Intermediate3 minLearn how different page size options affect your PDF output.
- 1
Original Size Mode
Each PDF page matches the exact dimensions of the input image. A 1920Γ1080 photo creates a 1920Γ1080 PDF page. Best for high-resolution images or when exact dimensions matter.
π‘ Tip: Use this for photos or graphics where you want to preserve the exact image size.

A4 Format
All pages are standard A4 size (595.28 Γ 841.89 points). Images are scaled to fit with margins, maintaining aspect ratio. Perfect for documents intended for printing.
- 3
Letter Format
All pages are US Letter size (612 Γ 792 points). Like A4, images are centered and scaled to fit. Ideal for documents in North American markets.

Mixed Image Sizes
You can combine images of different dimensions. When using A4/Letter, each image is individually scaled to fit the page while maintaining its aspect ratio.
Advanced PDF Creation Tips
Advanced4 minBest practices for creating professional PDF documents from images.
- 1
For Photo Albums
Use high-resolution images (at least 300 DPI equivalent). Choose A4 or Letter for consistent page sizes. Consider landscape vs portrait orientation of your photos.
π‘ Tip: If most photos are landscape, A4 works well. For mixed orientations, each photo will be centered appropriately.
- 2
For Scanned Documents
Ensure all scanned pages have consistent dimensions before converting. Use Original Size to preserve scan resolution, or A4/Letter to standardize output.
π‘ Tip: For multi-page scans, verify page order before generating PDF.
- 3
For Presentations
Use Original Size mode with high-resolution slides. This ensures crisp text and graphics when the PDF is viewed at full size on screens.
π‘ Tip: If presenting on standard screens, consider converting slides to 1920Γ1080 images first for consistent sizing.

Optimizing File Size
Large images create large PDFs. Consider compressing images first using our image compressor if file size is a concern. Each image is embedded at full resolution in Original Size mode.
