Why Compress PDF Files for Free Online

So often we encounter problems when we need to upload documents like presentations to the web, only to find that they are too large and not web-friendly at all. Uploading and transferring large files is a cumbersome process and eats up a lot of unnecessary bandwidth. Documents that create a variety of images, styles, fonts, and any audio and video formats end up as large files. However, the Portable Document Format or PDF as we know it, is a standard format that can be created in any application and viewed under any operating system. When we convert a large document to PDF the file size increases even further. In order to make a PDF more web-friendly you need to reduce the file size. File size can be reduced with a PDF compressor. Files can be reduced to half their size with this compression tool. You can also compress PDF files for free online.

The Techniques to Compress PDF Files for Free Online

PDF compressors use various techniques that are based on algorithms to compress a PDF. Flate, Zip, JPEG and Run Length (RLE) are the common techniques used depending on the layout of the file. This tool adjusts all objects such as videos and images to reduce file space. The programs scan all metadata and text to remove unwanted objects before compressing it. The resolution of images and videos is reduced and font sizes are decreased prior to compression. All colors and background styles applied to the original document are also adjusted. You can download PDF compressors or even compress PDF files for free online. These tools can help to free up valuable disk space and increase upload and download speeds since most email providers restrict attachments between 5 & 15 MB.

Advantages and Limitations of Compress PDF Files for Free Online

Free online PDF compressors allow you to upload documents to be compressed. The compression process begins once the file is uploaded, resulting in a new compressed PDF. The only drawback of online compression is that only once document can be compressed at a time. Some developers allow you to download an evaluation copy to test the program prior to uploading a file for compression. If you are a small user these programs to compress PDF files for free online are ideal.
