The PRN file extension is associated with the PostScript graphic programming language developed by Adobe. PostScript is primarily designed to present publication-quality text. A PostScript file consists of a set of images of pages. These pages can include graphics, or in fact consist entirely of graphics.
As a graphic language, PostScript is basically vector-based rather than bit-mapped. Thus, it's easy to draw a square or a star, or even a filled polygonal region. But it's rather unnatural, in PostScript, to define a rectangular region in which every pixel has an assigned color. If a highly detailed bit-map image is needed, it is often computed in another format, such as GIF, and then "imported" into the PostScript format.
The PRN file extension is associated with the SmartWare programming platform that uses Faircom database engine also including word processor, spreadsheet editor and communication modules. The .prn file contains text printed to file stored on hard disk.

DESIGN II (Microsoft Windows)
Those who work with image editing applications know that they need Photoshop to work at ease. It is true that online there are free alternatives to edit your photos, but the problem comes when someone sends you a file with a .PSD extension. Do not be scared if this is the case, it is not a virus but the specific format of the Adobe photo processing tool.
If you do not have the corresponding software we will show you how you can open and work .PSD files from the Internet.
More than one would like to learn some Photoshop to remove those years of more or else do a little hooligan by modifying a photo. But those looking for a free alternative that allows them to work with .PSD files have it easy with the online tool Photopea.
Just open it you will find an interface very similar to the Adobe program. If you are a veteran or have worked with the previous versions of the software, it will not take long to get the controls, which are very simple and clear. All you need to do is open a file and import the PSD to edit it from the network. The best thing about this free tool is that it allows you to use keyboard shortcuts such as ctrl + alt + z to redo or ctrl + Z to undo, but in contrast you can not create texts to your liking. Being an Internet tool does not have all the fonts or brushes (if you had them) to create the texts you want.
If you think about it, it's not that bad either. Once you finish with the Photoshop file you can export the image in a readable format to work with it. You can open it with another program that you have installed, such as Word or PowerPoint, and add the sentences you are missing with the style that you like the most.
Other alternatives to edit images
Now that you know Photopea, you just need to get down to work to learn how to edit photos. In addition, you just need a little practice and fretting you will get to do with the basic parameters of the program. Best of all, all the programs share the same categories and only change the interface slightly, so it will not be difficult to get used to them.

is used by following type(s):
Default for .pages type: iWork document
This suffix is related to iWork documents, openable solely in Apple iWork.
To open it in Windows, you only need one thing: a file-sharing compressor, such as WinRAR, 7Zip or WinZip, whichever you like the most, are all free. If you already have it installed, we continue.
All you have to do is take the file, which will be something like "xxxx.pages", and change the extension (right click and then "Rename"). You only have to delete the suffix and put ".zip" instead -without the quotes-, in such a way that "xxxx.zip" would remain.
When we change it, it will automatically become a .zip compressed , which we can open without any problem with the compressor we have downloaded before. And what will we have inside? Well, among many useless things we will have a .PDF that contains the text that was in the page document, and we can open it and read it without any problem.
You can read that PDF file from any operating system. As PDF that is, editing it is somewhat more complicated, like converting it to Word -without going through third-party websites, of course-, but at least you can read it and it will get you out of a punctual hurry.
