Technical Architecture & Execution Mechanics
RFC 3986 Percent-Encoding Specification
Characters outside the unreserved set [A-Za-z0-9-_.~] are converted to UTF-8 byte sequences, with each byte represented by a percent sign followed by two hexadecimal digits.
Encoded_URL = encodeURIComponent(Raw_String)Technical Limitations & Operational Constraints
- Malformed percent-encoded strings with incomplete hex pairs (e.g. '%2') will flag a URIError.
Key Specifications & Capabilities

Frequently Asked Questions & Answers
What is the difference between encodeURI and encodeURIComponent?
encodeURI preserves URL structure delimiters (/?:@&=+$#), while encodeURIComponent encodes everything except alphanumeric characters and -_.!~*'().
Are my files uploaded, analyzed, or stored on NexVaani servers?
Where supported, tool inputs and files are processed locally inside your web browser using WebAssembly and HTML5 Canvas. Your files are not uploaded to NexVaani file-processing servers.
