Why do scanners use PDF as the default file format? [Tip]

This is true of every application that you use to create new documents as when you save a document for the first time the software application will assign its default file format to the newly created file.

The Default File Format: Different Types

Various applications process data with functions like creating new files, modifying existing files, and saving these files in the default file format relevant to that specific application.

Here is a list of the more common applications and the default file format they use to store their data or files.

Application Name and File Format

MS Excel = .XLS

Notepad = .TXT

MS Works Word Processor = .WPS

Comma Separate Values File = .CVS

PowerPoint Presentation = .PPT

MPED-4 Video File = .MP4

Portable Document Format File = .PDF

Microsoft Access Database = .MDB

Active Sever Page File = .ASP

DOS Based Executable File = .EXE

Compressed Zip Archive = .ZIP

The Default File Format of Scanned Documents

Many scanners today offer creation of new scanned files in multiple file formats. Though the default file format is still PDF with these scanners, they give you the option of selecting a different file format before you start your scan.

Conclusion

When you use a scanner to scan your documents, the documents are stored as PDF files by default in the scanner memory. They can be emailed to you so you can then process them to suit whatever purpose you scanned them for.

You may need to modify the document using MS Word or MS Excel or some other word processing or spread sheet software. To achieve this, you can change the default file format of the PDF file by opening it using an application different from Acrobat Reader and saving it in the format required.
