How-to Guide

Combine Images into a Grid for PDF Export

PDF documents don't handle multiple inline images gracefully. A pre-composed grid image eliminates all layout problems: one image, one placement, zero formatting headaches.

Try MergeFrame (Free)

Anyone who has built a PDF report knows the pain of multi-image placement. The fix: compose images into a single grid before inserting. One image = one placement = zero problems.

For reports: 4 quarterly charts in 2×2. For proposals: problem left, solution right in 1×2. For docs: code + terminal + result in Strip of 3.

For A4 PDFs, export at 2480px (300 DPI) for print, 1654px (200 DPI) for screen. Use PNG for text clarity. All processing is local: sensitive documents never leave your device.
