PDF Compressor Online
There are thousands of online PDF compressor programs that can come to the notice of users. But compressing PDF files is necessary if you want to attach them to emails and send them over the internet to other users and clients for review. If the file is too large and is taking too much time to attach to emails and to download; you have to carry out a PDF compressor process that is freely available online.
PDF Compressor Online Sites
One good way to find out whether your file needs to be compressed is by checking your file and then carrying out a file audit. You can carry out that by using the AUDIT SPACE USAGE button in various PDF authoring software. The resulting data will show you where the file is using so much space. You can locate the exact area where your file is occupying space and then reduce those. You can use PDF compressor online programs that will do the same process by detecting heavy areas and then decreasing them mechanically. Before you actually submit your files to an anonymous PDF compressor online site, check the sites thoroughly to find out how the site works. Most sites work on a combination of compression algorithms that work together to reduce file size. For example, most compression algorithms like JPEG, JPEG 2000, FLATE and TIFF work on lossy or lossless compression. Lossy may cause a loss of valuable data in images while lossless is safer but with much lesser compression. Find out how much compression a PDF compressor online site can offer you by first uploading a test file for review. Do not upload files unless you have checked out the reputation of PDF compressor online sites.

Check to find out whether the PDF compressor online sites offer mixed raster content compression that works best to compress PDF files which have images and content. Mixed compression can provide about 300:1 compression rates while still retaining their image and text quality. If the site does not have layered compression and you have incredibly detailed PDF files, please use paid or downloaded software that works better than free software.
