White-filled PNGs are includes with each image download. These are perfect for layering in programs like Word and Powerpoint, or Pages and Keynote because there is no need to erase lines (so no need for photo editing software). This format is also perfect for layering on top of digital designer paper. Print out your image layered on top of the digital paper, and then color.
The images also come in two other formats: transparent PNGs—perfect for layering on top of digital designer paper for paper piecing. (Layer a transparent PNG on the digital paper, and print the paper and digi stamp at the same time. Then cut out the parts of the image you would like to paper piece.
And the third format is the familiar JPG. A JPEG will always have a white box because a JPG does not support transparent properties.
Sentiments come in two file formats: JPG and PNG.
Here are the differences between file formats:
The image above shows the three different file formats placed over a digital paper I created. The .jpeg has a white box because there is no transparency. PNGs allow transparency, so you can layer the completely transparent .png over digital paper, print it out and use it for paper piecing. (Instead of running designer paper through your printer.)
White-filled .pngs are perfect to layer over digital paper that you want for a background–you can print it out and you still have a white image to color. Only the image is filled with white; the background is transparent. This is also perfect for layering images to create a scene as I did with the two images in the lower left corner.
