ToolwebHow to use this tool
- Set the canvas dimensions and draw with pencils, shapes or fill. Adjust zoom and the grid.
- Use layers, opacity, symmetry and selection movement; duplicate frames and preview them.
- Export PNG, a sprite sheet or GIF, or save an editable project JSON file.

Keep editing reversible
An undo state is recorded after a stroke, allowing erase, fill and selection movement to be reversed. Selections affect the active layer. Use layer arrows to reorder and opacity controls to change blending; hidden layers are omitted from the exported picture.
Project files versus flattened pictures
PNG and GIF are flattened pictures and do not retain editable layer structure. A project JSON preserves canvas, frames and layers for reopening. Work is not automatically written to persistent browser storage, so download a project before leaving. GIF uses a fixed quantized palette and can differ in color from a PNG.
Common questions
Can I reopen an older Toolweb project?
Supported Toolweb pixel-project formats are validated before loading. A damaged file or one exceeding size and layer limits is rejected while preserving current work. Export an image from another editor when its native project format is unsupported.
