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

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 PDFs 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 theyll not only get there faster but be quicker to open. Dont 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%.

Latest reviews of PDF Compressor app for iPhone and iPad

First impressions are very good
Ive just downloaded this app and was a little worried since it had no reviews yet. The initial welcome message after downloading didnt give a good impression because it has a lot of language errors. However, after 10 minutes with the program Im really impressed and would recommend it. It does exactly what I want, which is to reduce the size of a handwritten PDF made in the Notability App to something small enough to e-mail. (This is a big fault with Notability I find: excessive file size). I wanted to use my phone to handwrite letters in Notability, then e-mail them directly to my family from my phone or tablet without needing a computer to reduce the PDF size first. This app has solved this problem for me. This app is very intuitive and I figured out how to use it without reading the instructions, which is always the best test. I like the way that I can easily play with the DPI setting to find a balance between file size and legibility. After a few experiments I found that the apps default 144 DPI was perfect and made my files about 1/3 the original size with no loss of legibility. Its also great being able to see original and modified file sizes on your phone, something Apple seems to hate showing. Overall, it does just what I wanted. Your needs might be different from mine, but its solved a problem for me. Id recommend this app.
Need bugs fix,
Need bugs fix, hard to use with ipad, very confusing app, very slow etc.
Not useful
This program simply decreases sise of pdf file by aggregation (merging) pixels. As a result text pdf file becomes unreadable or readable but with very poor quality. I hoped that this program can decrease pdf file and save its quality with acceptable level. But it can not.
Works
It brought my file size down from 18mb to 3 mb without any noticeable difference to quality. But for this you have to be willing to bring the resolution down to 72dpi (screen resolution) and reduce image quality. I could have compressed further but 3mb is fine for email. I cannot comment on how compression would effect print quality. I am very happy I ventured out and bought this app. There were no reviews so I guess I got lucky.
I hope the first review wasnt fake
Cuz Im taking the plunge and downloading now. If I dont edit this review, it means it worked! However, if it doesnt I shall return and cuss away.
