Frequently asked questions
Is Ontools a free alternative to paid design apps?
For everyday social media graphics, posters, cards and simple logos, yes. It is free, needs no account and adds no watermark. It is intentionally simpler than professional design software.
Where is my design saved?
Automatically in your browser on this device. To move a design to another computer, use File → Save project file and open it there.
What is the maximum canvas size?
8000 × 8000 pixels. Very large canvases may be slow on phones.
Does it work on mobile?
Yes. The panels move to the bottom of the screen on phones. A larger screen is more comfortable for detailed work.
