Precision Tiling in 5 Simple Steps
PosteRazor simplifies the complex process of splitting large images into printable segments while maintaining pixel-perfect accuracy.
Import Image
Load your source image. Support for common formats including JPEG, PNG, BMP, GIF, and TIFF. No file size limits for high-resolution photography.
Paper Setup
Define your printer’s paper format (A4, Letter, A3, Legal) and orientation. The software automatically calculates the printable area borders.
Overlap Margin
Set the overlapping size for easy gluing. This crucial feature ensures a seamless transition between pages for a professional finish.
Poster Size
Scale your poster by absolute dimensions (meters, inches) or by the number of pages. Preview exactly how many sheets will be used.
One Tool, Endless Possibilities
Whether you are a tabletop gamer, an artist, or a professional, PosteRazor provides the precision you need to transform digital files into physical reality.
Tabletop Battle Maps
Perfect for D&D (Dungeons & Dragons) and Pathfinder players. Print massive, detailed tactical maps at 1-inch grid scale using standard home printers.
DIY Wall Murals
Create stunning feature walls without expensive custom wallpaper. Split high-resolution photography or digital art into multi-sheet masterpieces.
Banners & Signage
Ideal for birthday parties, protests, or store announcements. Produce long horizontal banners or vertical signs up to several meters in size.
Classroom Resources
Teachers can transform educational infographics into classroom posters. A cost-effective way to build a visual learning environment on a budget.
Pro Tip: When using PosteRazor for large-scale murals, we recommend using a 10-15mm overlap for optimal glue surface and alignment precision.

Advanced Troubleshooting & Expert Tips
Don’t let technical hurdles stop your project. Here is how to solve the most common issues when using PosteRazor.
Why is my poster blurry?
Solution: The source image’s resolution is too low. Always check the Effective DPI in the fourth step of PosteRazor. If it’s below 72 DPI, consider using an AI Image Upscaler (like Real-ESRGAN) before importing into PosteRazor to maintain sharpness at giant scales.
Pages don’t align perfectly?
The Fix: Printer mechanical drift is real. In Step 3 (Overlapping), ensure you select “Top Right” or “Bottom Left” alignment consistently. Also, disabling “Fit to Page” in your PDF reader’s print settings is mandatory to keep the scale at exactly 100%.
Large PDF file issues?
Tip: If PosteRazor crashes during PDF export, it’s usually a memory limit for extremely large TIFF files. Convert your source image to JPEG (High Quality) before processing. This drastically reduces the final PDF size without visible quality loss for home printing.
PRO TIP Always do a “Proof Print” of just 2 overlapping pages first to test your glue/tape strategy before printing a massive 50-page mural.
