A drawing, a pattern or a poster
on ordinary sheets
If a file is bigger than the paper in your printer, Splitizer divides it across several sheets you can print and assemble into one. Set the finished size and the tool works out the sheet count, the overlap, the cut lines and the assembly map. It’s free. Actually free.
- Free, no account.
- All sizes and exports are free. No sign-up, e-mail or payment card required.
- Runs in your browser.
- The file is processed on your device. Nothing is uploaded and nothing needs to be installed.
- Accounts for printer margins.
- Each sheet is calculated from the printable area of your printer, so the seams line up after assembly.
- Overlap for gluing.
- Set the overlap between sheets. Cut along the line and use the overlap to align and glue the sheets.
- Vector stays vector.
- PDF files are split without rasterizing them, so text and vector graphics stay sharp.
- Assembly map.
- A separate guide shows the complete layout and the position of every sheet.
