About Free Image Splitter

Free Image Splitter is a free, browser-based tool that turns any image or PDF into printable pages you can assemble into posters, banners, and wall-sized prints — on the printer you already own.

Why this site exists

Printing something bigger than a sheet of Letter or A4 paper shouldn't require a large-format printer, a trip to a print shop, or expensive software. The technique — splitting an image into tiles, printing each tile at 100%, and taping them together — has been around forever. What was missing was a tool that did it properly: exact grid math, aspect ratio preserved, seams that actually line up, overlap guides for gluing, and honest feedback about print quality before you waste paper and ink.

Most online splitters upload your file to a server, cap the resolution, stamp a watermark, or hide the useful options behind a paywall. This one does none of that. Everything runs in your browser: the file never leaves your device, the output is full resolution, and every feature is free with no signup.

Who makes it

I'm Sebastian Sajoux, a builder and entrepreneur, and Free Image Splitter is a product of Venture Success, my company in the United States. I build and maintain the tool, write the printing guides, and answer the email. The guides come from the same place the tool did — actually splitting, printing, trimming, and taping images at home, and writing down what works: which DPI is enough at viewing distance, why "Fit to page" ruins alignment, when an overlap beats a butt joint.

How the tool works

The splitter is plain JavaScript running locally in your browser. When you drop in a file, it's read directly into memory on your device, sliced into a true N×M grid with your chosen paper size, margins, and overlap, and exported as a multi-page PDF or a ZIP of PNGs — all client-side. There is no upload step and no server that ever sees your image. That's also why it's fast: a 100-megapixel poster splits in seconds because nothing travels over the network.

The same applies to the image upscaler: high-quality stepwise resampling with an optional sharpening pass, computed on your machine, downloaded straight from your browser.

How the site is funded

The tool is free and always will be. The site shows ads (via Google AdSense) to cover its costs — that's the entire business model. No premium tier, no locked features, no selling data. You can read exactly what the site does and doesn't collect in the privacy policy.
