**The Problem That Started It All**
It was 2 AM in Lagos, Nigeria. I had a client deadline in 6 hours.
I needed to merge 3 PDFs and compress them. Simple, right?
WRONG.
Every "free" PDF converter I tried:
â iLovePDF: "Sign up for free trial" (then $48/year)
â SmallPDF: 2 conversions per day limit (I needed 10)
â Sejda: Uploaded my files to their servers (client data!)
â Adobe: $15/month for basic features
I was furious. Why is something so simple so complicated?
**The Midnight Decision**
At 2:30 AM, instead of sleeping, I opened VS Code.
"Screw it. I'll build my own."
I knew it was possible to process PDFs entirely in the browser using:
- pdf-lib for PDF manipulation
- Canvas API for image conversion
- Client-side compression algorithms
No servers needed. No uploads. True privacy.
**72 Hours of Coding**
I didn't sleep much that weekend.
Built the core features:
â Merge PDFs
â Split PDFs
â Compress PDFs
â PDF to JPG/PNG
â Image conversions
Tested it obsessively. Made sure it was FAST.
Deployed to Vercel. Free hosting. Perfect.
**Why I'm Sharing This**
I'm 22. From Nigeria. No venture capital. No team. Just me.
I built ConvertFlow because:
1. **Privacy matters** - Your files should never leave your device
2. **Free should mean FREE** - No hidden limits, no bait-and-switch
3. **Simple tools shouldn't require accounts** - Just use it and go
I've been hustling for 2 years trying to make something work.
This is my shot.
If this helps even 100 people, it's worth it.
