Tesseile — Pixel Art Studio

Hurtorius

About this app

Tesseile is a full offline pixel-art studio for your phone: no account, no subscription, no connection, nothing watching over your shoulder. Desktop depth - drawing, animation, filters, tilemaps, palettes, export - with nothing between you and the grid.

NO ARTIFICIAL LIMITS
- Type custom canvas sizes, bound by your device instead of a fixed cap
- Type brush sizes, export scales, and values within device-safe bounds
- 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
- Device-safe brush sizes, round or square

FILTERS & EFFECTS
- 17 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
- Device-bound 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 and live playback preview

COLOR
- HSV picker with shading-ramp and color-harmony generators
- 42 built-in palettes, including 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
- Preview image, sprite-sheet, project, Tiled Pack, and backup imports before writing, with palette-aware image conversion

TILEMAPS
- Turn any drawing into a deduplicated tileset
- Paint levels with the tile pen
- 4-way terrain auto paint for N/E/S/W tile transitions
- Update a tileset tile from any canvas selection and every placed copy refreshes
- Export tilesets and maps as PNG, CSV, TMX, JSON, or a Tesseile Tiled Pack ZIP; compatible layers with the same tile size reopen as editable tilemap layers

EXPORT
- PNG at 1x-32x scale
- Animated GIF and APNG
- Sprite sheets with JSON metadata
- Game pack ZIPs with sheets, palettes, source .tesseile without references, and tilemap packs
- Lossless .tesseile project files you can reimport anywhere

WORKSPACE
- Seamless tiled drawing: paint, fill, shape, and effect strokes wrap across edges
- Searchable command palette for every tool, filter, and command
- Navigator minimap with a live viewport you can drag to pan
- Library backup and reviewed restore for projects, stamps, palettes, and settings
- Saved reference images reopen and never export
- Searchable in-app guide
- Multiple documents open at once with a tab bar

TOUCH-FIRST
- One finger draws, two fingers pan and zoom
- Two-finger tap to undo, three-finger tap to redo
- Long-press to pick a color from the canvas
- Deep undo history and automatic saving

PRIVATE BY DESIGN
Tesseile has no internet access, no storage/media permissions, no Android backup, and no data collection. Your art stays on your device unless you export or share it. No accounts, no ads, no analytics, no subscriptions.
