About ToolSerenity

Who we are

Tech Serenity Trading Company

Tech Serenity Trading Company (tstcoman.com) is a technology and software business. We build practical tools for people who just want to get something done — without accounts, uploads or friction.

ToolSerenity started as a handful of internal utilities. We opened it up as a public platform so anyone, anywhere could use the same quick, reliable tools for free. New tools are added regularly.

Our parent company, Tech Serenity IT, builds custom software and dashboards for businesses.

Our principles

What we stand for

Private by default

Our image, PDF and data tools process your files entirely in your browser. Nothing you type or upload is sent to our servers — your data never leaves your device.

Genuinely free

Every tool works fully with no signup, no watermark and no paywall on core functionality. We keep the lights on with unobtrusive advertising, not by locking features.

Fast & no install

Tools open instantly in any modern browser on desktop or mobile — nothing to download. Most keep working even without a connection.

For everyone, everywhere

Whether you are a developer, designer, writer, student or just getting something done, our tools are built to be simple, clear and useful to a global audience.

What we offer
