ShobFree: 300+ free everyday tools in one fast, private platform.

A free-to-use web platform I designed, built and deployed: PDF, image and document tools plus calculators and Bangla utilities, in English and Bangla, with no sign-up and files deleted automatically.

// the idea

Everyday digital tasks, without the friction.

Merging a PDF, shrinking a photo to fit a form, converting a file, writing in Bangla or working out a loan: people need these small jobs done many times a year. They should not need an account, an install or a lecture.

  • One place for hundreds of small tools, grouped so you can find the right one fast.
  • Free and no sign-up for the core tools.
  • Privacy first: uploaded files are removed automatically after the job, and many tools run entirely in the browser.
  • Built for Bangladesh as well as the world: a full Bangla interface, Bangla typing, Bijoy to Unicode, date and tax tools.

// product decisions

What I focused on as the builder.

  • Speed and clarity: each tool page explains what it does, how to use it and what to expect, in plain language.
  • Privacy by design: automatic deletion, and browser-side processing wherever a tool does not need a server.
  • Bangla as a first-class language, not a translation afterthought.
  • Search-friendly structure: one useful page per task, clear titles and descriptions, internal links and a growing library of guides.
  • Extensible platform: a shared tool framework so new tools can be added quickly and consistently.
