Custom images and buttons pixelated on preview or publish

May 25, 2014

When I place any image, whether it be PNG or JPG, it comes out incredibly low quality and pixelated when I publish or preview it. The images look fine in Photoshop or in Storyline when I'm working on the course, but it becomes pixelated in preview or publish. I'm not sure why this is happening?

Hi Sam,

JPEG is a lossy format, and in most cases highly compressed. It is better to use PNG which also maintains transparency.

When going with a JPEG try not to change it's properties within Storyline too much, as the file may essentially get recompressed inside your story (hence introducing artifacts as in your screenshot above).

Also be sure to change the default Storyline compression level before publish by going to "Publish-->Quality-->Custom-->Image Quality : 100%".

Hope this helps,

Hi Sam,

It should look something like this:

If you're not seeing that, it may be an issue with the file, its location, or the installation. 

Please make sure that you're working with a local project file when you modify or publish your project. If you're working on a network drive, or any other external storage, that might be causing the trouble. 

  • Work on your local drive (your C: drive). Working on a network drive or a USB drive can cause erratic behavior, including file corruption, loss of audio, and other unexpected behavior. 
  • You should also make sure the directory path to your project files and your published output is less than 260 characters (for example C:\Articulate).
  • Avoid using special characters, accents or symbols in your file names (this includes spaces and underscores).

Additional information regarding "Naming Files, Paths, and Namespaces" in Windows operating systems can be found in the following Microsoft article.

It may also help to check your DPI settings.

If you're already working locally, and since you've already installed Update 5, it may help to run a quick repair:

If you still have trouble, it might help to share a .story file here that contains one/some of the images that appear this way when previewing or publishing.

Yup I found that exporting certain images larger helped. The compression issue Sam had didn't change for me after pushing the slider to 100%. I had to import a larger image. Weird though because none of my larger pngs did that. Guess it may because there's more color variation in those graphics. The image I was having trouble with was a little more "flat".
