PDF wins for final, shareable documents because they look the same on every device.
Converting Scanned Documents
When converting phone photos of documents:
- Use good lighting (no shadows)
- Keep the camera parallel to the document (no angle)
- Crop the photo to just the document edges before converting
- Use the highest resolution photo available
For best results with scanned documents, crop first using our [Image Crop tool](/tools/crop), then convert to PDF.
