Is It Damaging for Quality to Compress a PDF?

Do you want to send your PDF via email? Then you need to make your file smaller by compressing it. Do such manipulations impact the quality of your PDF? Let's see.

Compressing the PDF file means that some unnecessary data is removed from it. Usually, it is data from the pictures included in the PDF.

If you compress your PDF not strongly, then the difference will not be visible at all. The text remains readable and high-quality. The text cannot be spoiled since it is made of basic shapes and lines.

The higher the level of compression is, the worse the image will be. Your pictures can get blurred. Details of the photos can disappear. Also, colors can become less vivid. In general, the higher the level of compression is, the worse the quality.

You can select the level of compression for your PDF in almost any PDF tool. There are three options usually – low, medium, and high.

To sum up, compression can harm the quality of your PDF but only when done excessively. Light compression is harmless.
