Web Tools
URL encoding, HTML editing and cleanup, colour conversion. Most of these exist because browsers and servers quietly disagree about what a character means in a given position — `/` in a path versus in a query string being the classic example.
The colour converter shows hex, RGB, HSL and CMYK together, which is the fastest way to notice that a "brand colour" is outside the printable gamut.
- Color ConverterConvert between HEX, RGB, HSL, HWB, LAB, LCH, CMYK and XYZ in real time, with batch input and WCAG contrast checks
- HTML Online EditorWrite HTML on the left and watch it render live on the right. Edit the rendered page directly, click any element to restyle it (color, size, padding, margin), upload an .html file, preview at desktop / tablet / phone sizes and zoom in on details, then copy the source, download the file or open it in a new tab.
- HTML strip / cleanRemove style/id/class attributes from HTML, or strip all tags to plain text.
- Temporary ClipboardTurn text, images or attachments into a short link you can open on another device or send to someone. Choose an expiry, scan a QR code, pick your own code, burn after the first read, or lock the text with a password.
- URL Encode and DecodePercent-encode or decode URLs, with three separate scopes: parameter value, whole URL, or double encoding. Also splits a query string into key-value pairs.

Common questions
Why does my encoded URL become %25 something?
Double encoding. The `%` of an existing escape was itself escaped. Encode exactly once, at the point of interpolation.
