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

How do I use this tool?

  1. 1.Upload and frame the photo

    Choose your image and the canvas shape. Review the edges before adding guide lines so you do not accidentally work from an unwanted crop.

  2. 2.Choose the line arrangement

    Start with a vertical and horizontal center division. Adjust rows and columns for more regular lines, or choose an available composition guide.

  3. 3.Save the photo with lines

    Set the line appearance and download the PNG. Check the result before sharing it as an alignment or composition reference.

Before I download

Can I add just horizontal lines?

Set the custom grid to one column and multiple rows. For only vertical internal divisions, use one row and multiple columns.

Can I keep the lines editable after export?

No. The 2400-pixel-wide PNG combines the image and lines. Keep the unmarked original if you may need to change the guide later.

Use regular lines for repeatable measurements

A 2x2 layout creates four regions and marks the midpoint in each direction. A 3x3 layout divides the frame into thirds instead. These evenly spaced guides are useful when comparing positions; they do not require manually measuring each pixel of the source image.

Choose another editor for annotations

If your task is to circle an object, underline a word, draw an arrow, or connect two arbitrary points, regular grid lines are the wrong shape of tool. This page handles grid and composition guides. A freehand annotation editor is needed for individually placed marks.
