Doohly Player supports 4 main image file types; jpg, jpeg, gif and png, again each one has benefits and drawbacks of being used in digital signage. These 4 file types are supported due to their popularity and ease of use.
Firstly, jpg and jpeg are the same thing, the filename has changed due to Microsoft having a limited file type length in early computing days but this has since been changed. Depending on your business type, you may already have access to a large library of jpg files. Jpgs are generally able to be compressed to take up a very small amount of space, but the compression leads to the files becoming pixelated and blurry.
Gifs are a great type of content to use for digital signage, but they are quite limited in that it only has a limit/range of 256 colours. This limitation also acts as a benefit in this case though as the gif file type is able to be made incredibly small and take up a minimal amount of space. If you plan on using a gif, we do recommend looking at converting to an mp4 as it will have smoother playback.
Png is quickly becoming the standard file type for online images thanks to its high colour depth and built in transparency. Files saved as png files can also be shrunk to quite small file sizes. In saying that, they can also become quite large if using photos or artwork.
Image file types, in a similar manner to video file types have best practices and use cases. Your particular digital signage plans and goals will partially dictate the type you select for your images.
If you plan on using photos and artwork, we recommend using jpg and ensuring that the content is saved in the correct size to fit the digital screen. If it needs to be compressed image quality will be impacted harshly. On the other hand, if you’re needing to use a digitally created image, we recommend the png file type. Finally if you need to use an animation and not a video, your best option is to use gifs, although we do still recommend converting gifs to mp4.
