What this tool does
Encodes or decodes URL components (percent-encoding) to make query strings and paths safe.
This page focuses on practical, step‑by‑step usage for **URL Encoder / Decoder**, with clear examples and common pitfalls.
When you should use it
Use it when debugging web requests, APIs, redirects, or tracking parameters.
How to use
- Paste the URL or component.
- Choose Encode or Decode.
- Verify spaces, plus signs, and reserved characters.
Quick example
Example: Decode a query string to reveal nested parameters, then re-encode after editing.
Notes
Encode only components (like a parameter value), not the entire URL unless you know you need that.
URL Encoder / Decoder
Encode text for URL safety or decode URL-encoded strings back to original text.
About URL Encoding
URL encoding converts characters into a format that can be transmitted over the Internet. URLs can only be sent over the Internet using the ASCII character-set.
Common Use Cases
- URL parameter encoding
- Form data submission
- API request parameters
- Special character handling in URLs
- Cross-site scripting prevention
Commonly Encoded Characters
- Space →
%20or+ - Ampersand (&) →
%26 - Equals (=) →
%3D - Question Mark (?) →
%3F - Slash (/) →
%2F - Percent (%) →
%25
FAQ
What’s the difference between encoding and encryption on this page?
Encoding changes representation (for transport/compatibility). Encryption protects confidentiality with a key. Use encryption when you need secrecy.
What should I do if the input fails to decode/parse?
Start by checking for missing padding, wrong alphabet/variant, or extra whitespace. If the data looks multi-layered, try decoding step-by-step (e.g., URL decode → Base64 decode).
Is it safe to paste sensitive data here?
For best security, avoid pasting real secrets (private keys, live tokens, seed phrases). Use test data or work offline, especially for anything that could grant access or move funds.
