What Is a URL Encoder/Decoder?
URL encoding converts spaces and special characters into percent-encoded values so they can safely travel inside URLs and query strings.
How It Works
Paste your text or a URL fragment, then choose Encode or Decode. The tool converts the entire input and shows a clean result instantly.
Benefits
- Safe query strings for APIs and search links
- Quick decoding of tracking and log URLs
- Private processing directly in your browser
Common Use Cases
- Encoding UTM parameters or search values
- Decoding percent-encoded paths from logs
- Cleaning strings before building request URLs
Frequently Asked Questions
Does encoding change the meaning of the URL? No. It only converts special characters to a safe format.
Why do I see %20 in my URLs? %20 is the encoded form of a space.
Is my data uploaded? No. Everything runs locally in your browser.
Should I paste a full URL? This tool encodes the entire input, so encode only the part you need.

Encode only the part you need
Most of the time, you should encode just the query value, not the full URL. For example, encode a search term or UTM value and then attach it to the rest of the URL unchanged.
Reserved characters and common encodings
Spaces become %20, slashes become %2F, and question marks become %3F when encoded. These conversions prevent URLs from breaking when user input contains special characters.
Useful pairings
If you are sharing links with QR codes, use this tool with the QR Code Generator. For payloads inside links, the Base64 Encoder/Decoder can help format data safely.
