2. Why the compressed PDF file is still big or larger?
Text PDFLots of text PDF files have been compressed once created. So the file size could not be reduced anymore.
Scanned PDFFirst please check if your PDF files are scanned PDF or not. Scanned PDF documents are made from images so that the program can compress it. If the PDF files are not scanned PDF, the compressor will not work properly and make files bigger than before.
Another reason may be the PDF file has been compressed already. Once the PDF file has been compressed, you cannot compress it twice.
3. Why the compressed PDF Pages are Blurring (Scanned PDF)?
Please check the Compress Quality and DPI value. If these two values are too low, the compressed PDF file could not keep the good quality. Try to turn the Compress Quality higher than 75% and set the DPI to 120.
