URL Strings Formatting Explained
URLs can only be sent over the Internet using the US-ASCII character set. Since URLs often contain characters outside the ASCII set (like international characters, blank spaces, or special symbols like `&` and `?`), the URL has to be converted into a valid ASCII format. The free online **URL Encoder** perfectly sanitizes these bad actors.
Why is Encoding Necessary?
- Transport Safety: Replaces unsafe URL characters with a "%" followed by two hexadecimal digits. The most common instance is swapping space-bars with `%20`.
- Query Parameters: Crucial for transmitting strings containing equals `=` or ampersands `&` inside a form or API GET request without confusing the receiving server router.
- Shareable Links: Whenever creating deep links (like WhatsApp pre-filled chat messages), you must encode the drafted message to guarantee delivery.
