Portable Document Formatted files generally could be compact and could be much smaller than the PostScript files. A lot of people use pdf online compressors for compression. How it is achieved is with a better data structure however it is due to the effective pdf compression algorithms in such a format that is capable of making the size of a file real compact.

The listing of compression algorithms that could be brought into an extensive level usage comprises the following:

1. JPEG– It is a lossy algorithm that is utilized for images.

2. JPEG2000– An updated edition an alternative to JPEG.

3. Flate– For the compression of text and images, this one is used.

4. LZW– This replaces the compressed text and image.

5. RLE– For monochrome images, it is used.

So How is it that you can Compress PDF files?

Given that compression is switched on in Acrobat Distiller then it would at first compress all the images in PostScript file and once more would compress them whilst it is creating a file in this format using pdf creator. In order to check the compression if it had been done in such a file then you could open it by using a text editor that can handle binary data and then search for the ‘Filter’ keyword in the file. Every compression in it carries out its functions in various ways.

For instance, if we talk of the JPEG compression method, which is for images, it means that it is used for color and images in grayscale. The compression could be lossy as well as non-lossy. If the compression is of a higher level, it means that you’d lose more details on the data. Five levels for pdf compress process has been followed by Acrobat Distiller 4 and above editions. Compressing already compressed images would lead to added loss of data. If you distill a file that has JPEG compressed pictures then, Distiller would un-compress and re-compress them as per your settings. This is a disadvantage because there is a risk of losing information if too much compression takes place.

One of the benefits that Internet users have is the easy file-sharing method. It lets you receive or send documents fast in the form of email or by uploading and attaching documents. A lot of Web users are making use of this method today. However, it is always profitable if you know how PDF files can be shrunk and shared. It is one of the popular formats used by people and when the size of the documents is compressed then likely it becomes easy to upload even large files within few minutes.

You could make use of the given guidelines which probably would help you in reducing the size of big files that are to be shared. First of all, comes making use of Adobe Photoshop. You could use it to shrink the pixels by decreasing the resolution. If a document is compressed trash pixel data can be discarded. Also, if you think that quality is not much of a concern then you could probably lower the resolution of graphics or images via photo editing utility. But note that the images are not compressed too much else they’d appear pixelated when printed.

You could save your document as ‘Save As’ instead of ‘Save’. The former one helps you probably to save a small-sized file by overwriting the entire document. By clicking on the ‘Advanced’ menu in this formatted optimizer you could click on the Audit Space Usage. It would help in locating which particular component in the document is needlessly large and could be reduced.

Compressing the PDF files using Discard Objects

Another means to adjust the size of a document is by clicking on the ‘Discard Objects‘ menu and then get rid of the items that are not needed. It as well could be said that you could select unknown options to shrink the size of the file. It is wise to save the optimized document with a new name on the computer system so that you can keep the original document as it is without making any changes, else you could lose it.

We all know that the Internet has proved to be a boon to mankind and when it comes to sharing information with others then this remains the topmost mode. It lets you receive or send files at the highest speed whereby you just need uploading or downloading documents that are needed. Since it is a very comfortable and time-saving process a major fraction of the populace makes use of this kind of data sharing technique.

The usage is being restricted to the documents which are in PDF format. These files are easy to compress, and due to compression they enable to consume less space and a person gets to open the files at a really fast pace. The respective format helps in uploading large files at a very fast pace without any delay or buffering.

Compressing PDF file using Adobe Photoshop

 You could make use of Adobe Photoshop which would show the unneeded pixel content which you could get rid of. With photo editing tool you could lower the image resolution which would take the least space to fit into a file in case there are images in the document and you could compromise over the picture quality. However, this process has to be done cautiously otherwise the graphics might look too pixelated when they are printed on a paper. You could save the document by selecting the option ‘Save As’ as it would overwrite the file that would probably now take less space if reducing the resolution is something you feel uncomfortable with.

Compressing the PDF files using PDF compressor

There is generally a menu bar named ‘Advanced option’ in the optimizer. The pdf compressor helps in identifying that very particular component in the file which has unnecessarily consumed a lot of space or is large and then after the identification process is completed you could remove those components. At times fonts do take up a good amount of space given they are large so you could reduce it. To discard some needless objects in the document, select the ‘Discard Objects’ menu and delete items you do not require.
