URL Encoder Online
Encode spaces, Unicode, and reserved characters for query strings and path segments. Encoding is local so tokens in the URL are not posted anywhere.
How to use URL Encoder
Drop the text, table, or snippet that needs url encoder into the input box.
Toggle the checkboxes or fields if the tool offers them, then watch the output update.
Use Copy or Save. Because this runs locally, you can work on private data without an account.
Why use this tool?
The Problem
Unescaped spaces and ampersands split query strings and break tracking links or API calls.
The Solution
This encoder applies percent-encoding so the value can sit safely in a URL.
Common Use Cases
- Build search URLs
- Escape UTM values
- Prepare API query params
How it works
encodeURIComponent-style escaping replaces unsafe characters with %HH sequences. All calculations and text processing routines execute locally using standard JavaScript inside your browser. No contents are uploaded to any server.
Before / After Example
hello world & friends
hello%20world%20%26%20friends
Tips & Best Practices
Encode query values, not the entire URL including https:// — encoding the scheme will break the link.
Common Mistakes
Double-encoding (%2520) happens if you encode an already-encoded string. Decode first if you see stacked percents.
Frequently Asked Questions
How do I use URL Encoder online?
Paste your input into URL Encoder, adjust any options, and copy the result. Escape URL strings into percent codes. All processing stays in the tab.
Does URL Encoder upload my data?
No. URL Encoder runs in your browser with JavaScript. Answer to Geek does not receive the text, CSV, tokens, or files you paste.
Should I encode the whole URL or just the query?
Usually just the values. Encoding https:// as well produces a string that browsers will not open. Use URL Parser if you need to split parts first.
