This tool is a free online alternative for TexturePacker. You can use it to pack sprite sheets, including data formats for Phaser, PixiJS, CSS and LESS.
Simply drag & drop your sprites into the main area and download the created .png files.
TexturePacker is a professional tool for game developers and web designers.
A sprite sheet packs many small images into one larger image, along with a data file that records where each sprite sits. A game or website then loads a single texture instead of dozens of separate files, which means fewer network requests, less texture memory and faster rendering. Animation frames, user interface icons and tile sets are the usual candidates. For the longer explanation, watch what is a sprite sheet.
Drop your images into the area above and this sprite sheet maker packs them into a single .png, then writes the matching data file. The available output formats:
Choose a compact, horizontal or vertical layout, set the padding between sprites, and download the sheet and its data file together.
The packing runs entirely in your browser. Your images are never uploaded to a server, so you can pack artwork you would rather not hand to a web service. There is nothing to install and no account to create.
Need trimming, multiple texture formats, hardware texture compression or a command line build step? Those live in the desktop version, TexturePacker. For a walk through the concepts, read how to create sprite sheets.
