BookletMaker: PDF Imposer

BookletMaker turns any PDF into a print-ready booklet — saddle-stitched signatures, 2-up and 4-up imposition, cleanup tools, page numbers, watermarks, and an inline editor that lets you fix typos in baked-in text without going back to the source file.

KEY FEATURES

• Imposition: standard saddle-stitched booklets, mini-booklets (4 pages per side), 2-up, 4-up, or any custom n-up grid. Pick paper size, orientation, and direction; BookletMaker handles the page ordering and rotation.

• Signature folding: configurable signature size from a single booklet to 32-page signatures. Built-in creep compensation pulls inner pages out by a configurable amount per sheet so the trim cut stays straight.

• Cleanup: crop margins, remove blank pages, split landscape spreads into portrait halves, rasterize corrupted source PDFs, choose which page-boundary box (media / crop / trim) to use as imposition source.

• Page numbers: pick position (top, bottom, inner, outer), font size, color, format token ({n} or {n} of {total}), starting offset, and skip-first behavior for cover pages.

• Hole punch: leave the right margin for 2- or 3-hole binders with visual guides.

• Watermark + letterhead: text watermark with adjustable opacity. Use any 1-page PDF as a letterhead applied to all pages, first page, odd, or even.

• Color & ink: convert to grayscale or lighten content for draft prints.

• Inline editor (Mac): tap a paragraph to edit text directly in the PDF — BookletMaker preserves the original font, size, and color, and reflows surrounding content so longer edits push down or shorter edits pull up.

• Find & Replace: search across the document and replace every match with proper font matching.

• Highlight, redact, sticky notes, ink, signature stamps.

• OCR: run Apple Vision over scanned PDFs to make them searchable. Save the recognized text as a plain-text file.

• Output: save imposed PDF, flatten annotations, export with a password, export each page as PNG / JPEG / TIFF, copy as PDF, or print directly via AirPrint.

• Duplex printing — including non-duplex printers: prints fronts in one pass, then prompts you to flip the stack and reload the input tray so it can print the backs. Works on any AirPrint printer.

• Booklet Factory: batch-impose dozens of PDFs in one run, drop the output to a folder of your choice.

• Presets: save your settings as a named preset; presets sync across your devices via iCloud.

PRIVATE BY DESIGN

BookletMaker runs entirely on your device. Your PDFs never leave your Mac or your iPhone / iPad. No accounts, no cloud upload, no analytics on what you print.

NOTES

• macOS app supports inline text editing, find & replace, and the full Booklet Factory queue. iOS app supports the same imposition pipeline plus touch-driven highlight, redact, ink, and stamp annotations.

• AirPrint via the system print panel.

• Files-app integration on iOS: drop PDFs into BookletMaker's folder under "On My iPhone / iPad" and they appear in the queue.
