Compress PDF

PDFCap's PDF compressor lets you control the trade-off. A moderate setting cuts file size noticeably while keeping text and images looking clean. For mostly-text documents, you'll barely see a quality difference even at stronger compression levels.

It depends on what's in the file. How much you can reduce PDF size varies quite a bit. An image-heavy document can shrink by 70% or more, while a text-heavy one compresses less, since plain text is already fairly compact.

High-resolution images are usually the culprit, along with embedded fonts and unoptimized scanned pages. Using PDFCap to reduce PDF file size strips out unnecessary data and compresses those elements, leaving you with a much smaller file that's much easier to share or attach to an email.
