Understanding Quality in PDF to JPG Conversion

The quality of converted JPG images depends on several interconnected factors. Understanding these will help you achieve the best possible results.

Factors Affecting Output Quality

1. Source PDF Quality

Your output quality is fundamentally limited by the source:

• Vector PDFs: Created from design software, can scale to any resolution
• High-resolution scanned PDFs: Good source material for conversion
• Low-resolution scanned PDFs: Will produce low-quality images
• Image-based PDFs: Quality limited to embedded image resolution
• Text-based PDFs: Generally convert with excellent sharpness

2. Resolution (DPI)

The most critical factor in output quality:

• 72-96 DPI: Screen viewing only, looks pixelated when zoomed
• 150 DPI: Acceptable for web use, casual viewing
• 300 DPI: High quality, suitable for printing and professional use
• 600+ DPI: Very high quality, large file sizes, for archival or specialized needs

3. JPG Compression Quality

JPG quality settings affect the final image:

• 85-95%: Recommended for most purposes, good quality with reasonable file size
• 96-100%: Maximum quality, minimal compression, larger files
• Below 85%: Visible quality loss, only for extreme file size constraints

4. Color Space

Color handling impacts appearance:

• RGB: Standard for screen viewing, web use, and most applications
• CMYK: For professional printing (though JPG typically uses RGB)
• Grayscale: For black and white documents, smaller file sizes

Resolution and DPI Explained

DPI (Dots Per Inch) is the most important setting when converting PDFs to JPG images. Understanding DPI helps you choose the right setting for your needs.

What is DPI?

DPI measures the number of dots (pixels) per inch in an image. Higher DPI means more detail and sharper images, but also larger file sizes.

Calculating Image Dimensions

The DPI setting directly affects the pixel dimensions of your output image:

Formula: Pixel Width = Page Width (inches) × DPI

Example for standard US Letter size (8.5" × 11"):

• 72 DPI: 612 × 792 pixels
• 150 DPI: 1,275 × 1,650 pixels
• 300 DPI: 2,550 × 3,300 pixels
• 600 DPI: 5,100 × 6,600 pixels
