About Online Tools Hub

A high-performance, 100% private in-browser utility suite developed by Telugu Public to empower students, job applicants, and digital creators.

Our Mission & Purpose

Every day, thousands of candidates applying for competitive examinations (such as APPSC, TSPSC, SSC, Railway RRB, Police, DSC, and Sachivalayam) struggle with strict portal upload requirements — exact photo dimensions, signature file sizes under 20KB–50KB, date stamps, and document formatting.

Most online converter tools require uploading private certificates and photos to unknown third-party servers, adding watermarks, or charging subscription fees.

The Telugu Public Solution: We built Online Tools Hub as a free, 100% client-side platform where files are processed entirely on the user's device. No uploads, no logins, no watermarks, and zero data storage.

What We Offer (53+ Browser Utilities)

  • Government Exam Presets: 1-click photo resizers, signature compressors, and name/date stamp creators matching exact official notification specifications.
  • PDF & Document Suite: Merge, split, compress, rotate, lock, unlock, and extract pages with military-grade 128-bit encryption directly in-browser.
  • Image & Media Studio: Background removal, smart photo compression, format converters (JPG, PNG, WebP), audio cutters, and voice recording.
  • Financial & Scientific Calculators: Scientific calculation with trigonometric & memory functions, Loan EMI schedules, SIP wealth projections, and GST calculation.
