PDF files that contain many images are really heavy and take up quite a lot of space on your hard drive. For this reason, from Neoteo we present the five free tools to reduce the size of PDF files. We will talk about applications that reduce the size of files by up to 60 percent, so you will gain a lot of space on your computer and can send them via email without complications.
PDFCompress!
We will start with PDFCompress!, one of the best online services to upload and compress PDF files. You can upload PDF files (up to 200 MB) from Dropbox, Google Drive, and your computer, and then begin the size reduction process. PDFCompress! works very well in all web browsers, but in Google Chrome it lets you download both the original and the reduced file.
CompressPDF by smallpdf
If you are looking for a simpler tool that leaves no traces of your files on its servers, smallpdf is the utility you are looking for. Once you upload the PDF (up to 56 MB) and reduce the file size, the platform will automatically delete the documents (after 2 hours of being hosted). CompressPDF by smallpdf is a free web application that works perfectly in all web browsers.
QPDF
QPDF is an application with which you can create web-optimized versions of your PDF files using the linearize. The tool also allows you to create previews of your PDFs to upload to the internet and use a PDF file unlocker. QPDF is a free application available for Windows and Linux operating systems.
ImageMagick
We continue with ImageMagick, a tool for working with graphic formats. But the platform allows us to greatly reduce the size of PDF files (it works together with ghostscript). From Neoteo we recommend this utility for advanced users, since improper use of its commands can activate other application services that will affect your hard drive. ImageMagick is a free application available for Windows, Mac OS X, Linux, and iOS devices.
Neevia Online PDFcompress
We will finish with a bang with Neevia Online PDFcompress, an online application that lets you compress PDF files with different options (high, low, maximum, and medium). This way you can select the type of image quality reduction you need. You can also remove bookmarks, annotations, select file compatibility, and manipulate color compression. Neevia Online PDFcompress is a free web application that works in all web browsers.
We hope that the mentioned applications help you reduce the size of your PDF files. Also remember that these tools for reducing PDF files are not of great help in files that lack images and only contain text.
