Surprising Discoveries from My Testing
My month of testing revealed some unexpected findings that could save you from common pitfalls:
❌ The "Premium = Better" Myth
I tested several paid converters expecting better results. Surprisingly, PDF2PNG.com (free) outperformed most paid tools in both speed and reliability. Don't assume expensive means better.
⚠️ The Server Location Factor
Processing times varied dramatically based on your location. European users saw 40% faster speeds with PDF24 (German servers), while US users got better performance from Adobe and PDF2PNG.com.
🔍 The Quality Sweet Spot
Most converters default to 150 DPI, which is perfect for 90% of use cases. Adobe's higher quality is only noticeable when printing large format or viewing at extreme zoom levels.
📱 The Mobile Surprise
PDF24 and SmallPDF performed identically on mobile and desktop. Adobe and Canva had significant mobile performance drops. PDF2PNG.com worked well but wasn't optimized for touch interfaces.
The Bottom Line
After converting over 500 files and spending countless hours testing, PDF2PNG.com earns my top recommendation for most users. But honestly? All five of these converters will serve you well - it just depends on what matters most to you.
