❓ Frequently Asked Questions

What is URL encoding and when do I need it? +
URL encoding (also called percent-encoding) converts special characters into a format that can be safely transmitted over the internet. You need it when URLs contain spaces, special characters (@, #, %, etc.), or international characters. For example, "hello world" becomes "hello%20world" so it can be properly processed by web servers and browsers.
What's the difference between URL encoding and URI component encoding? +
URL encoding preserves certain characters like slashes (/) and colons (:) that are part of the URL structure, while URI component encoding treats these as special characters to be encoded. Use URI component encoding for query parameters and form data, and standard URL encoding for complete URLs.
Why do some characters become multiple percent signs? +
International characters and emojis use UTF-8 encoding, which can require multiple bytes. For example, "café" becomes "caf%C3%A9" because the "é" character requires two bytes (%C3%A9) in UTF-8. This is normal and ensures proper display across all systems and languages.
Can I decode URLs that are already partially encoded? +
Yes, the decoder can handle partially encoded URLs and mixed content. It will only decode the percent-encoded portions while leaving normal characters unchanged. However, be careful not to double-encode URLs, as this can cause issues with web applications.
Is it safe to use this tool with sensitive URLs or data? +
Yes, this tool processes everything locally in your browser - no data is sent to external servers. However, avoid encoding/decoding URLs containing passwords, API keys, or other sensitive information in shared or public environments. Always use HTTPS URLs for sensitive data transmission.
