Split PDF Pages in Half — Cut Each Page Down the Middle

It splits each page of your PDF down the middle, turning one wide or tall page into two separate pages. This is ideal for scanned book spreads, double-page layouts, or A3 documents you need as A4.

Yes. Enable the Skip Cover toggle and the first page will be kept whole while all other selected pages are split.

Yes. Enable the RTL toggle for Arabic, Hebrew, or manga documents. This reverses the left/right output order so the right half comes first.

Yes. Use the Apply dropdown to choose All, Odd only, Even only, or a custom page range. You can also exclude specific page numbers from splitting.

No. Drag the split line to any position from 5% to 95%. This is essential for imperfectly centered scans where the book gutter is off-center.

The tool recognizes A2–A5, B4–B5, US Letter, Legal, and Tabloid. It shows the original and resulting page sizes (e.g. A3 → 2×A4) so you know exactly what you'll get.

Yes. Toggle between vertical (left/right) and horizontal (top/bottom) split. Horizontal is useful for tall pages or documents with top/bottom layout.

Yes. This is one of the most popular uses. Upload the scanned book PDF, adjust the draggable split line to match the gutter position, and download individual pages.

The tool detects the paper size automatically. When you split an A3 page vertically, the resulting pages are A4 size. The detected sizes are shown as labels (e.g. 'A3 → 2×A4').
