When should I use A3 to A4 Split?

When you have an A3 landscape exam paper or document to print, but only have an A4 printer available. Common scenarios: teachers printing test papers, staff printing scanned exams, or students preparing study materials.

How is this different from shrinking A3 to fit A4?

Shrinking reduces the entire A3 to fit a single A4 sheet, making text tiny and hard to read. Splitting cuts the A3 in half and places each side on its own A4 page, keeping text at the original size for a comfortable reading experience.

What if the scanned fold line is off-center?

That's exactly the problem this tool solves. After uploading, drag the blue crop line left or right to align with the gap between pages. Each page of a multi-page PDF can be adjusted independently.

Will the printed A4 pages look blurry?

No. The tool renders at high resolution—even on an old black-and-white laser printer, math formulas and subscripts will come out sharp and clear.

Could exam content leak online?

No. All processing happens entirely within your browser—files are never uploaded. You can safely handle confidential test papers, and the tool works even when offline.

How many pages can I process at once?

You can upload multi-page PDFs or multiple images for batch processing. Each page has its own adjustable crop line, and exports are generated per source file—multiple files are automatically packaged into a ZIP for easy download.
