Free tools

Small, focused utilities that solve one problem well. Free tools are how most people first meet SOVEL — and they are held to the same standard as the products.

No account to do simple work.

A tool that calculates, converts, compresses, counts or performs a simple browser-local transformation should not demand an account. Requiring a login for that is friction, not value.

An account is only justified when it unlocks something real: saving history, cloud storage, synchronised projects, premium features, purchase and download management, or subscription access.

Our rule

Simple browser-local tasks run without an account. Anything that needs to remember your work will say so before asking you to sign in.

What free tools are for

  • Immediate use — open it, use it, done.
  • Honest limits — a tool that does one thing does not pretend to do more.
  • A real doorway — if a tool is not enough, the deeper product is clearly signposted.
