OverviewPDF is a format which stores documents that can include text with distinct fonts and images. The text that is present in it is of static or fixed format which is just like an image and it remains exactly the same even if we open this file using other programs, hardware and different operating systems. That is why it is recommended to convert the file into this format before printing or transferring, so, that the arrangement of the lines remains the same. Thereby, the output that is generated is always a printer-ready. These files are editable and can be amended using various editors. Several files can also be merged and compressed online. It does not only support Adobe Acrobat Reader but also other similar programs. These files can be sent, saved and viewed easily using phones, computers or tablets.
