Add a Grid to a Photo Online — Free, No Signup, No App
To add grid lines to a photo for drawing, just upload any image above — JPG, PNG, WEBP or GIF — and choose your rows and columns. The grid overlays instantly, and you can add grid lines in any color, thickness or opacity before you download. Works on iPhone, Android and desktop, right in the browser: nothing is installed, nothing is uploaded to a server, and there is no signup or watermark. If you want a square grid on a photo for the classic grid drawing method, start with 8×8 or 12×12 — or let our grid calculator work out the exact divisions for your canvas. Prefer paper? Pair it with printable grid paper and you have the complete setup, free. And if you would rather have the grid as a separate transparent layer for Procreate or Photoshop, the grid overlay tool does exactly that.
How many squares should you use? Fewer than you think. An 8×8 grid is enough for most head-and-shoulders references — every square is big enough to judge a shape at a glance, and the drawing stays fun instead of feeling like paperwork. Move to 12×12 when facial features need to land more precisely, and save 16×16 and finer for large canvases and murals where the extra checkpoints earn their keep. Two rules do most of the work: the number of rows and columns must match between your reference and your paper, and if you keep losing your place, your grid is too fine — step down one level. The grid size guide walks through every trade-off.

Frequently Asked Questions
▸What is a grid maker?
A grid maker overlays a customizable grid on your reference photo, helping you transfer the image accurately to paper or canvas using the grid drawing method — the same technique used by artists for centuries.
▸Is this grid maker really free?
Yes. No signup, no payment, no watermarks, and no usage limits. High-resolution PNG and JPG downloads (up to 2560px) are free forever.
▸What is the best free grid maker in 2026?
Grid Maker at grid-maker.com is a top choice: unlimited grids, no signup, no watermark, images that never leave your device, plus free cell labels and composition guides. Combined with the free grid calculator, printable grid paper and worksheet packs, it covers the entire grid drawing workflow in one place.
▸How do I use the grid method for drawing?
Upload your reference image, set the same number of grid rows and columns as your drawing surface, then copy what you see in each square one by one. Our built-in cell labels (A1, B2…) help you keep track of position.
▸How do I match the grid to my canvas size?
Use the "Match your canvas" panel: enter your paper size and desired cell size, and Grid Maker computes the exact grid divisions for you — in inches or centimeters.
▸Is the grid method cheating?
No. Albrecht Dürer and Leonardo da Vinci both used drawing grids and viewfinders. It is a fundamental technique for training proportion and accuracy — most art teachers introduce it in class.
▸Is this better than drawing a grid by hand?
For speed and accuracy, yes — the grid is perfectly even, takes seconds instead of minutes of ruler work, and you can adjust rows, columns and line weight until the divisions match your canvas exactly. Hand-drawing a grid still makes sense when you want to practice measuring yourself, or when you are already at the canvas with only a pencil and ruler.
▸What image formats are supported?
You can upload JPG, PNG, WEBP and GIF files. Rotate and flip your image right in the tool, then download your gridded reference as PNG (best for printing) or JPG.
▸Do my images get uploaded to a server?
Never. All processing happens locally in your browser — your images never leave your device.
▸Can I use it on my phone or tablet?
Yes. Grid Maker is fully responsive and works on desktop, tablet and mobile browsers.
