Power PDF Compressor

Power PDF Compressor is a fast and approachable Windows utility that can reduce the size of PDF documents in order to free up space on the hard disk. It does not come equipped with complex features or configuration settings, so it can be handled by anyone.

Quick setup and simple GUI

Setting up the program takes minimal time and effort. Its interface is user-friendly, based on a regular window with an intuitive layout, where you can point out the source PDF using the file browser only, since the drag-and-drop method is not supported.

Set compression settings

The image compression mode can be selected between low, normal and maximum, while the output image quality can be picked between JPEG and JPEG 2000. In addition, you can ask the tool to compress graycale photos too, choose the saving directory (same as the source or different), as well as set the JPEG quality level separately for color and grayscale pictures.
In addition, you can resample the images by specifying the maximum width and interpolation method, convert JPEG to JPEG 2000, as well as convert Flate Decode Filter to JPEG or JPEG 2000 or skip it altogether.

Evaluation and conclusion

CPU and RAM consumption throughout our evaluation, and the tool did not hang, crash or pop up error messages. It carries out resizing jobs rapidly and has a good response time. To sum it up, Power PDF Compressor offers an effective solution to resizing PDFs, backed by numerous configuration settings. However, its price is a little high.
