Tips for Best Results
Image Preparation
- Resolution: Use images at least 150 DPI for readable text, 300 DPI for print quality
- Format: JPG for photos, PNG for screenshots or graphics with text
- Orientation: Rotate images to correct orientation before converting
- File naming: Name files in order (01, 02, 03...) for easier organization
PDF Settings
- Page size: Use A4 for international documents, Letter for US
- Margins: Add small margins to prevent content from being cut off when printing
- Compression: Balance between file size and quality based on your needs
⚠️ Important Considerations
- Large images result in large PDFs—compress images first if file size matters
- Some methods may reduce image quality; use the original resolution when possible
- Password-protect sensitive PDFs after creation if needed
Common Use Cases
📋 Document Scanning
Converting photos of documents (receipts, contracts, forms) to PDF creates searchable, archivable records. For best results, use a document scanning app that automatically detects edges and adjusts perspective.
🎨 Portfolio Creation
Artists, designers, and photographers often combine work samples into PDF portfolios for job applications or client presentations. Use high-resolution images and consider adding a cover page.
📚 Photo Albums
Combine vacation photos or event pictures into a PDF album that's easy to share with family and friends. One PDF is much easier to email than 50 separate images.
📑 Business Documents
Combine multiple pages of scanned contracts, multi-page forms, or presentation slides into unified PDFs for professional document management.
Troubleshooting Common Issues
PDF is too large
Solution: Compress images before conversion, or use a PDF compression tool after creation. Reduce image dimensions if they're larger than needed.
Images appear blurry
Solution: Use original high-resolution images. Some tools compress images during conversion—choose quality settings carefully or use a tool that preserves quality.
Wrong page order
Solution: Rename files with numbers before conversion, or use a tool that allows drag-and-drop reordering.
Orientation is wrong
Solution: Rotate images before conversion using your device's photo editor, or use a PDF editor to rotate pages after creation.
