10 Tips for Maintaining Image Quality
Preserve your image quality during conversion with these expert tips:
- Start with high-resolution images - 300 DPI is recommended for print, 150 DPI for web/display
- Use original images, not compressed versions - Avoid quality loss from multiple compression cycles
- Choose appropriate page size - Match page size to your image dimensions for best results
- Use "Contain" fit mode - Preserves aspect ratio without cropping or stretching
- Avoid converting low-quality JPGs - Garbage in, garbage out - start with good source images
- Save in highest quality settings - When saving from editing software, use maximum quality
- Don't upscale images - Enlarging images causes blurriness and pixelation
- Use lossless formats for graphics - For logos and text, PNG is better than JPG
- Check color profiles - sRGB is standard for web, CMYK for professional printing
- Preview before finalizing - Always check a sample page before batch converting hundreds of images
