Who I am

About me

A quick introduction, in case we haven't met.

Who am I

I'm a school student who's curious about programming, and right now I'm learning full-stack web development. I'm a little obsessed with browser APIs and privacy-preserving tech — I built the first version of PDF Master over a month.

Where I'm from

I'm from Bihar, specifically from West Champaran.

How it started

It's a long story that started 4 to 5 years ago, when I went through several technological things and started taking an interest in this field. From that day on, I kept thinking about programming and coding, and it made me obsessed with the technological world.

The timeline

My journey

How a curious kid on Instagram ended up shipping a PDF tool used around the world.

Four or five years ago

Obsessed with how things worked

I was completely obsessed with gadgets and technology, always messing around with things and trying to figure out how they actually worked.

First lines of code

An Instagram account changed everything

One day, while scrolling through Instagram, I came across an account called Ezsnippet (@ezsnippet) that ran a basic coding class. I decided to take a chance and sign up. The moment I started writing my first lines of code, something just clicked — I fell in love with programming because it meant I could actually build the things I was imagining.

The first project

Turning imagination into reality

I thought about converting my imagination into reality, and that frustration inspired me to make the 1st version of PDF Master, which included just 4 tools. But I was afraid of hosting it on the internet.

The lesson

Publish it anyway

Then I watched a video in which an influencer said that you should publish whatever you've made, even if it's small, because it lets people find your mistakes — which helps you understand your faults. That line inspired me, and I openly hosted my website.

Today

From 4 tools to a growing toolkit

That same fear-turned-into-frustration is what led me to keep building PDF Master into something bigger — a free, privacy-first home for the PDF tools I once couldn't find anywhere else.

The product

About PDF Master

I was fed up with the tools available for working with PDFs and images. I searched high and low for a solution, but when I couldn't find one, I decided to take matters into my own hands and create something myself.

This problem ultimately led to the creation of PDF Master — a tool designed to be simple, free, and safe for everyone to use. I wanted to make sure people could edit and manage their PDFs without jumping through hoops or putting their personal information at risk, all from the comfort of their own computer.

Mission & vision

I've got big plans for PDF Master, and what you're seeing now is just the beginning. My main focus right now is to build a set of 21 must-have tools, but that's not all — I want to keep adding top-notch features that deliver amazing results, all while keeping everything running smoothly on your own device.

I'm on a mission to make life easier for students, professionals, and anyone else who's fed up with paywalls, accounts, and cloud privacy issues. Looking ahead, I want to take this idea further and build a whole network of trustworthy websites.

We live in a world where companies are constantly tracking our every move and selling our data, but I don't want any part of that. Your privacy is important to me, so I keep tracking to a bare minimum — just basic page views to see what's working and how I can improve the tools. I promise to never track your personal information.

No sneaky data collection Your data is yours alone, and I'm committed to keeping it that way.
Built for everyone Students, professionals, and anyone tired of paywalls and forced accounts.
Powerful, not complicated A platform that's easy to use and respectful of your privacy and security.

Frequently asked questions

Not yet — I'm a school student, mostly self-taught, and still learning full-stack web development. PDF Master is where I put what I learn into practice.

Yes, it's just me — the code, the design, and every tool. That's also why new features take time, but each one is built with care.

An Instagram account called Ezsnippet, of all things. I signed up for a basic coding class on a whim, and later on i learned from @apna-college.

Yes — I'm happy2539 on GitHub and @happygupta_39 on Instagram, and you can always email me directly (see Contact below).

Yes, completely. There are no hidden fees, subscriptions, or premium tiers — every tool is free to use.

No. You can use every tool on PDF Master without signing up or logging in.

No. Every tool runs entirely in your browser using client-side JavaScript, so your files never leave your device.

Yes. PDF Master is built as an open-source project — you can find my code on GitHub at github.com/happy2539.

Almost none — just basic, anonymous page views to see what's useful. Nothing tied to you personally, and nothing about the files you process, since those never leave your browser.

Definitely. PDF Master currently has 12 free tools, and the goal is 21 — with more added as I keep learning and building.

// what I believe

I believe software should empower people —
not breach their privacy, ask for money,
or harvest their personal data.
