Tesseile — Pixel Art Studio

The omni pixel-art studio for your phone. Tesseile packs the depth of a desktop pixel editor — drawing, animation, filters, tilemaps, palettes, export — into a touch-first tool that works entirely offline. Pay once, own it forever.

NO ARTIFICIAL LIMITS
- Type any canvas size you want — bound only by your device, not a fixed cap
- Type any brush size, any export scale, any value — real custom numbers everywhere
- Open multiple documents at once and switch between them with tabs

DRAW
- Pencil with true pixel-perfect strokes (auto-removes jaggy L-corners)
- Eraser, dithering brush, and a shading ink that shifts colors along your palette ramp
- Spray / airbrush, blur, and smudge brushes
- Capture any selection as a custom stamp brush
- Lines, rectangles, ellipses with live preview — filled or outlined
- Bucket fill with tolerance, contiguous or global
- Dithered gradients, linear and radial
- Symmetry: vertical, horizontal, quadrant, and radial
- Stroke stabilizer for steady curves
- Any brush size, round or square

FILTERS & EFFECTS
- 18 live filters with on-canvas preview before you commit
- Brightness/contrast, hue/saturation/lightness, posterize, threshold, pixelate
- Blur, gaussian blur, sharpen, edge detect, emboss, outline, color tint
- Invert, grayscale, sepia — apply to a cel, selection, frames, layers, or the whole sprite

SELECT & TRANSFORM
- Rectangle, ellipse, lasso, and magic wand selections
- Add, subtract, and intersect modes with marching ants
- Cut, copy, paste, paste-as-layer, drag floating selections
- Flip, rotate, crop, trim, resize with anchor control

LAYERS
- Unlimited layers with opacity and 14 blend modes
- Lock, alpha-lock, hide, merge down, flatten, reorder

ANIMATE
- Frame-by-frame timeline with thumbnails
- Onion skinning with tinted previous/next frames
- Linked cels — hold a drawing across frames without copies
- Frame tags with forward, reverse, and ping-pong loops
- Per-frame timing, live playback while you draw

COLOR
- HSV picker with shading-ramp and color-harmony generators
- 12 classic built-in palettes: PICO-8, Sweetie 16, DawnBringer, AAP-64, Game Boy, NES, Endesga 32, Resurrect 64 and more
- Build a palette from any photo
- Import/export GPL, HEX, and PAL palette files
- RGBA, Indexed, and Grayscale color modes

TILEMAPS
- Turn any drawing into a deduplicated tileset
- Paint levels with the tile pen
- Export tilesets and maps as PNG, CSV, TMX, and JSON for Tiled and game engines

EXPORT
- PNG at 1×–32× scale
- Animated GIF and APNG
- Sprite sheets with JSON metadata
- Lossless .tesseile project files you can reimport anywhere

WORKSPACE
- Searchable command palette — every tool, filter, and command in one place
- Navigator minimap with a live viewport you can drag to pan
- Searchable in-app guide with visual demos of every tool and effect
- Multiple documents open at once with a tab bar

TOUCH-FIRST
