Compress PDF has the capability to minimize file size of PDF documents, especially useful for those PDF files with many graphics and photos.
You can send smaller and faster emails, save your storage space, decrease file upload or download times after reducing file size of PDF documents.

• Extremely simple
Simply drag and drop the PDF files into the app to get started, compression will begin immediately. You can easily send PDF as attachment directly after compression.

• Rich choices of compression options:
It provides 10 preset options to meet your different demands. You can choose from lossy image quality to minimal file size as you wish.

• Balance between image quality and storage size
Compress PDF 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%.

The app may not work for PDF files that was compressed before, your understanding will be appreciated. If you have any questions, please contact before leaving a negative reviews, thanks for your support.

Some problems

With some scanned pages the compression is too aggressive and documents become illegible even after playing with all the different compressions options.

Effective and Wallet-Friendly

User-friendly and useful for the price. However, compression/file size reduction was limited on some files. I used this application to shrink down PDF sizes to upload/email. For $0.99 it’s definitely worth trying.

Doesn’t work for some of my PDFs!

For some of my files; I get the following message, even after trying all options (including the 50 DPI one)
“Could not reduce file size”

Works for most of my other files. Ah well.
