Best Settings to Convert Images to PDF (A4/Letter, Margins, Fit)
Turning a bunch of photos into a clean, single PDF is easy—if you pick the right settings. This guide shows the **best page size, margins, and fit modes** to make tidy PDFs for printing, email, and sharing—using our free Image → PDF tool.
Quick Start (Best Defaults)
- Page: A4 Portrait (or Letter in the U.S.)
- Margin: 10–15 mm
- Fit Mode: Contain (no cropping)
A4 vs Letter—Which Should You Use?
| Use Case | Choose | Why |
|---|---|---|
| Outside U.S./Canada | A4 | Standard for offices/schools, matches most printers |
| U.S./Canada | Letter | Default printer size; fewer scaling surprises |
Fit Modes Explained
- Contain (Recommended) – Fits the entire photo within margins. No cropping. Best for notes, receipts, IDs.
- Cover – Fills the page edge-to-edge. May crop edges. Good for gallery/photo books.
- Fit Width – Matches width inside margins; height varies. Useful for long vertical documents.
- Fit Height – Matches height inside margins; width varies. Good for wide landscapes.
Tip: If your files are very large, run them through the Image Compressor first to shrink the final PDF size.
Best Margins
Margins of **10–15 mm** keep content away from printer edges and make documents readable. Use **0–5 mm** only for edge-to-edge photo layouts.
iPhone & Android Capture Tips
- Use a scanning mode (Notes/Drive/Files apps) for crisp text.
- Shoot in bright, even light; avoid shadows.
- Keep orientation consistent (all portrait or all landscape) for a cleaner PDF.
