URL Encoder / Decoder
Pasting a URL with spaces or special characters often breaks sharing or API requests. If you are struggling with broken links, our url encoder decoder online is the easiest way to safely prepare paths for the web. It is completely free with no signup required.
What Is a URL Encoder / Decoder?
This online tool converts text into a percent-encoded format so that web servers can read it correctly. It also lets you decode url online entries back into human-readable text. It handles spaces, punctuation, and Unicode characters in seconds.
How to Use the Online Encoder and Decoder
- Paste your plain text or encoded URL into the Input box.
- Select either the 'Encode' or 'Decode' mode from the top tabs.
- If you want to keep characters like / and ? intact, click 'Encode URI (keep /)'.
- Copy the instantly transformed output to your clipboard with a single click.
- Use the swap button if you need to feed the output back into the input for further processing.
How URL Encoding Works
Under the hood, the browser translates non-alphanumeric characters into their hexadecimal ASCII value and prefixes them with a percent sign (%). Characters like letters, numbers, and selected symbols (- _ . ~) remain untouched. Let's look at a quick real-number example: the space character has an ASCII decimal value of 32, which is 20 in hexadecimal. Therefore, a space becomes %20 when you url encode it. Another common example is the character '&', which translates to %26.

URL Encoding vs URL Decoding
| Aspect | URL Encoding | URL Decoding |
|---|---|---|
| Primary Purpose | Converts special/unsafe characters to percent format | Restores percent-encoded characters back to plain text |
| Conversion Flow | Plain text/URL ➔ %-encoded string | %-encoded string ➔ Readable text/URL |
| Real-World Example | (space) becomes %20 | %20 becomes (space) |
| Typical Use Case | Building API queries, encoding parameter values safely | Reading logged parameters, debugging server redirects |
| JavaScript Functions | encodeURIComponent(), encodeURI() | decodeURIComponent(), decodeURI() |
Who Is This For?
- Web Developers: Quickly format query parameters for API calls or inspect percent-encoded redirects.
- SEO Specialists: Clean up URL structures and remove invalid characters to optimize search rankings.
- Content Editors: Convert special characters in articles or decode links copied from social media platforms.
- Security Researchers: Decode obfuscated payloads or verify URL parameters during analysis.
Pro Tips for URL Encoding & Decoding
- Use 'Encode URI' if you are pasting a full URL. This prevents characters like 'http://' or query symbols from turning into unreadable code.
- Double-check for spaces before encoding. Pinned parameters with spaces can cause unexpected 400 Bad Request responses from servers.
- Use the swap feature to decode a string, modify the raw text, and encode it back without copying and pasting twice.
- Bookmarking Toolsnak lets you pull up the page instantly during live calls or debugging sessions.
Common Mistakes to Avoid
- Double Encoding: Encoding an already encoded URL creates broken strings like %2520 instead of %20.
- Encoding Full URLs as Components: Using encodeURIComponent on a full address turns slashes into %2F, breaking the link.
- Copying Whitespace: Accidentally including a trailing space or newline character, which transforms into %20 or %0A.
