? Frequently Asked Questions
What is URL encoding?
URL encoding (percent-encoding) converts special characters into %XX format where XX is hexadecimal. For example, space becomes %20, & becomes %26. This ensures URLs work correctly across all systems and browsers.
Which characters need URL encoding?
Characters outside A-Z, a-z, 0-9, and unreserved characters (- _ . ~) should be encoded. This includes spaces, &, ?, =, /, #, and non-ASCII characters like accented letters and emojis.
What's the difference between URL encoding and HTML encoding?
URL encoding uses % notation for URLs (%20 for space), while HTML encoding uses & entities for HTML content (& for &). They serve different purposes and use different formats.
Can I encode entire URLs or just parts?
Encode only query parameters and path segments, not the entire URL. For example, encode the value in '?search=my value' to '?search=my%20value', but keep the protocol and domain as-is.
Does it handle international characters?
Yes! The encoder converts Unicode characters (Chinese, Arabic, emoji, etc.) to percent-encoded UTF-8 sequences. For example, '你好' becomes '%E4%BD%A0%E5%A5%BD', ensuring proper URL transmission.
