About Str Length

Str Length is a free, browser-based utility designed to make text and data formatting as quick and frictionless as possible. Built to be the kind of tool you bookmark and use weekly: no surprises between visits, no degraded free tier, and a UI that gets out of the way. It pairs naturally with the other text utilities here when you need to chain a quick workflow.
