The selected input stays under your control
On-device processing means the input is handled by browser APIs on the device running this page. Closing or refreshing the page normally clears the active in-memory working session.
Read the Privacy Policy →Encode or decode URL components correctly
Handle reserved characters in query values and path components without treating encoding as encryption.
How to use it
- Paste the component or encoded value.
- Choose encode or decode.
- Copy the result and test it in its actual URL context.
Supported input
- Unicode text for component encoding
- Percent-encoded URL component text
Worked example
Encode “summer sale & offers” as a safe query parameter value before appending it to a URL.
Limitations
- Encoding a complete URL as one component can hide separators.
- Malformed percent sequences cannot be decoded reliably.
Troubleshooting
- Encode parameter values separately from ?, & and = separators.
- Avoid double-encoding existing % sequences.
Tool-specific questions
Is URL encoding secure encryption?
No, anyone can reverse percent encoding.
Why did spaces become %20?
Spaces are not literal-safe in a URL component and are percent encoded.
Before you process
Can I use this url encoder & decoder online without uploading my input?
Yes. This tool is labelled On-device, so the selected input is processed in your browser and is not sent to a ForgeMyFile processing API.
What happens if the browser cannot process it?
The tool shows a readable error and stops. It does not silently fall back to a cloud upload.
Why can performance differ between devices?
The browser is doing the work locally, so speed and practical file size depend on available memory, CPU and browser capabilities.
