Frequently Asked Questions
Is work saved automatically?
Refresh may clear the canvas unless the tool adds local storage—export often.
Can I import a background image?
If the page supports underlay upload, use it; otherwise paste screenshots via beautifier tools.
Does it support layers?
This board is single-layer simplicity; use Online PS for layered edits.
Is there a tablet pressure?
Basic builds ignore pressure; lines use fixed width per setting.
Can I collaborate live?
Standard mode is single-user; share exported PNGs instead.
Are brushes unlimited?
All tools are free; canvas size may be fixed to screen resolution.
