Open your reference on the iPad
For iPad grid drawing, open this page in Safari or another iPad browser. There is no App Store app to install and no account to create. Tap the photo upload area and use the system picker to select a reference from Photos or Files. Your photo stays on the iPad while the browser creates the overlay.
This page starts with an eight-by-eight grid and numbered labels. Tap the row or column field to enter a different count. If you want equal-sided cells, turn on Square cells; the column count will then determine their size and the rows will be automatic.
Use landscape orientation when you want more room beside the settings. You can also hide browser controls where your browser supports it to give the page more screen space. On a narrow display, the preview appears below the controls, so scroll down after making an adjustment to inspect the result.
Adjust with touch and save a copy
Make small slider changes, then check a recognizable edge such as a jawline or roof. If lines disappear against dark areas, choose a lighter color rather than increasing width immediately. Numbered labels help you return to a cell after scrolling between the settings and preview.
When you are ready, tap Download PNG. Depending on your browser and settings, the file may open in a preview or appear in the download list. Use the browser download controls to find it in Files. If an image preview or the Files share menu offers Save Image, use that option to put a copy in Photos. The exact menu wording can vary.
Keep the saved image open beside your drawing, or switch between it and your sketching app. This page makes a gridded reference image; it does not add a drawing layer to another app. If a selected photo format cannot open, export a JPG or PNG copy and try again.
