Frequently Asked Questions

What is URL encoding?
URL encoding, also called percent - encoding, converts special characters into a safe format for URLs and query strings.
When should I use URL encoding?
Use it when passing text through query parameters, redirects, forms, or API requests that expect URL - safe values.
Is my data sent to your servers?
No. Encoding and decoding happen locally in your browser.
Does this handle international characters?
Yes. UTF - 8 characters such as Korean, Japanese, emoji, and other non - ASCII text are supported.
Should I encode an entire URL?
Usually no. In most cases you only encode parameter values, not the whole URL structure.
What is the difference between URL encoding and Base64?
URL encoding makes text safe for URLs. Base64 is a different encoding scheme for representing binary or text data.
Does this work offline?
Yes. Once the page has loaded, the conversion happens in the browser without sending data anywhere.
Why would I use query - string mode?
Some systems expect spaces to be represented as + instead of %20 when working with form - style query values.
