Split an image into A4 pages

How splitting to A4 works

A4 is 210 × 297 mm, taller than it is wide. The splitter measures your image's width and cuts each strip to the height that fills a full A4 page at that width, so a portrait page is used edge to edge with no awkward scaling.

Because the slices are sized to the page, the resulting PDF prints one strip per sheet with a small margin and nothing clipped. Set your printer to Actual size (not Fit to page) so the proportions stay true on paper.

A4 pages as a PDF or as images

A PDF is the cleanest output for printing: one file, predictable pages, the same on every device. This page defaults to One PDF for that reason. If you would rather drop the pages into another document, switch the output to separate images and you get one file per A4 page instead.

Need US Letter instead of A4? The splitter has a Letter option right beside A4 that sizes each strip to 8.5 × 11 inches. Everything else works the same way.

Before you split, get the width right

Each A4 page is only as sharp as the image is wide, since the strip is scaled up to page width. For crisp print, start from a high-resolution capture; if the image is narrow, resize it wider first so the printed text does not look soft.

The whole job runs locally. A scanned document or a private screenshot is turned into a print-ready PDF without the file ever leaving your device.
