PDF Scaler

Large drawings are unreadable on A4. A P&ID, a schematic or a site plan meant for A1 or A0 shrinks to tags you cannot read — and a plotter is never where you need one. PDF Scaler prints it at real size on the paper every office has. HOW IT WORKS 1. Open a PDF from Files, iCloud Drive or any app. 2. Choose the final size: A0, A1, A2 or A3, portrait, landscape or automatic. 3. Print. Trim each sheet on its cut line and tape them together. You get the drawing at true A0–A3 size, built from A4 sheets. MADE TO BE ASSEMBLED • A sheet map comes first: the whole drawing with every page numbered. • Each sheet carries dashed cut lines and alignment crosses on its corners. • Every sheet names itself and its neighbours (Left: 2.2, Below: 3.3), so nothing gets mixed up. • A 6 mm overlap strip along two edges — butt the sheets, or glue them over it. • A thin line marks the edge of the final A-sheet, so the poster trims to exact size. • Portrait or landscape A4 pages, whichever takes less paper. PRINTS TRUE TO SCALE • Every sheet has a 100 mm check rule. Measure one before printing the rest and you know the printer did not shrink anything. • The drawing stays vector: lines and lettering are as sharp at A0 as in the original file. • Rotated pages, odd page sizes and multi-page PDFs are handled; pick the page you need. SIMPLE AND PRIVATE • Print straight away, or preview the sheets and share the PDF. • Free to use, with unlimited exports and no subscription. • No account, no ads, no tracking. Your files never leave the device. Ideal for process and piping engineers, maintenance crews, commissioning teams, architects, students — anyone who needs a big drawing on the wall or the workbench today.
