Combine images, PDF, Scans, everything into one clean document — then write all over it. Handwrite notes on real A4 pages with Apple Pencil, place images anywhere, and mark up any page. No account, no cloud — everything stays on your iPhone or iPad. A4Pad is the fast, private way to bring the files you already have into one tidy document. Combine existing PDFs, photos, and screenshots — plus fresh camera scans when you need them — into a single organized notebook. Or open one existing PDF just to annotate and highlight it directly, no merging required. No sign-up, no learning curve, no clutter. Arrange the pages exactly how you want, mark them up, and export a single polished PDF — all on device. **A notebook that starts from your documents.** Most note apps give you a blank page.

Handwrite with Apple Pencil on iPad, or with your finger on iPhone. Strokes stay on their own layer, so you can erase and adjust them later without ever touching the page underneath. **COMBINE & ORGANIZE** • Combine existing PDFs, photos, and screenshots into one document • Reorder, duplicate, and organize pages with a tap • Convert images to PDF automatically on export • Create portrait or landscape documents — your choice per notebook **PLACE IMAGES ON A PAGE** • Drop photos, logos, or screenshots onto any page • Move, resize, rotate, duplicate, and reorder them like objects on a slide • Rotation snaps to straight angles, so things line up without fiddling • Paste straight from the clipboard • Your notes stay on their own layer, always above the images **HANDWRITTEN NOTES & ANNOTATION** • Take handwritten notes on blank A4 pages — plain, ruled, squared, or dotted • Or write directly onto your scans, PDFs, photos, and screenshots • Full Apple Pencil support on iPad — pen, pencil, marker, highlighter, and eraser • Finger-friendly on iPhone, with the same tools • Notes stay on their own layer — erase or adjust strokes later, the page underneath is never altered • True A4 format on every page, so notes stay clean and print-ready **IMPORT FROM ANYWHERE** • Drop in existing PDFs — pages are merged in automatically • Import photos and screenshots from your Photo Library or the Files app • Send into A4Pad from any app with the system Share Sheet • Scan paper documents with your camera when you need to **EXPORT** • One tap to export a single, print-ready PDF at a clean 150 DPI • Share via Mail, Messages, AirDrop, or any app **PRIVATE BY DESIGN** • Everything stays on your device — no account, no cloud, no login • No trackers, no ads, no data collection • You're always in control of your files **NO LIMITS, NO FRICTION** • Unlimited Collections, Notebooks, and Pages • Every feature is available the moment you open the app • Organize into Collections and Notebooks for a clear structure across every project Fast, private, and focused — on iPhone and iPad.
