Major Differences Between PDFs and JPEGs:

Adobe Systems created and developed the PDF or Portal Document File format in 1992.

The JPEG or Joint Photographics Expert Groups format was released in 1992 by a group named Joint Photographics Expert Groups. 


PDF files are used for storing and sharing text-based documents, images, video files, 3D object designs, digital signatures, etc. It is mostly used for sharing documents and information. 

The JPEG format is used extensively for storing and sharing still images, webpage visuals, etc. 

Size of Images:

As mentioned earlier, PDF files are also used to store and share pictures. In a PDF file, the standard size of every image is preserved. Thus, no changes occur in terms of the size of the images included. 

Exclusively used as an image format, the JPEG format incorporates lossy compression to reduce the size of the digital image. Hence, the format compresses images to save storage space.

Quality of Images:

Since no type of compression occurs, images present in PDF files remain intact, resulting in high image quality. 

The JPEG format uses lossy compression, which leads to the deterioration of the image’s quality. Hence, JPEG images feature a comparatively lower image quality than PDF files.


The PDF format is preferred by the majority of the masses when it comes to printing, mainly because it retains the quality of the content present inside the file. 

The JPEG format is neither suitable nor preferred when it comes to printing. This is because the quality of the JPEG images is significantly lower due to compression. 

PDF and JPEG are immensely useful file formats, and each has its strengths and weaknesses. If you are wondering how to convert multiple JPEG files into a single PDF file or vice versa, refer to the aforementioned methods to get the job done conveniently.
