Công cụ này là gì?
URLs only tolerate a limited ASCII subset in many positions. Encoding replaces unsafe characters with percent sequences so analytics tags, search queries, and multilingual slugs survive transit. Decoding reveals the original human-readable text when troubleshooting tracking links.
Cách sử dụng
Paste the fragment that needs transformation — not necessarily an entire URL unless you intend every reserved character encoded.
Những lợi ích
- Cross-check marketing UTMs before publishing.
- Avoid manual hex tables.
Câu hỏi thường gặp
Does it encode full URLs?
encodeURIComponent will encode : and / — use on components (query values) rather than whole absolute URLs unless that is intended.
