To get the best results when you convert your PDFs to Flipbooks, follow these requirements and formatting guidelines.
Basic Requirements
- All pages must be merged into one file (we recommend using an Optimized PDF)
- However, we do not recommend binding multiple PDF files into a PDF Package
- Single-page cropped layout (no double-page spreads), with any crop marks removed
- All pages in the same orientation: either all-portrait or all-landscape, not mixed
- Pages in the correct order (can't be re-ordered after upload)
- Secured PDFs can be used, but security settings will be removed during conversion
Sizes and Dimensions
- Maximum page number is 1200 pages per file (but may be lower based on your specific subscription type)
- Maximum file size is 500 MB
- Maximum single-page surface area is 430 square inches
- No minimum size requirement for page area, but we recommend PDFs be at least 5 inches on all sides (wide/tall) for acceptable quality on larger displays
Text and Fonts
- Text should be "real" text (not images of text) to ensure it looks sharp when zoomed and can be parsed by search engines
- Embed all fonts used in the PDF
- Avoid CID and Embedded Open Type (EOT) fonts
Layout
- Use RGB Color Space for most accurate color conversion
- No minimum resolution for images, but we recommend at least 200 DPI for acceptable quality
- All layers merged
- All transparencies flattened
- Avoid overprint elements
- Delete clipping paths where possible to avoid white "ghost lines" which may appear after conversion
- Links and bookmarks, including to Named Destinations, will be maintained during conversion
- Embedded scripts, media (audio/video) and buttons will be removed during conversion, but can be added back post-conversion with the Page Editor
- PDF Comments will be removed during conversion
