PDF booklet maker and PDF tools
Booklets ready to fold, PDFs small enough for email, PDFs from pictures and new page sizes — on your own computer, with no uploads. Your PDF is never changed: each new PDF is a copy.
Booklet and binding Works offline
- Booklet: print on both sides, fold in half, staple — two pages on each side of a sheet, in the right order
- On US Letter (pages 5.5 × 8.5 in) or on A4 (pages A5)
- Book (Amazon KDP paperback): a wider inside margin that grows with the page count, and page 1 on the right
- Spiral or comb binding: room on the left of every page for the holes
- Several PDFs at once

Smaller for email
Under 20 MB for Gmail: the pictures are made lighter step by step until the PDF fits, and text and lines stay sharp. Or smaller and still good to print (200 dpi), or smallest for screens.
Pictures → PDF
Collect pictures — or a whole folder of them — into one PDF, in the order you choose.
Page size
A4 ↔ US Letter, KDP trim sizes, cards and posters.
