FAQ

encodeURI vs encodeURIComponent?
encodeURIComponent encodes all reserved chars (/:?@) for single param values; encodeURI keeps URL structure for whole links.
Batch processing supported?
Yes, line-by-line batch encode/decode handles CJK, spaces, & and = — faster API param debugging.
Can multiply-encoded strings be decoded?
Encoded vs raw input is auto-detected with hints; multiply-encoded strings decode layer by layer.
