Advanced Settings & Best Practices

Fit Strategy

Choose how content adapts to the new page size: Scale to fit (preserves content, may shrink text), Add margins (keeps sizes, adds whitespace), or Crop (trims overflow regions).

Mobile Readability

Prefer larger font sizes, increased line height and generous margins. Use single‑column layouts and avoid dense tables.

Print Alignment

Match target printer formats (A4/Letter). Keep headers/footers within safe margins and test a print preview to catch landscape pages.

Image Quality

After resizing, verify image clarity. Combine with compression to control size without artifacts.
