Foldly: Booklet PDF

About this app

Want to print a PDF as a folded booklet — a zine, a program, a short manual or a story for the kids? Foldly reorders and pairs the pages in saddle-stitch order, so you just print double-sided, fold down the middle and staple. Pick a PDF, check the sheet-by-sheet preview, and tap Make Booklet. Share the result or save it to Files, then print it from any app. • SADDLE-STITCH PAGE ORDER — two pages per landscape sheet side, arranged so that after printing, stacking and one center fold the pages read 1, 2, 3 … in order. • BLANKS HANDLED FOR YOU — booklets need a multiple of 4 pages; Foldly adds the blank pages at the end and tells you how many, and how many sheets of paper you need. • SHEET-BY-SHEET PREVIEW — see which pages land on the front and back of every sheet before you print. • STAYS SHARP — pages are placed as vectors, not screenshots, so text prints crisp. Each page is kept upright, scaled to fit its half and trimmed to its visible page area. Links and bookmarks are carried over where possible. • BATCH MODE — with the unlock, turn up to 50 PDFs into booklets in one go. • SAME PAPER AS YOUR PDF — the booklet uses your document's page size turned sideways, so a Letter or A4 PDF prints on Letter or A4 paper, each page shrunk to half size. How to print: choose double-sided printing and flip on the short edge. If your printer can't print double-sided, Foldly can't do that part for you. Limits: PDFs up to 200 pages and 80 MB. Everything happens on your iPhone — your PDF is never uploaded and no account is needed. Your first booklet is free. A one-time $4.99 purchase unlocks unlimited booklets and batch mode. No subscription, no ads. Questions: overlapmarr@gmail.com
