SEO & Utilities

Links, slugs, QR codes, and passwords

12 tools in this category.

These utilities build a link, a slug, a QR code, or a password on the page. The UTM builder adds utm_source, utm_medium, and utm_campaign, plus optional term and content. A blank field is left off the link. Existing query parameters stay. The page does not record a visit and does not shorten the address. The slug tool turns a title into a URL piece. The QR Code Generator encodes text or a URL of up to 1,200 characters as a 320 pixel PNG.

QR Code Generator Pro adds Wi-Fi, email, phone, SMS, and contact layouts, and it can change colors. The basic generator does not. The scanner reads the first QR code from the camera or from a PNG or JPG, and it does not open a link until you press Open link. The password generator uses the browser’s cryptographic random values and shows the string on the page. It is not a password manager, and it does not store the password.
