Best Programs to Compress PDF without Losing Quality

PDF files can be quite busy if their content is quite wide, and especially if it includes images. For this reason many users are looking for a way to compress PDF, as they may have problems with the size to send their files through services such as Gmail.

Many services limit the storage or sending size of our files and that is why, so many users look for ways to reduce this weight without losing the highest possible quality, in the event that they contain images.

And this can be easily achieved with the programs shown below.

This list does not keep any order, all those mentioned below contain characteristics that differ from the others, and it is the user who decides which one to use.

Jsoft PDF Reducer

This tool is easy to use and also complete, since it not only allows us to compress and reduce the size of our PDF files, but also allows us to combine several files into one.

Although it allows us to join them, in the case of wanting to separate a PDF document into two, it also gives us that function, or that of deleting pages and selecting the one we like or want to have. And while these functions are not available to any viewer, or PDF editor, it includes more options such as adding watermarks, rotating pages or even reorganizing them among many other options.

This program is available in two languages (English and French). We can download it in the link shown below the image.

This PDF reducer is quite advanced, since it incorporates an automatic color detection and performs a design analysis. This is intended to reduce the design considerably and without significant quality losses.

Resample the images to reduce their quality, so that they continue to look just as good. This is because many images that we introduce, incorporate too much unnecessary quality, and that is why it is reduced to a point which still has quality.

The procedure is performed quickly, but this includes the use of higher CPU usage, reducing performance momentarily while the process is running.

This program is not free, but we can access its trial version in the link shown below.
