Quality vs. Size Trade-off When Compressing a PDF

When compressing a PDF, there is a trade-off between the content's quality and the File's size. As the file size is reduced, the quality of the content can also be reduced.

Reducing Image Resolution

One way to compress a PDF is by reducing the resolution of images. Lowering the resolution of images will decrease the file size, but it will also make the images appear less sharp and clear.

Additionally, if the PDF contains multiple images, it is possible to compress them using lossy or lossless compression techniques. Lossy compression techniques will reduce the file size more than lossless techniques, but the quality of the images will also be reduced more.

Removing Embedded Fonts

Another way to compress a PDF is by removing embedded fonts. Embedded fonts increase the file size of a PDF, but they also ensure that the text in the PDF will look the same on any device. Removing embedded fonts will reduce the PDF file size, but it can also change how the text looks on different devices.

Removing Multimedia Content

Removing embedded multimedia content, such as videos or audio, is possible. It's important to note that the overall quality of the PDF will depend on which of these methods are used and to what extent. It's a trade-off between the final file size and the quality of the final PDF.

It's also possible to use a combination of these methods to find the right balance between file size and quality. It's best to experiment with different settings and compare the results to find the best balance for your specific use case.
