See how to get PNG image files from a layered PSD in Adobe Photoshop.
Why you’d save your file as a PNG from a Photoshop document.
PNG (portable network graphics) files are lossless compression files that work well for simple graphics and duotone icons. If you have a PSD (Photoshop document) file in which you’ve created a chart, line drawing or another simple raster image, converting it to a PNG file format is ideal for retaining image quality in a small file size before sharing your graphic.
How to convert to PNG format from a PSD image.
Select File and choose Save As. From the options, select PNG.
Choose an interlace option. The None option gives you the image only when the download finishes. Selecting the Interlaced option makes the download time seem shorter, as it shows you a low-res version of the image as it downloads, but it gives you a larger final file size.
You now have a PNG file ready to use online. You can also import it into different Adobe systems, like Adobe InDesign, to add to other work.
