Frequently Asked Questions
Everything you need to know about processing files securely in your browser
Why is URL encoding (percent-encoding) necessary?
URLs can only contain a specific set of ASCII characters. Special characters (like spaces, ampersands, question marks, and non-ASCII symbols) have structural meanings or are invalid in URLs. URL encoding converts these characters into a % followed by their hexadecimal value.
What is the difference between URL encoding a full URL vs. a query parameter?
Encoding a full URL keeps structural characters (like http:// and /) intact, whereas encoding a query parameter converts all special characters (including /, :, and ?) to ensure they do not break the query string structure.
Is it secure to decode sensitive URLs here?
Yes, this encoder/decoder operates entirely inside your web browser. No parameters, tokens, or URL paths are sent to external servers, protecting your security tokens and query strings.
Does this tool support decoding of UTF-8 characters?
Yes, the tool handles standard UTF-8 characters, multi-byte emojis, and international characters correctly during both encoding and decoding processes.
