Pixel Art Editor - Dotsmith

Dotsmith is a pixel art editor for sprites, icons and small animations, made so your work stays put: undo survives closing the app, and two fingers never leave stray lines on the canvas.

▶ UNDO THAT SURVIVES CLOSING THE APP
• Every stroke, fill, shape, move, layer or frame change is one undo step.
• The newest 100 steps are saved inside the project file, so Undo still works after you leave the canvas or close the app.
• Autosave runs about 2 seconds after you stop drawing.
• Deleted projects go to Trash and stay there until you delete them forever, with Undo right after you delete.
• Each project keeps up to 10 earlier versions; restoring one makes a copy.

▶ TWO FINGERS NEVER DRAW
• If a second finger lands within a quarter second, the stroke you started is removed and the touch becomes zoom and pan.
• Two separate strokes are never merged into one undo step.
• Tap with two fingers to undo, with three fingers to redo.
• When you stop pinching, the zoom settles on a whole number of screen pixels per cell, so every pixel is the same square.

▶ DRAWING TOOLS
• Pencil and eraser with brush sizes 1–4 px. Fast drags leave no gaps.
• Fill, line, rectangle and ellipse (outline or filled) and an eyedropper.
• Mirror drawing left–right, top–bottom or both ways.
• Select an area to move, flip, copy, cut, delete or paste it, also onto another frame or layer.
• Up to 8 layers with show/hide, lock, opacity, rename, duplicate, merge down and reorder.

▶ ANIMATION
• Up to 256 frames in a frame strip: add blank or duplicated frames and hold any frame ×1 to ×8.
• Frame rate 1–30 fps, loop and a full-screen preview.
• Onion skin shows up to 3 earlier frames in red and the next frame in green. It is never exported.

▶ EXPORT
• PNG at ×1 to ×32 (up to 4096 px), with optional grid lines from ×4.
• Sprite sheets as a grid, row or column, with padding and optional frame data (.json).
• Animated GIF at ×1 to ×8 (up to 1024 px).
• Nearest-neighbour scaling keeps every pixel sharp, with no blur.
• Save to Photos (Pictures folder) or share. The file is checked on disk before the app says it is saved.

▶ COLORS AND IMPORT
• Preset palettes (Default 32, Gray 8, Pastel 12, 1-bit), .hex and .gpl palette import, .gpl export, or a palette of 4 to 64 colors taken from an image.
• Turn a photo into pixel art: pick 16 to 128 px on the long side, fit or crop, then keep the colors, reduce them to 4–64 or match your palette.
• Enlarged pixel art (PNG, WebP, GIF or BMP up to 2048 px) is detected and can be opened at its true size.
• Canvas from 1 to 256 cells on each side, any width and height: 32 × 19 works too.
• Share a project file (.pxs), or back up the whole library to one .zip file and restore it later.

▶ GOOD TO KNOW
• Limits: canvas up to 256 × 256, up to 8 layers and 256 frames within a 32 MB pixel budget. The app tells you when another frame or layer would not fit.
• GIF holds up to 256 colors. Extra colors are merged, and partly transparent pixels become solid or clear.
• Up to 100 undo steps (8 MB) are saved with a project. Redo is not saved.
• Your projects are kept in the app and are not uploaded. Files leave the app when you save them to Photos or share them.
• Imported photos are processed on the device and are not stored; the project keeps the resulting pixels.
• On some older phones, the first save to Photos asks for storage access.
• Ads appear on the projects screen, and sometimes when you return to it after an export. Never on the canvas.

Recent changes:
Draw sprites frame by frame while Onion skin tints up to three earlier frames red and the next one green. Pixelate shrinks a photo to 16–128 cells on its long side, and Export hands you a PNG, a Sprite sheet or an animated GIF scaled without blur.
