Drawing
Find the line before committing it.
For portraits, studies, and careful copies on paper, use a compact grid to locate key contours without losing the gesture of the whole image.
Best for: paper studies, portraits, sketchbooks

The grid method
Transfer proportion one measured square at a time.
A grid gives each part of a reference a fixed place. Match the same number of rows and columns on your drawing surface, then work cell by cell.
- 01
Choose a reference
Open a JPEG, PNG, or WebP image directly from your device.
- 02
Set the grid
Adjust rows, columns, line color, opacity, or visibility until the image reads clearly.
- 03
Copy with confidence
Use the same grid on paper, canvas, or a wall, then compare one square at a time.

A quieter way to look closely.
The grid is not a filter. It is a calm way to notice where an edge enters a square, where a shadow changes direction, and what belongs together.
One editor, three surfaces
Keep the reference stable while the drawing changes scale.
Canvas
Build a larger painting from a smaller source.
Use a consistent row-and-column count to carry the placement of a subject from a screen reference to a stretched canvas.
Best for: painting studies, scaled compositions
Mural
Keep distant marks accountable.
A clear overlay makes it easier to divide a large wall into manageable areas before you start drawing at arm's length.
Best for: walls, signage sketches, large-format work
Private by design
Your reference stays on your device.
Grid Maker decodes and draws your selected image in this browser. No account or server upload is needed for the current editor.

Questions, answered
A simple tool should be easy to trust.
Which image files can I use?
Choose a JPEG, PNG, or WebP reference image.
What can I adjust?
You can change grid rows, columns, line color, opacity, and visibility. You can also rotate or crop the reference before export.
Will the image be stretched?
No. The editor keeps the image proportion intact. Cropping is an explicit choice when you want a different frame.
Can I download the result?
Yes. Download a PNG that matches the current editor preview, including the visible grid.
