A 4×4 drawing grid keeps the portrait in proportion.

How do I use this tool?

  1. 1.Choose the underlying image

    Upload the picture you want to study and select its output frame. Check the visible boundaries before deciding on a guide.

  2. 2.Select a useful overlay

    Use the custom 4x4 grid for repeated cells or choose a composition preset. Adjust the line color, opacity, and width to keep the subject readable.

  3. 3.Export the visible result

    Download the PNG once the grid serves your task. The photo and overlay are saved together as a single reference image.

Before I download

Is the overlay a separate transparent PNG?

No. This workflow exports the whole canvas with any uploaded photo and the grid included. It does not provide a transparent grid layer.

Can I customize every line independently?

No. Appearance settings apply to the guide as a whole, and custom-grid spacing follows row and column counts. There is no per-line editing or freehand annotation.

Choose between cells and composition lines

A custom grid divides the canvas into repeated regions and suits position checks or drawing reference. Thirds, diagonal, and other composition guides answer different framing questions. Switching the guide changes the reference structure, so use the one that matches what you are trying to compare.

Keep the overlay subordinate to the image

Strong lines make a grid visible but can draw attention away from the subject. Start with moderate opacity and inspect both light and dark areas. A subtle grid is usually easier to study at close range; a bolder one can read better in a small shared preview.
