Two pages side by side on one PDF page — for example a magazine exported as spreads from InDesign, with two A4 pages on a landscape A3 sheet. Many print shops and readers want single pages.

What happens to the front and back cover?

With "Spreads only", only landscape pages are split. Portrait pages such as the front and back cover pass through unchanged, so a typical magazine export comes out in the right order.

Does the quality suffer?

No. Each half is the same page with a new crop box. Nothing is rasterised, and text stays searchable and selectable.

What does spine bleed mean?

If an image runs across the spine, you can carry a few millimetres of the facing page across as bleed. The TrimBox still sits at the spine, so the page prints at the right size. Existing bleed on the outer edges is always kept.

What does Undo booklet do?

A saddle-stitched booklet is printed imposed: the first sheet holds pages 8 and 1, its back 2 and 7, and so on. Undo booklet splits the sheets and puts the pages back in reading order, so you can edit or re-impose them.

What happens to my file?

It is processed on servers in the Nordics and deleted automatically shortly after. You can download a certificate of deletion as proof.

My scan is off-centre — will the cut still hit the gutter?

With the automatic cut position we look for the gutter on scanned spreads: the shadow in the fold or the blank strip between the two text blocks. If there is no clear gutter, the page is cut in the middle. If it still lands off, set the cut manually in percent.

Can I cut a page into more than two?

Yes. Choose Grid and set rows and columns, e.g. 2 × 2 to undo a 4-up sheet or split an A2 poster into four A4 pages. With overlap each piece carries a little of its neighbour, so they can be glued together.

Can I turn A3 into A4 with Split spreads?

Yes. A landscape A3 sheet holding two A4 pages becomes two A4 pages. If the sheet has bleed and crop marks, the outer bleed is kept and each page gets its own TrimBox.
