Now if we discuss the types of file format MacBook supports, then we came to know that MacBook can support almost every kind of file format. but sometimes due to the faulty handling of the users and because of some technical faults file formats like that of pdf do not open in the MacBook. But first, we should know what is a file format.

File format:

When you working on the computer or any other device, whether you are performing data searching based work or maybe downloading images or audio and video files for all such activities you excess or store digital or analog data. For the excessing of digital data and its storage, the computer system must do the encoding. These encodings are done in the form of a file and stored with the specific names on your computer.


A file is either a homogenous or a heterogeneous combination of different types of data that appears solely to the user. For such kind of data encoding, we need a way by which we can easily access files and store data for later use. This is where the file format plays its role. A file format can be defined as, the standard mean or way of encoding data that stores in the computer memory as a file. The file stored can be of different types like it may be plain text, images, audio files, video clips or it can be multimedia files too. For encoding, each type of data separate file formatting options has been built that allow you to store data more efficiently.

File formatting is very crucial as it is important for the long-term storage of data without being changed. We all are well known for the fact that computer systems manipulate based on binary systems. The binary system is a system that is composed of zeros and ones. The binary system is the language that is used by the computer. And each letter or the symbol which you see on your computer’s keyboard has a specific sequence.

The same is in the case for images. Images are specified based on pixels. Pixels are the successive series of dots that are specified for each type of image. So, is it possible for a human brain to learn all such sequences and then work on the computer? The answer is clearly NO! to solve all such problems a system of file formatting is designed which can encode all such successive series either of binary system or pixel system. File formatting can encode and store data in a human-readable comprehensible system.

File formatting puts a milestone in the field of technology that allows you to encode and encrypt the difficult sequence of data and store it for a long-term period as well. Many different types of file formats are available that supports different type of data. But there are file formats present that can support multiple types of data as well.

Types of file formats:

There are multiple types of file formats that support the encoding and storage of many different types of data. These file formats are designed to provide encryption of multiple types of media. There are hundreds of file formats that support millions of databases but some of them are discussed as under:


  • JPEG: JPEG stands for joint photographic expert group. It is one of the most famous and common types of file format that is being adopted by the digital camera and the world wide web for image formatting. it is a light weighted file format that stores and encodes images in the least possible size. Moreover, it also compresses the size of the images without comprising its quality as well.
  • MP4: MP4 stands for moving pictures experts’ group. This format supports audio and video file. The advanced attribute of MP4 is that it can also support the subtitles which are being displayed in the video clips as well. furthermore, you don’t need any additional program to open up MP4 media files as almost every electrical gadget supports MP4 files. It is light-weighted and compresses files too which also helps in decreasing the file size as well.
  • PDF: portable document format is an abbreviation of PDF. It was developed in 1992 by adobe. The main aim of building this format was to design a file format that can encode plain text along with images, audio, and video files too. It is due to the fruitful attribute of the PDF file format we can create long documents and can share them with others without being scared that our data can be lost during the transfer. PDF does not do data or information discrimination. It displays the file in the same manner whether you are using IOS, Android, or windows to view PDF files. It keeps the formatting the same regardless of what device or gadget it is viewed or display on. Moreover, PDF format is supported by many different kinds of software like Microsoft office word has a built-in option of export to format the document in the PDF form. Moreover, pages of IOS, adobe acrobat, and google docs also support the PDF format.PDF format also supports metadata as well.

Along with the above-mentioned types of document or formats there are other file formats like TIFF, GIF, MP3, DOC, ZIP, WAV, and Ogg, etc. that support different types of databases. This helps in faster and specific encoding that allows finer and better storage.

File formats that mac supports:

Similarly, if we see the memory and storage, it has increased storage than any other ordinary laptop. Some pre-installed applications and processors have also made part of the MacBook, which makes the MacBook more efficient. Like that of other features, MacBook can also support different file formats as well either solely or by a third party like that of adobe acrobat. These file formats help in better storage and the user experience finer working too.

Some of the file formats that MacBook supports are:
