The PDF file format is losing its spark, but many companies and websites still rely on PDF files to provide users with information. For example, the business & purchase receipts, invoices, banking receipts, etc., were all sent to use in a PDF file.

PDF, or Portable Document Format, is a very popular file format. It’s mainly used to present documents, including text formatting and images. Compared to other similar file formats, PDF is more secure as it can be edited only through a dedicated third-party app.

If you run an online business and deal with PDF files, you would have felt the need for a PDF Compressor app. PDF Compressor apps can help you reduce the file size of a PDF without affecting its quality. Many PDF Compressor apps available for Android can compress your PDF Files in no time.
