💡 What is URL Encoding?
URL encoding (also known as percent-encoding) is the process of converting special characters in a URL into a valid ASCII format so browsers and servers can interpret them correctly. It replaces unsafe characters with a “%” followed by two hexadecimal digits. This ensures safe data transmission through web forms, APIs, and search parameters.

🌍 Why URL Encoding Matters
Web developers and SEO professionals use URL encoding to avoid issues with special characters in query strings, REST API calls, and dynamic web links. For example, spaces become %20 and special symbols like & or ? are encoded to prevent data corruption in browsers and HTTP standards.
🔒 Is This Tool Secure?
Yes — all encoding and decoding happen locally in your browser using JavaScript. No data is sent to external servers. Your text, URLs, or query strings remain private and secure at all times.

❓ Frequently Asked Questions
Is URL encoding the same as encryption?
No. URL encoding does not hide or protect information — it simply converts characters for safe web transmission. It is not a form of security or encryption.
Why do spaces convert to %20 or +?
Both symbols represent spaces in URLs. %20 is the standard encoding, while “+” is commonly used in query strings for form data.
Can I use this tool for APIs or query strings?
Yes. Developers use this for REST API parameters, form submissions, and search queries that include special symbols or non-English text.
Is URL encoding important for SEO?
Yes. Properly encoded URLs prevent broken links and ensure search engines correctly index your content.
Do you store or track any URLs?
Absolutely not. All encoding and decoding happen client-side with zero data collection.
