Free pixel art and tileset editor, no account needed. Opens a sprite, an animation or a 16-tile Wang autotile set in an editor inside the chat, lets you edit it by hand (layers, frames with onion skin, tiling preview), and returns the edited PNG.
Scored across 6 tools
Each tool has a largely distinct role: get_sprite is read-only state retrieval, open_editor and open_full_editor are split by feature tier (compact vs layers/selection/animation), and load_art/save_art are card-only callbacks. The only real overlap risk is choosing between open_editor and open_full_editor or between open_tileset_editor's many input modes, but descriptions spell out the distinctions well.
All names are snake_case verb_noun (get_sprite, load_art, open_editor, save_art), with open_full_editor and open_tileset_editor following a predictable verb_noun_qualifier pattern. No convention mixing.
Six tools is tightly scoped to the editor's purpose: read state, open one of three editor types, and the two internal card callbacks. Every tool earns its place with no filler.
The surface covers the core lifecycle: open an editing session, read pixel/session state, and persist edits, across sprite, full-feature, and tileset editors. Minor gaps exist around exporting/saving to a file destination or listing/deleting existing sessions, but the PNG URL from get_sprite largely covers retrieval.
Returns the current state of a SpriteForge edit session: a preview image, its size and palette, how many edits were saved, and a PNG URL with the exact pixels at 1x (add &frame=N for another frame). With include_pixels it also returns the palette-index grid. Read-only.
Inputs: session_id (required), include_pixels.
Loads an edit session's sprite into the SpriteForge editor card. Only the card calls it.
Inputs: session_id (required).
Opens pixel art in SpriteForge's compact pixel editor - pencil, eraser, fill, colour picker, palette, undo and animation frames - as an interactive card where the app shows them, and returns an edit link (the same editor in a browser) and a session_id. No account needed. One source at most: png_base64 (an existing PNG), art (palette + index grid), or neither for a blank width x height canvas. Max 128x128 pixels and 256 colours. The user's edits save to the edit session automatically.
Inputs: art, name, width, height, +2 more.
Opens a sprite in SpriteForge's full pixel editor - layers, selection and move, line/rectangle/ellipse, mirror painting, brush sizes, animation frames with onion skin and playback, palette tools - as an interactive card where the app shows them, and returns an edit link that opens the same editor in a browser. One source at most: session_id (an edit session that's already open, or an edit link), png_base64 (an existing PNG), art (palette + index grid), or none for a blank width x height canvas. Max 128x128 pixels and 256 colours. The user's edits save to the edit session.
Inputs: art, name, width, height, +3 more.
Opens a tileset in SpriteForge's tileset editor as an interactive card where the app shows them, and returns an edit link that opens the same editor in a browser. For a Wang autotile set (16 tiles; tile i is drawn where the map cells at its corners are painted, NW=1 NE=2 SW=4 SE=8, so tile 15 is the solid base; sets SpriteForge derives add 4 variants of tile 15 as tiles 16-19, mixed into painted floors) the user paints a small map to see the tiles chain, draws on the map or on single tiles, and edits the base texture, which re-derives the edge tiles (tiles drawn by hand stay); a platformer set (49 tiles) is edited tile by tile. With session_id it opens a tileset that's already in an edit session, and kind (wang = flat floor terrain, wall, iso) switches that Wang set's preview, keeping its tiles and the user's edits. Otherwise it makes a new set from kind (wang, wall, iso or platformer; default wang) plus palette + tiles (16 or 20 grids for Wang, 49 for platformer, in mask order), palette + base (a seamless square texture; the Wang tiles are derived from it as SpriteForge does), png_base64 (a tileset sheet or a texture), or size alone for a blank set. With png_base64 and no layout, a 16x1 or 20x1 image is a strip, a 4x5 one a sheet, and a square one is a 4x4 sheet when its tiles look like a Wang set in mask order (tile 0 empty, or nearly every tile's corners matching tile 15 where its mask has that corner and tile 0 where it doesn't), else a texture. The result says which view it opened and how it read the PNG. The user's edits save to the edit session.
Inputs: base, kind, name, size, +5 more.
