Making a tileset in LibreSprite
LibreSprite 1.3 has no tilemap layers (Aseprite added those later), but it has the two things you really need for tiles: Tiled Mode, which shows a tile repeating around itself so seams are obvious, and a grid that keeps every tile aligned.

Short answer
Can you make tilesets in LibreSprite?
Yes. Draw single seamless tiles with View → Tiled Mode (Shift+T), then lay them out on a canvas divided by a 16 × 16 or 32 × 32 grid (View → Grid → Grid Settings, Shift+G) and export one PNG. Build the actual level in a map editor or game engine (Tiled, Godot, Unity), which read that PNG as a tileset.
1. Draw a seamless tile
New sprite the size of one tile
16 × 16 or 32 × 32 (Ctrl+N).
Turn on Tiled Mode
View → Tiled Mode → Tiled in Both Axes (Shift+T). The tile now repeats around the canvas, and strokes that cross an edge continue on the opposite side.

Paint across the edges until no lines or repeated blobs stand out. Tiled in X Axis or Y Axis only is useful for tiles that repeat in one direction (walls, ground strips).
Shift to check the inside
Edit → Shift → Left/Right/Up/Down moves the whole tile with wrap-around, bringing the edges into the middle where they are easier to judge.
2. Lay out the tileset
Make the sheet canvas
A new sprite sized in whole tiles, for example 128 × 128 for 8 × 8 tiles of 16 px.
Set the grid
View → Grid → Grid Settings: width and height 16. Show it with Shift+G and turn on Snap to Grid (Shift+S) so selections and moves land on tile boundaries.

Copy each finished tile (Ctrl+A, Ctrl+C), paste into the sheet and drop it into a grid cell. Or draw directly in the cells; select one cell and use Tiled Mode on a copy (New Sprite from Selection, Ctrl+Alt+N) to check its seams.
Plan variants
For terrain: a centre tile, edges, outer corners, inner corners, plus two or three variations of the centre so large areas don’t look stamped.
View → Grid → Selection as Grid sets the grid from a rectangular selection: handy when tiles don’t start at the top-left corner.
3. Export and use it
- File → Export (Ctrl+Alt+Shift+S) as PNG at 1×. Keep the
.aseas your editable source. - Tiled (map editor): Map → New Tileset → “Based on Tileset Image”, tile size 16 × 16.
- Godot 4: add a TileMapLayer, create a TileSet with tile size 16 × 16, drag the PNG into the TileSet panel and let it create tiles automatically. Set texture filtering to Nearest (how).
- Unity: import as Sprite (Multiple), slice by cell size in the Sprite Editor, then use a Tile Palette.
Avoid lines between tiles in the engine
Thin gaps or bleeding between tiles usually come from texture filtering or mipmaps, not your art: use nearest filtering, no compression, and if needed 1–2 px padding between tiles (our sprite sheet tool can add it).
FAQ
Does LibreSprite have a tilemap editor?
No tilemap layers or tile palettes in 1.3. Use Tiled Mode and the grid for the art, and a map editor or engine for the level.
What tile size should I use?
16 × 16 is the classic size and quick to fill a game with; 32 × 32 gives more detail. See the canvas size guide.
How do I check a tile repeats without seams?
Tiled Mode (Shift+T) shows it repeated around itself; zoom out (1 or 2) to see a larger area.
