URL Encoder / Decoder
URL-encode special characters for safe use in query strings, or decode percent-encoded URLs back to readable text.

What is URL encoding?
URL encoding (percent-encoding) replaces unsafe characters with a % sign followed by two hex digits. Spaces become %20 or +, & becomes %26, and so on. It is required whenever special characters appear in query string values.
Why use Encoder/Decoder online?
Encoder/Decoder in the browser saves context switching: no CLI install, no fragile one-liners, and instant feedback for teammates who do not live in the terminal. It is ideal for debugging, demos, and quick checks during code review.
Tips for best results
Work with a sample payload first, then paste production data. Keep privacy in mind: prefer local browser processing for secrets, tokens, and customer data. Bookmark this page for faster access next time.
How to use
- To encode: type or paste text in the top input — the encoded output updates live.
- To decode: type or paste a percent-encoded string in the bottom input — the decoded text updates live.
- Review the output and use Copy to paste into your editor, ticket, or chat.

- Double-check results before using them in production — especially for security-sensitive data.
Online tool vs terminal
| Terminal / CLI | This tool |
|---|---|
| Install CLI tools or write a one-off script | Open the tool in your browser — no install |
| Look up flags in man pages or Stack Overflow | Paste input or upload files where supported |
| Repeat for each file format or edge case | Get instant visual feedback and copy buttons |
All encoding happens in your browser — nothing is sent to any server.
Frequently Asked Questions
- What does Encoder/Decoder do?
- URL-encode special characters for safe use in query strings, or decode percent-encoded URLs back to readable text.
- What is the difference between encodeURI and encodeURIComponent?
- encodeURI encodes a full URL, leaving characters like /, ?, # intact. encodeURIComponent encodes a single URI component (a query value), encoding those characters too. This tool uses encodeURIComponent for maximum safety.
- Is this tool free?
- Yes, completely free with no sign-up.
- Is this tool free to use?
- Yes. All Skybin developer tools are free with no account, API key, or usage limits.
- Does my data get sent to a server?
- No. Processing runs in your browser whenever possible. Sensitive input never leaves your device unless a tool explicitly fetches a URL you provide (e.g. OG Validator).
- Can I use this on mobile?
- Yes. The tools work in modern mobile browsers, though a desktop screen is easier for large JSON or PDF workflows.
- How is this different from desktop apps?
- There is nothing to install or update. Open a bookmarked URL and start working — ideal for quick tasks during development or support calls.
- Are there keyboard shortcuts?
- Most tools support standard paste (Ctrl+V / Cmd+V) and select-all in text areas. Copy buttons provide one-click output.
- Does Skybin store my history?
- No. We do not log tool inputs or outputs. Refreshing the page clears in-memory state unless the tool encodes state in the URL.
