    How can I compress any PDF to 200 KB?
    Community Answer
    You can't. A PDF can only be compressed so far. If you have some file size limit, your best alternative is to upload it to a cloud service.

  • Question
    Of these options, which are lossless and which are lossy? (ie. which is best for text pdfs)?
    Neelam Jain
    Community Answer
    The text in PDF is mostly gzip compressed. Hence, there will not be any significant gain by any compression technique. The compression level is dependent on the size/resolution of images in PDF. This is a lossy compression where images inside PDF are compressed. I have generally used miniimagesvideos.com/pdf for high compression ratio. There could be some gain in PDF due to removal of some of the unwanted objects in PDF. However, this will not be significant.
