I Built a Fast & Lightweight PDF Tools Website Using Next.js

While working with PDFs daily, I noticed most online PDF tools had one or more of these problems:

• Too many ads
• Slow processing
• Login requirements
• Watermark restrictions
• Poor mobile experience

So I decided to build my own lightweight browser-based PDF tools platform focused on simplicity and speed.

Tech Stack

• Next.js
• React
• Tailwind CSS
• SEO-focused routing
• Optimized Core Web Vitals

Features

• Split PDF
• Merge PDF
• Compress PDF
• JPG to PDF
• PDF to JPG

Main Goals

• No watermark
• Fast UI
• Mobile-friendly
• Secure browser experience
• Minimal design

One thing I learned during development is how important long-tail SEO is for utility websites.

Instead of targeting only:

• “PDF tools”

I started targeting specific search intent like:

• “split pdf online free”
• “split large pdf into multiple files”
• “compress pdf without losing quality”

That completely changed indexing and traffic potential.

I’m still improving:

• SEO structure
• performance optimization
• page indexing
• accessibility
• user experience

Would love feedback from developers here:

• What PDF feature should I add next?
• Any suggestions for scaling utility websites?
• Any Next.js optimization tips?
