—About URL Encoder
The URL Encoder percent-encodes text so it can travel safely inside a URL, with a choice between encoding a single component and encoding a full URI. It is for developers building query strings, links, or redirect parameters that must survive special characters.
Spaces, ampersands, and unicode break URLs if they are not escaped. Encoding them correctly — and locally, as you type — avoids malformed links without sending your data through a remote service.
Step by step
- Type or paste the text you want to encode into the input field.
- Choose component encoding for a single value, or full-URI encoding to preserve structural characters like slashes.
- The encoded result updates live as you type.
- Copy the output for use in your link, request, or code.
What it offers
- Percent-encoding for URLs
- Component or full-URI modes
- Live updating output
- On-device encoding
Tips for best results
- Use component encoding for individual query values so slashes and ampersands inside them are escaped.
- Use full-URI encoding when you need to keep the structure of an existing address intact.
- Double-encoding is a common bug — encode a value once, not again on an already-encoded string.
Why people use it
Two modes
Component and full-URI encoding cover both query values and whole addresses.
Live output
See the encoded result update with every keystroke.
Reversible
Pair it with the decoder to confirm a value round-trips correctly.
Local
Encoding runs in the browser; nothing is transmitted.
Common questions
This runs entirely in your browser
No file or text you enter here is uploaded. Encoding and decoding happen on your device using native browser APIs — close the tab and nothing remains on a server.
