Sprite Sheet to GIF Converter

A sprite sheet is one image holding every frame of an animation in a grid. Tell the tool how many columns and rows it has, or how large one frame is, and it cuts the sheet into frames, left to right and top to bottom, and plays them.

The grid is guessed when the sheet opens: a strip of square frames, or a common size such as 16, 32 or 64 pixels that cuts through no drawing. Cells with nothing in them are skipped, so a half-filled last row does not make the animation blink.

• Speed: 8 to 12 frames per second suits most game animation; 24 is smooth, and 6 is choppy on purpose.
• Direction: play forward, in reverse, or there and back (ping-pong), which makes an idle or breathing loop from half the frames.
• Frames: click any frame in the strip to leave it out. A sheet with several animations in its rows can be cut down to one this way.
• GIF size: 2× to 8× enlarges with hard edges, so a 32-pixel sprite is still readable in a chat or on a store page.

An animated GIF is read into whole frames, exactly as a viewer would show them, with their original timing. Save them as a sprite sheet in one row, one column or a near-square grid, or as numbered PNG files.

A GIF holds at most 256 colours and no partial transparency. That suits pixel art well; for painted or photographic frames, the PNG sheet keeps every colour.
