Ram your images into CSS sprites with Rambo

Project description

A command line sprite tool for smashing your images into sprites.

Includes pypacker, written by Joe Wezorek.


  • Automatic support for multiple sprite resolutions (based on folder names)

  • pngcrush for a low-fat diet

  • Produces an HTML test page so can preview your sprites

  • Python, so it’s blazing fast

Set up your images

You’ll need to drop your sprite images in a sub-folder for each pixel aspect ratio.

Eg, sprites/
      foo/           (the 1x has no prefix. Your sprite will be called this.)
      foo-0.75x/     (smaller than 1x for poxy androids. Use the same base-name `foo`)
      foo-1.5x/      (android pseudo-retina)
      foo-2x/        (true retina)


pip install rambo

Then run rambo from the command line:

rambo --input "images/sprites" --output "images" --csspath "css" --cssfile "_sprites.scss" --sasspath "sass/sprites" --testpage_dir "site" --testpage_name "test_page.html"


-h, --help                show this help message and exit
--input INPUT             Input directory, images/sprites
--output OUTPUT           Output directory, images/
--cssfile CSSFILE         CSS filename, _sprites.scss
--csspath CSSPATH         CSS output path, css
--sasspath SASSPATH       SaSS output path,  sass/sprites
--testpage_dir TEST_DIR   Cheat sheet dir, site/
--testpage_name TESTPAGE  Cheat sheet, cheat_sheet.html
