Frequently Asked Questions

What features does the online drawing tool support?

You can draw freely with the pencil tool and correct specific areas with the eraser. Brush color, size, and opacity can be adjusted freely, and undo (Ctrl+Z) and redo (Ctrl+Shift+Z) are supported. Canvas size and background color can also be set as desired.

What formats can I save my drawing in?

You can save in PNG or JPG format. PNG supports transparent backgrounds and saves without quality loss. JPG has smaller file sizes and is suitable for photos, with quality adjustable from 10–100%. If you need a transparent background, you must choose PNG format.

Do you support layers?

The current version supports only a single layer. Instead, undo/redo lets you manage up to 50 steps of work history. For complex layer work, professional software like Adobe Photoshop or GIMP is recommended.

Can I use it on a tablet or smartphone?

Touch input is supported, so you can draw with your fingers on tablets and smartphones. On mobile, the canvas size is automatically adjusted to 400×300 to fit the screen. Devices with stylus pen support enable even more precise drawing.

Digital Drawing Basics Guide

If you're starting digital drawing, getting familiar with brush size and opacity controls is important. Layering strokes with low opacity creates watercolor-like effects. Setting the background to transparent and saving as PNG creates assets for compositing over other images. Make good use of the undo shortcut (Ctrl+Z) to work without mistakes.
