We've all been there: you convert a crisp PDF document into an image, and the result is pixelated and unreadable. This usually happens because of low DPI (Dots Per Inch) settings.
1. The "150 DPI" Sweet Spot
Most standard web converters default to 72 DPI, which is fine for thumbnails but terrible for reading text. JustPDF2JPG uses a dynamic scaling engine that renders images at roughly 150-200 DPI. This ensures that even small text remains sharp when converted.
2. Vector vs. Raster
PDFs are "Vector" files (math-based shapes), while JPGs are "Raster" files (pixel-based). To maintain quality during this transition, you need a converter that renders the vector data at a high scale before saving it as an image. Our tool scales the viewport by 2.0x before capturing the image.
3. Why Browser-Based is Better for Quality
When you use a server-side converter, they often compress the image heavily to save bandwidth costs. Since JustPDF2JPG runs on your own device, we don't need to compress your files. You get the raw, high-quality output every time.
