Questions before you spend paper

A folded sheet creates four pages. Pliego completes the next multiple of four and labels inserted blanks; it never confuses them with a blank page already present in your PDF.

On a sheet, pages that look rotated or out of order become correct after both sides are printed and folded. If the physical back is upside down, test the 180° back rotation.

It means printing both sides of a sheet. Automatic mode creates one interleaved PDF; manual mode creates separate front and back files.

A landscape sheet folded down the middle usually needs short-edge flip. Drivers label and apply this differently, so always confirm with one marked sheet.

Yes. The result has eight positions: your six originals and two blanks appended at the end. You can see where they land before downloading.

Not while it is read, imposed, previewed, or downloaded: those operations stay in local memory. Hosting still receives normal requests that serve the app; a Vercel preview may include its toolbar.

The outer sheet needs the last page beside the first. Its other side pairs page two with the penultimate page; folding restores reading order.

A4 makes an approximately A5 booklet; Letter makes half-Letter. Content is fitted proportionally with margins, so exact 1:1 scale is not promised.

It prevents wasting the job when a tray feeds the other face, reverses sheet order, or the driver rotates backs. Mark top and front in pencil and test page one of each file.

No. Save a password-free copy. The selector validates locally and explains whether a file is encrypted, damaged, empty, over 80 pages, or larger than 10 MiB.

Any printer that accepts the chosen size may work, but Pliego cannot detect tray direction, physical margins, or driver rotation. Automatic needs duplex; manual uses one-sided printing and reinsertion.

Each page is normalized from its CropBox and rotation, then fitted proportionally. Inspect the preview: forms, signatures, links, and actions are not transferred.
