About 1st Law

Most online tools for this task bury what you need behind ads and forms. 1st Law takes the opposite approach: load the page, do the job, leave. Everything happens client-side, which means your files and data never leave your machine. The interface is intentionally minimal so you can focus on the task instead of learning the tool. Like everything else in the utility collection, it is free, ad-light, and works on mobile as well as desktop.

When you'd reach for 1st Law

  • You're on a public or shared machine and don't want to leave traces of what you're working on.

    Travelers, contractors, anyone working from a friend's computer.

    Nothing is uploaded, nothing persists if you're not signed in.

  • You need to handle a one-off task right before a meeting and don't have time to install anything.

    Anyone working remotely on a borrowed or restricted machine.

    Open the page, get the result, paste it into your doc — under a minute.

  • You're hitting the daily limit of a paid SaaS and need a backup option for a single quick job.

    Marketers and ops people whose primary tool is metered.

    Stay productive without burning credits.

  • You're cleaning up a folder of files that accumulated over a project and need to standardize them.

    Drop each file in, copy the output, move on.
