Free Poster Tiling Tools: Split Images for Big Printing
Poster tiling means splitting one image across many printed pages so you can assemble a poster far larger than your printer’s paper size. The good news: you do not need to pay for this. Every tool on this page is free, and each one fits a different situation—offline desktop work, quick online splitting, phones, or artistic halftone prints.
The 5 Free Poster Tiling Tools, Head to Head

PosteRazor Desktop: Maximum Precision, Free Forever
PosteRazor is the precision instrument of free tiling tools. You set the exact poster dimensions (say, 100×70 cm), pick your paper size, and it produces a multi-page PDF with configurable overlap and alignment marks for assembly. Being open source (GPL) and offline, there are no uploads, no accounts, and no watermarks. The latest stable release v1.5.2 runs on Windows, macOS, and Linux. Trade-offs: you must install it, and the wizard-style interface looks dated—but it walks you through every step. Get PosteRazor here.
PosteRazor Online: No Install, Same Idea
Our online tool is the zero-install route: upload an image in your browser and get split pages back, with no software to download. It is ideal on Chromebooks, school computers, or phones where you cannot install programs. Trade-offs: it needs an internet connection, and a desktop install of PosteRazor gives finer control over dimensions and overlap. For everyday posters, though, the online tool is all most people need.
Blockposters: The Quickest Split
Blockposters strips tiling down to the essentials: upload, choose how many pages wide, print. There is nothing to learn, which makes it perfect for one-off jobs like a classroom chart or a party sign. Trade-offs: it offers less control over exact dimensions, margins, and overlap than PosteRazor, so precise projects (maps, scaled diagrams) belong in a desktop tool. Check the official site for its current options.
Posteriza: Text + Images on Windows
Posteriza is different from pure splitters: it is a free Windows program for composing posters with text banners and images, then printing them tiled. If your poster is an announcement with a headline rather than a single photo, Posteriza handles both layout and splitting. Trade-offs: Windows-only, and it has not seen major updates in a while. For pure image splitting on any platform, PosteRazor is the sharper tool.
Rasterbator: Halftone Art, Not Precision
Rasterbator converts images into large halftone dots and tiles them across as many pages as you like. The result looks like pop-art—fantastic for bedroom walls and exhibitions. Trade-offs: it cannot reproduce fine detail or readable text; that stylized look is the whole point. See our PosteRazor vs Rasterbator comparison for a deeper dive.
