Free use and requirements

Use this tool for free without a KitNelo account. Processing runs in your browser; input limits, browser support and device memory still apply.

This uses encodeURIComponent rather than encoding a complete URL while preserving all delimiters.

Encode a URL Query Component for Free

Paste the text value for a query parameter and apply URI component encoding before inserting it into the URL. Encode individual values rather than the entire address, because encodeURIComponent also escapes characters that separate URL components.

Decode Percent-Encoded URL Text for Free

Paste a percent-encoded component and decode it to inspect the original text value. Review reserved characters and the intended encoding layer before reusing the result, particularly when a value has already been encoded more than once.

Use a URL Encoder and Decoder for Free

Switch between component encoding and decoding to prepare or inspect a URL field. Check the output in its actual position within the address, since this tool follows encodeURIComponent rules and does not preserve all delimiters of a complete URL.
