What Octavo does on Mac
Octavo is a native macOS app for PDF imposition and booklet printing that rearranges pages into the correct sheet order for folding, stapling, hole punching, or binding.
Developed by Double and Thrice Ltd., Octavo targets anyone who has wasted paper figuring out duplex booklet page order. You import a PDF or images, clean up crooked scans with rotate, crop, straighten, and perspective tools, then apply an imposition style such as saddle-stitch, multi-signature, comb binding, tri-fold, business cards, 8-page mini zine, or concertina zine. Live preview shows reader spreads and imposed sheets before you print or export.
Typical Mac workflow
Export your layout from Word, InDesign, or another tool as a PDF, drop it into Octavo, choose saddle-stitch booklet, set inside and outside margins, add fold and crop marks, and print duplex to your home or office printer. Octavo handles blank-page padding, media assignments per sheet, and manual duplex workflows when auto-duplex is unavailable. Mini zines can be printed without purchasing the full unlock.
Version 1.1
Build 1.1 adds Octavo Templates so you can save frequently used imposition settings and pick them from a template gallery when creating a new document. Fixes address page number placement on 1-up duplex layouts, spine-edge right layouts, spine handling in 1-up and comb-binding reader spreads, and page-strip scrolling while dragging pages.
