About Card Cap
Card Cap was built for the moment you just need to handle this task and move on — no signup, no upload to a third-party server. The goal was to keep the path from "open the page" to "get the result" as short as possible. No mandatory account, no cookie wall, no upsell at every step. It is one of about a hundred utility tools that share the same philosophy: do one thing, do it well, get out of your way.
