常见问题
- 编码后还有 & 号？

URL Encode/Decode (English)
encodeURIComponent-level escaping and unescaping.
Belongs to “Encoding & Crypto”: Common encodings, hashes and escaping — all computed locally.
- Percent-escapes Chinese, spaces and special chars in URLs so they can be used in links.
- encodeURIComponent escapes more reserved chars (e.g. & = ?), good for encoding parameter values.
- Processing is done locally; nothing is uploaded.
Free, no sign-up; everything runs locally in your browser and files are never uploaded.

How to use it
- Open the tool：Open the “URL Encode/Decode” page — no sign-up and nothing to install.
- Prepare the input：Prepare the content or file to process: paste text or drop a file onto the page (this tool belongs to “Encoding & Crypto”).
- Provide the input：Paste your content into the input box or drop a file onto the page; you can also click “Sample” to try example data first.
- Adjust options and run：Adjust the options if needed, then click the process / convert / generate button.
- Get the result：Everything runs locally in your browser; copy or download the result — your files are never uploaded.
FAQ
- Still have & after encoding?
- With encodeURI, & = / are kept — good for a whole URL; to encode a parameter value, use component mode.
- Where does + come from?
- Form submits often turn spaces into +; decoding auto-restores them to spaces.
