To have tools to compress PDF’s online, has become a necessity for all of us who work every day with documents in digital format. And, despite the innumerable advantages of this type of files, there are times when their weight determines us when using them.
Therefore, and although we already know other tools to edit PDF‘s for free, some of them do not have the option to compress them to make them more manageable and be able to store or share them with other users online.
And is that the format “Portable Document Format” have earned the reputation (deservedly) of being safe and comfortable to send various jobs by email.
However, these files are sometimes very heavy for some computers. Therefore, tools capable of compressing PDF were invented, such as those that I am going to show you and explain in detail in this article.
Can I compress PDF’s myself to reduce their weight and visualize them correctly?
To facilitate this work, I will tell you that it is possible to compress PDF without losing quality, thanks to various programs. In this way, you can see the files that you still save on your device in this format without losing a bit of content and preserving the memory and the proper functioning of the system.
However, we must not forget what are the possible situations in which you might have to go to one of these online tools:
Why May We Need To Compress a PDF?
First, if you review the characteristics of a document of these characteristics carefully, you will find that each file of this nature is divided into several sections that, at most, reach 1 MB of memory.
Its average weight is approximately between 200 KB and 400 KB.
However, the average weight that I just indicated is for a simple file, that is, a file with only one page and that is not generated from printed documents or images.
On the other hand, when it is a scanned file or an image , the thing changes completely, since it gradually increases in weight on the device where it is housed and becomes complicated to read.
What are the consequences of trying to view a file that is too heavy?
Because it occupies a very significant space in the device, it causes that when it reaches its storage limit, the file slows down and even presents certain malfunctions.
When this type of thing happens, it is when it becomes indispensable to be able to compress and reduce the weight of the PDF , without losing its content or the images that contain it.
What Are The Main Advantages Of Using Files in PDF format?
Reducing the storage weight of this type of digital documents has multiple benefits that, although I have already briefly mentioned some of them, now I will show you all more carefully:
► Friendly For Users And Operating Systems
Today, everyone knows this digital format, so no one is surprised to see such a document.
This makes them easy and quick to create. In this way, if for example you are late for work and need to deliver a document of this type, you can create it quickly, preserving the style of the original work.
► They Are Universal Archives
These are, in most cases, compatible with all types of devices and operating systems, such as Windows or Mac. By this I mean that they can be viewed from any computer or device, regardless of the type of software they use or the brand they are.
► They Are Safe Against Virus Threats
As I mentioned earlier, these documents stand out for being safe, since you can encrypt the data contained in the file and even add watermarks. In this way, the information cannot be easily replicated or edited without the author’s permission.
► Can Be Compressed
Finally, I can verify that its best advantage is the capacity it has to be compressed, since, in the case of occupying a large space in the system, it can be reduced, preserving the information it originally contains.
What Are The Advantages Of Being Able To Compress a PDF?
Following the advantage that I have just mentioned, you will deduce that there are many benefits that you can find when you discover how to compress a PDF , among which the following stand out:
1. The Speed
The operation to be able to compress a PDF does not require too much time, since if the file in this format is large, the system will take at most an hour to compress it.
The time varies depending on the content and the amount of sheets that are contained in the file, since it is an intense operation, which requires a lot of energy, but is usually fast and effective.
2. It Means a Great Saving of Space
Whether your device is a mobile phone, a tablet or something more complex like a personal computer, the result is the same: file compression increases the space available on your device.
The compression will be more effective if you have several files that you want to compress into one, eliminating the originals, as long as you only need the information contained in them and not the entire format itself. In this way, the space occupied on the device that was required by the complexity of the file will be completely free and available.
3. Facilitate downloads and shipments
In the same way, they become very comfortable to be able to send them by email for later download. That is, because the file now has a lower weight, it will be downloaded more quickly and efficiently and it will even be less “cumbersome” to send it.
However, it should be borne in mind that if the compression is of the type of joining several files into one, then the final file will have a name similar to xxx.zip (or something ending in ZIP).
And today, some devices still do not accept this suffix, because they used to contain many computer viruses.
4. Provides security and privacy
Due to the high security demand that some files have presented in recent years, file compression programs have developed various encryption systems that work to protect files at the highest level.
5. Quite powerful encryption
It should be noted that encryption is one of the most powerful protection systems, because it is an extremely long code and is not usually easily deciphered.
Therefore, it can only be seen if you enter the password. It is important that you remember her (or write it down in a safe place) because otherwise, you will completely lose the file.
After reviewing these interesting advantages of compressing PDF’s together, I would like to show you some platforms to carry out this task:
