PDF Compressor makes it possible for anyone to reduce your PDF documents size, especially useful for those PDF files with many big scan graphics and photos.

PDF Compressor offers easy ways to compress your large PDF files on Mac to a perfect small file size that is still good quality, you can send smaller and faster emails, save your storage space, decrease file upload or download times after reducing file size of PDF documents.

Portable Document Format (PDF) files are the open, standard way to deliver documents electronically. Supported by virtually any platform—Windows, Mac OS, Linux—converted PDF documents, graphics, charts, and forms look exactly as they would if they were printed. At times, it is necessary to compress these files to be able to send them as email attachments or upload them to websites. There are many options for compressing PDF files

> Be Smart for Mobile Phones - Compress that PDF!
With more website visitors using mobile devices, why treat them like second class citizens by including large PDF's on your website, email or app? Use PDF Compressor to shrink the files and make them more friendly for mobile users.

> Emailing PDFs?
Why clog up the inbox of your friends and co-workers? Compress the PDF file before you email it, that way they'll not only get there faster but be quicker to open. Don't forget major mail providers have a file size limit of around 20MB, so compressing PDFs also means that attachments are more likely to arrive.

> Perfect quality!
Reduce your scanned PDF files to 144dpi which is perfect for uploading files to the web and through email on mobile phones.

> Balance between image quality and storage size
PDF Compressor reduces file size by compressing the images within PDF document. It uses JPEG, which is a commonly used method of lossy compression for image. So you can get high quality but small PDF file after compression. For some PDF files, file size can be reduced by 90%.

> Support Mac OS X 10.8 or above.

Customer Reviews

Rather Good


This app is rather good. I use it to convert several pdf files, the compression works well. A file with a size of 10MB could be compressed to 4.4MB. Very professional. Of course we can choose the zip apps to do the same thing, but the effect of compression may not so good. I have a try, the 10MB-sized file is compressed to 8.2MB by using the built-in compression program on my Mac.



there is no recognition of your settings, that is to say, reopen the app and your chosen compression settings will not be there or saved.

The three times I used it, the file was output larger than the input file. Kind of defeats the point, and it was lower quality.
