Rotate Pixel Art by Any Angle
Free pixel art rotation: turn a sprite by any angle the RotSprite way, with no blur and no new colours, or in 8 or 16 directions as a sprite sheet and GIF.

How to use the Pixel Art Rotate
- Drop a pixel-art sprite with a transparent background.
- Set the angle with the slider or a preset (positive turns clockwise).
- Keep RotSprite (clean) on, or switch to Plain nearest to compare; untick "Grow the canvas to fit" to keep the sprite's size.
- Tick Sweep and pick 4, 8, 16 or 32 directions for a full turn.
- Download the PNG (1× or 4×), or the sweep's GIF, sprite sheet and angles JSON.
Using it in your game
Sweep frames share one canvas size with the sprite centred, so keep the centre as the pivot. For a top-down car, ship or turret, pick the frame nearest the heading: index = round(angle / (360 / N)) mod N, with angles clockwise from the first frame. Scale up by whole numbers with nearest filtering (filter off in Godot, Point in Unity) so the pixels stay sharp.
Frequently asked questions
Why does rotated pixel art usually look broken?
A plain rotation picks one source pixel for every output pixel, so sloped lines break into uneven stairs and single pixels vanish or double up. A smooth rotation blurs the edges instead and invents in-between colours your palette never had.
How does this tool rotate a sprite?
With the RotSprite method: the sprite is scaled up 8 times with Scale2x, which rounds diagonals using only the colours already there, then rotated with nearest neighbour and scaled back down, each pixel taking the most common colour of its 8×8 block. Lines stay continuous, quarter turns are exact, and the canvas grows so nothing is cut off.
Does it add colours or soft edges?
No. Every pixel of the result is one of your sprite's own colours, and transparency stays hard (fully on or off), so the rotated sprite drops straight into the same palette. The note under the controls shows how many colours it used.
Can I make 8 or 16 directions?
Yes. Tick Sweep and pick 4, 8, 16 or 32 directions, starting from the angle you set. Every frame shares one canvas size and stays centred, so a top-down car, ship, turret or projectile can be played as a sheet, a GIF or by angle from the JSON. To draw a character from its other sides (front, back, side), use the AI 8-direction sprite generator instead.
Is anything uploaded?
No. Everything runs in your browser, with no account and no limit. From Claude Code or Cursor, the free rotate_pixel_art tool on the Voidless MCP server does the same.
