Notes

Notes

Important points are grouped with reasons so you can make decisions before using the tool.

Before editing

Decide where the finished image will be used

Choose the original ratio or a square, landscape, portrait, OGP, A4 or custom canvas first so you do not need to rebuild the layout later.

While editing

Controls change with the selected object

Select an object and use Open settings at the upper right. Settings appear on the right on desktop and below the canvas on mobile. Choose a tab to change the settings shown.

Before export

Deselect objects and review the finished image

Check readability, hidden areas and stacking before choosing a format. Keyboard controls are available from Help in the editor.

Mobile

Adjust the settings height

On mobile, drag the handle above settings to change its height. Swipe it firmly down to close; reopen settings from the control below the canvas.
