Built for creators who care about craft.
I built GridCutter because I needed a simpler way to cut Instagram grids without uploading images, signing up for an account, or dealing with watermarks. It started from a personal need and grew into a tool I thought other creators might find useful too.
Why I built this.
I built GridCutter because I wanted a tool for people who like the idea of an Instagram grid but do not want to calculate the cuts manually. A lot of people just want a simple result that looks right on their profile without needing Photoshop or advanced editing skills.
The bigger problem was accuracy. Some web tools use the wrong cutting logic, so the finished posts do not align properly on an Instagram grid. Others try to force alignment by adding solid-color buffer areas, which can look awkward when someone opens the individual posts. I wanted to avoid both of those problems.
GridCutter is my attempt to make that process simpler: accurate 3:4 and 4:5 output, no watermark, no unnecessary steps, and no image upload to a server. It is an independent solo creator project from Indonesia, built from personal need and shared because I could not find another tool that handled this the way I wanted.
One image. Nine slices. Each output is sized for the same kind of profile-grid presentation GridCutter is built to support.
The principles behind the tool.
Privacy first, always
No upload means fewer trust concerns. GridCutter is designed to keep image processing in the browser so creators can work with more confidence.
The right ratio, by default
GridCutter is designed around the way creators expect their grids to appear on profile pages, so outputs feel more intentional and consistent.
No features for their own sake
The goal is focus, not feature bloat. GridCutter prioritizes the small set of controls that make grid cutting faster and easier to understand.
Free is not a marketing trick
GridCutter is intended to stay accessible. The core idea is a simple tool that people can use without turning a basic workflow into a subscription decision.
Quality output, not just fast output
We use canvas-based slicing to preserve full image fidelity. Your DSLR photos should stay sharp across all nine tiles.
Works everywhere
Desktop, tablet, phone — GridCutter runs in any modern browser without installation, plugins, or app store downloads.
Your images never leave your device.
GridCutter is designed to process images directly in the browser so creators can work without uploading photos to a remote image-processing service. The goal is a simpler, more private workflow with fewer moving parts.
