How to Compress the Size of a Acrobat File
For most users PDF files are incredibly useful. They retain all the users' details and cannot be modified by other users unless express permission is given. PDF file formats were also very detailed in their look and presentation. Large corporate presentations, intricate files and even charts could be easily placed in the files and sent to clients without the need for hard copy backups. Each PDF file could follow the formatting that was placed in the electronic copy to the tee, recreating images, charts and colors perfectly. But this same feature of carrying detailed images and text made PDF files really large and bulky. Sending the files over the internet in the form of attachments became difficult and end users complained about download time required for a single PDF file. It became extremely necessary for users to know how to compress the size of a acrobat file without losing the data and image quality in the file.
Reducing PDF File Sizes
The newer versions of PDF authoring software now have intricate layers of compression algorithms that automatically compress PDF files when you close them. But other than that you can also ensure that you're newly created PDF file is made as small as possible by following a few simple tricks. For example, you can start by unembedding fonts that are present on your PDF file. Almost every user will already have a range of fonts saved on their computer systems so it's totally unnecessary to send the same information to them again. Deleting the unnecessary fonts can reduce as much as 40K of space on your PDF files per font. This turns out to be a considerable space reduction as every PDF file carries at least a minimum of ten fonts! There is no need to worry as file quality is not affected. Even if the end user does not have the fonts embedded on his system, the software displays the file in any font that is convenient.
Compression Algorithms and Their Details
You can also delete unnecessary information carried by rote in all PDF files by using a command to remove such information. You can also remove layers in form fields with a single command, thereby lowering the bulk of the PDF. Embedded and unused fonts can be removed, retaining only those glyphs that are actually used in the file. This can be even further improved by manually using less number of glyphs at the data creation stage itself. Other compression measures include pre-compressing images before embedding in PDF, which may include changing images to greyscale, discarding color information, converting images to vector graphics and other methods.
