About Convertor-Hub
Built by a student who got tired of slow, ad-filled tools
The Real Story
Hi, I'm Deepak Kushwaha — a student and self-taught developer from India.
I built Convertor-Hub because I was frustrated. Every time I needed to compress an image or calculate EMI, I'd end up on websites that either:
- • Took forever to load (too many ads)
- • Wanted me to create an account for a 5-second task
- • Uploaded my files to unknown servers (privacy concern)
- • Had confusing interfaces with hidden premium features
So I decided to build something different. Every tool on this site runs entirely in your browser. When you compress an image or calculate your loan EMI, the processing happens on your device. Nothing gets uploaded to any server. I don't see your files. I don't track what you convert.
This isn't a company with investors demanding growth metrics. It's just me, maintaining a set of tools that I personally use and want to share with others who face the same frustrations I did.
Why You Can Trust These Tools
Your Data Stays on Your Device
Image tools use HTML5 Canvas API. Text tools use JavaScript string methods. Calculators use standard math formulas. Everything runs locally in your browser — check the network tab in DevTools if you want to verify. You won't see any file uploads.
No Account Required
I don't collect emails. I don't build user profiles. There's no database storing your information. You use the tool, you leave. That's it.
Transparent About Limitations
Each tool page explains what it can and can't do. The background remover works great on solid colors but struggles with complex scenes — I say that upfront. The EMI calculator uses standard banking formulas but isn't financial advice. I'd rather you know the limitations than be disappointed.
Open to Questions
If you want to know how a specific tool works, email me. I'll explain. If you find a bug, tell me. I'll fix it. This site is a genuine effort to be helpful, not a cash grab.
How The Tools Work
Image Tools
Built using HTML5 Canvas API and JavaScript. Images are loaded into memory, processed using canvas drawing methods, and exported as new files. The original file never leaves your browser.
Financial Calculators
EMI uses the standard amortization formula: EMI = P × R × (1+R)^N / ((1+R)^N - 1). SIP uses compound interest with monthly contributions. GST calculations follow Indian government rates. These are the same formulas banks use.
Text Tools
Word counting uses JavaScript split() and regex. Case conversion uses built-in string methods. Text-to-speech uses the Web Speech API built into your browser — no external services involved.
QR Codes
Generated using a client-side QR library with high error correction. The QR code is rendered as a canvas element and exported as PNG. Your data doesn't go through any server.
Important Note
The financial calculators (EMI, SIP, GST) are for informational purposes only. They use standard formulas but shouldn't replace professional financial advice. Always verify important calculations with your bank or financial advisor. Tax laws and rates can change — the GST calculator uses current rates as of the last update but may not reflect recent changes.
