Three tools that finish a task

Each one solves a concrete task, works in your browser and asks for no account. Their limits are written on each page.

Pick one

The tools

  • QR code generator: static QR downloadable as SVG or PNG, with a contrast warning.
  • UTM builder: add UTM without duplicating or losing parameters.
  • Link checker: analysis of the address text, without opening it.

Why we don't open the link

The checker only reads the text

A checker that opens addresses from our servers could be used to probe internal networks (SSRF) or to attack third parties. That is why the current version is static. Destination and redirect checks will arrive only with a reviewed security design.
