Tips for Better PDF Output
- Consistent image sizes: For the cleanest PDFs, use images of the same dimensions. Use the Resize tool to standardize sizes first.
- Compress before converting: Large images create large PDFs. Run images through the Compress tool first to reduce the final PDF size.
- Use the right resolution: 150 DPI is good for screen viewing, 300 DPI for printing. Higher resolution means larger files.
- Order matters: Use drag-to-reorder to arrange pages correctly before converting.
