect from the internet after the page loads, it keeps working.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
Nothing to install and no account needed. Open the page in any up-to-date browser, including on a phone or tablet, and the tool is ready.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
