Start with a free output
Choose Easy Poster and an image or sample. Use A4 or US Letter, no more than 2 rows and 2 columns, standard quality and standard PDF. Do not enable Pro-only options such as custom assembly instructions. Open the saved PDF to check that it contains the intended pages.
Paper, margins and overlap
The paper size is not the printable area. Margins, overlap and the source proportions affect the finished size: four A4 sheets do not necessarily make an exact A2 poster. Match the PDF paper to the printer paper and inspect the seams in the preview.
Print at 100%
Disable unintended fit-to-page scaling when actual dimensions matter. Print at Actual Size or 100%, where available in your print application. Print one test sheet first. Do not run an already tiled PDF through a second poster-tiling process.
Check and calibrate
Measure the 100mm verification line or calibration square with a ruler. Check both axes and the print settings before compensating. Applying a saved X/Y printer calibration profile requires Pro. Calibration does not guarantee that every printer has zero error.
Assemble the sheets
Place pages in label order before cutting. Identify the trim side and overlap band, align neighboring guides, and temporarily secure the sheets before final assembly. Test the joining method on a small print.
PDF input and output
PDF import requires Pro. If the source has multiple pages, choose the one page to tile. Standard PDF export is available under all free conditions; high-quality PDF, high quality, line-art quality and line-width correction require Pro. Open the output and inspect small text and seams.
Save and transfer projects
Save the project in the app. Export a .postersplit file to make a snapshot, then import it on another device. Import creates new projects and does not overwrite existing ones. Later edits do not update the exported file. Purchase rights are not transferred; Pro output restrictions still apply.
Troubleshooting
For unexpected size, check PDF paper, printer paper and scaling. For inaccessible sources, confirm file access, download cloud files locally and check free storage. For purchasing problems, use Restore Purchases and check the Apple Account used for the purchase. Contact support with app version, device, OS, steps and error text; sending your source file is not required.
Uses
Free within these conditions
Print a photo across A4 sheets
Start with an image in Easy Poster. A4 or US Letter, up to 2×2, standard quality and standard PDF let you try the workflow for free.
Requires Pro
Tile-print one large PDF page or drawing
Choose one page from a PDF and split that page across printer sheets. PDF import and Drawing PDF mode require Pro; this is not PDF merging or batch conversion.
Requires Pro
Print patterns at actual size
Use a known reference dimension to prepare a full-size pattern. Actual-size mode and PDF import require Pro. Measure a test print before printing everything.
Requires Pro
Make a life-size poster
Set reference points and a target height for a person or object. Life-size mode requires Pro; a photo does not reveal the real dimensions automatically.
Requires Pro
Print a banner across ordinary paper
Prepare a wide design and check sheet order and seams. Banner mode requires Pro even when the design uses only a few sheets.
