You don't need a poster printer or a trip to a print shop to hang a large image on your wall. Planar is a free browser tool that scales, crops, and tiles an image across a grid of regular sheets of paper — print each page on your home printer, trim, and assemble them into a full-size poster.

What It Actually Does

  • Poster tiling — splits a large image across a multi-page grid sized to A4 or US Letter paper, ready to print and tape together
  • Exact dimension calibration — set the real-world physical size you want the final printed image to be, and the tool works out the scaling and page count for you
  • Cropping and scaling — adjust exactly how the image is framed before it gets split across pages
  • Background removal — strip the background out of an image instantly, directly in the tool, before printing

Everything Runs Locally — Nothing Uploaded

Planar is built to be 100% private, local, and serverless. Your image is processed entirely in your own browser rather than being uploaded to a server for processing — worth knowing if you're working with personal photos or anything else you'd rather keep off a third-party server.

Why This Beats a Print Shop for Small Posters

Getting a large print made at a shop usually means paying per square foot and waiting on turnaround. For a lot of casual use cases — a poster for a dorm room, a large reference image for a workshop, event signage, or a big piece of wall art — printing it yourself across a handful of sheets and taping them together is faster and effectively free, using paper and ink you probably already have.

Who This Is Useful For

This is a strong fit for anyone printing a large reference image or diagram for a classroom or workshop, DIY poster and wall art projects, small business owners making quick in-store signage without a design budget, and anyone who needs an image at an exact physical size — like a template or pattern for a craft project — rather than just "big." If you need genuinely photo-quality large-format output with no visible seams, a professional print shop is still the better choice — but for fast, casual, and free poster printing, this covers the job well.
