FolioFold: PDF Booklet Maker

Turn an existing PDF into something you can fold, bind or hand out. FolioFold arranges reading pages into print-ready sheets on your Android phone or tablet, with clear previews before you export.

One-time purchase. No ads, no subscription, no account. Works fully offline.

FOUR PRINT LAYOUTS
- Booklets: arrange nested sheets for folding, with end blanks added to complete the booklet.
- Signatures: split larger documents into groups of 4 to 64 pages, then gather the folded groups in order.
- Eight-page zines: arrange eight panels on one side, with optional fold and center-cut guides.
- N-up handouts: place consecutive pages across rows or down columns, with one to four rows and columns.

CONTROL THE SHEET
Choose A3, A4, A5, Letter, Legal or Tabloid, or enter a custom paper size. Swap orientation, set margins and gaps, rotate reading pages and insert blanks. Every preview identifies the sheet, side and source-page positions. Save a successful layout as a named preset for another project.

CALIBRATE MANUAL DUPLEX
Prepare the included A/B calibration sheets to learn your printer's feeding direction. Choose 0 or 180-degree back rotation, and forward or reversed stack order for a back-only PDF. Export all sides, fronts only or backs only. Printer feed paths, margins and scaling vary, so test a small sample first.

SAVE, SHARE OR PRINT
Prepare a clearly identified 300-dpi flattened PDF, save it through Android's document picker, share it or open the system print interface. Printed pages are rendered images: selectable text, links, editable forms and unlimited vector resolution are not retained in the output. Your imported original is preserved and can be exported unchanged.

YOUR PROJECTS STAY LOCAL
Keep private working copies of imported PDFs, project layouts, reading order and presets. Complete archives include originals and settings, with integrity checks before restore. Invalid archives leave existing projects intact. Archives are not encrypted. Automatic Android cloud backup is disabled, so export an archive before uninstalling or changing devices.
