What is a PDF File
It is the extension file used by Adobe Acrobat reader software. It is a document format used to save documents created with previous formats, for example DOC.
This format (Portable Document Format) is a type that was invented by Adobe Systems and perfected for more than 20 years.
It has become a standard for the exchange of electronic documents maintained by the International Organization for Standardization (ISO ). When converting any type of document to PDF, its appearance will be the same in all media.
However, unlike printed documents, these files can contain links and buttons that can be clicked, form fields, video and audio, and even programming to automate certain processes.
All this type of possibilities of including information or not is what each one of the different variants of the format supposes.
How to Open a PDF file
Currently most of the most popular and modern browsers are able to open any .PDF so you can view the document directly from it.
And yet, it is very likely that, like lots of people in the world, you have some third-party software installed on your computer just for that purpose.
The most common suspect is Adobe Reader, but when you find out about things like simply using your PDF reader you end up with unwanted Chrome extensions that collect your browsing data, you may start thinking about an alternative.
If you prefer not to download any other special program, we tell you how to simply use your web browser for that task.
When you open this file while browsing the web you do not have to worry about this, as the browser simply shows it in a tab.
But, when it comes to PDF on your disk or other devices, by default Windows 7,10 and all the versions usually asks for a specialized program and there you end up with Adobe Acrobat Reader or similar.
Open With Google Chrome
If you want all your PDF to open with Google Chrome, or Firefox, or Microsoft Edge, or the browser of your choice, you can activate a couple of very simple settings to choose the default application that will always read your files.
- Find a .PDF on your computer and right click on it. Select the option "Open with" and in the following drop-down menu click on "Choose another application".
- Browse the list of options and if the web browser you want to use does not appear there, scroll to the end and then select "More applications".
- If it still does not appear, go down and select "Search for another application on your computer". If you want to open all your PDFs with Chrome, surely this will be the way you will have to go.
- Now navigate to the path of your computer where the browser you want to use is installed. In the case of Chrome, the .exe is located in C: \ Program Files (x86) \ Google \ Chrome \ Application. Select the executable and then click on "Open".
- Finally, make sure to check the box "Always use this application to open the .pdf " so you only have to double click on the icon from now on.
The process is exactly the same always, the only thing that changes is the browser that you choose.
Of course, browsers such as Chrome, Edge, Firefox, Opera, etc. they are only able to read PDF.
You cannot do any type of editing. For that if you need a specialized tool. Adobe Reader also does not let you edit anything, it only serves to see, the editor is a payment program.
This format is the standard format for printing on paper. This is a vital point. It is a format that is designed to reproduce on paper and all the information it contains is necessary and essential for it.
This format is a certified format, that is, when the export process finishes, the file is certified and will work as expected.
No surprises If there is a problem in the execution of the format, it will notify us so that we correct the corresponding errors.
On the other hand, and this is the most important difference in relation to the 'High quality printing' format, it eliminates all the extra elements that are left over and are not necessary for reproduction. Let's give examples:
In the 'High quality printing' format, everything that the document contains is included in the file.
If we have placed an image at 300 px resolution and we have reduced it by 50% we have an image at 600px resolution, 300 px extra.
If we have cut the image with a 'paste inside', the whole image - even if only a part is displayed - will be exported next to the PDF.
With this format this does not happen. The export will eliminate the unnecessary information, reduce the images with extra resolution and eliminate everything that is not necessary for the reproduction in a printing press, such as metadata, links, video, sound ...
Also, if you want, you can match all the maps of color to leave the whole document unified.
That is the reason why sometimes a document in 'High Quality' occupies many megabytes and yet.
.PDFx quality occupies very little. What's left over has been eliminated.
When we export from Illustrator or InDesign we have .PDFx-1, .x-3, .x-4. Their differences are minimal, but they can be fundamental.
The x-1 is the basic format for grayscale paper, CMYK and direct inks. That is, the information that will be transferred will be that and only that.
x-3 is designed for hybrid formats. Therefore, it includes color information in both CMYK and RGB, since sometimes we are interested in keeping the original info in RGB in case that same document will be displayed online or distributed digitally.
x-4 allows all the above and also transparencies and layers of information.
There is also a new x-5 in which you can use external images that augurs that will be composed with images linked to the network.
