Smudge details

Drawing spreads nearby marks onto a separate Smudge layer. Turning off stops new smudge; existing marks remain.

Choose a stroke; expand Edit to adjust its defaults.

Follow stroke near edges

When zoomed in, guided and straightened lines follow in the outer 18% of the usable drawing area. Move outward to speed up; hold to continue, pull back to ease to a stop, or lift to stop immediately.

Canvas

Smooth fine lines when zoomed out

Uses cached half-size previews to preserve fine lines. Artwork and exports stay unchanged.

Resolution

Print quality

Keeps printed size and lineweights. Anchored top-left; smaller sheets crop artwork. Applying a change clears undo.

Preferences are remembered in this browser. Reset also clears both custom grid slots; current drawing size and resolution stay unchanged. Use Apply paper size to change them.

Selection & editing

Drag a rectangle; set a circle by center and radius, or an ellipse by three parallelogram corners, just like the drawing instruments. Wand selects a connected area; Polygon uses tapped corners. Hold Shift to add or Alt to subtract when starting a selection. Use Move / Transform to move, scale, or rotate the selected pixels. Edits affect selected layers. Done clears the selection; choosing a drawing tool keeps the selection as a drawing mask. Copy/Paste uses this app’s clipboard.
