Time for action - compress media files

Before we share our work, let's make our project as small as possible:

  1. First, compress the images in the project. From the Edit menu, select the Compress images option to display the JPEG Quality dialog box.
  2. Set a quality number between 0 and 100. In my example, I'll use 80.

    Tip

    Choosing a higher JPEG quality creates a clearer image, but it also creates a bigger file size.

  3. Click OK to have Scratch compress any JPEG images. When finished, Scratch will report the number of images it compressed. Click OK to accept the message.
  4. Next, compress the sounds. From the Edit menu, select compress sounds to display a list of compression options.

  5. Select the sound quality you want and click OK. Normal should work in most cases.

    Tip

    Higher quality settings create the best sound quality, but it also creates a bigger file size.

  6. When finished, Scratch displays the number of sounds it compressed. Click OK to accept the message.

What just happened?

When we share our projects on the Web, we want to make our project as small as possible so that people can play our games, watch our stories, and experience our animations in a friendly way.

Hopefully, we will have chosen values that provide an acceptable level of quality for our media while enabling a positive experience for our users.

Share!

If you want your Scratch project to display a certain way, make sure you set the stage before you share the project. For example, if you need certain sprites to be hidden when the game loads, hide the sprites before you share the project because Scratch will remember its state.
