## What is PDF Compressor?

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 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%.

• Really attractive, super easy to use interface.

### 4/5 — Quirky UI,  but it works

*2018-01-15, version 2.2*

You need to read the help file carefully, but it works as advertised. Reduced a 13MB PDF to 1.5MB with good results.

### 1/5 — I really need a refund

*2018-01-14, version 2.2*

I’ve never requested a refund on an app, but this app is useless. Not user friendly, and I cannot get it to work. Waste of money!

### 3/5 — Doesn’t work with links

*2017-12-08, version 2.2*

It does work as described.  However, it doesn’t read the links I had in my PDF. I was really hoping it would shrink the PDF without stripping out the links embedded within it. 

Add link support and this is easily 5 stars

### 5/5 — Great!

*2017-07-08, version 2.2*

This app package(merger, splitter, and compressor) saves me so much time and works great!

### 1/5 — RUBBISH

*2017-01-09*

Total waist of £4 yes it reduces the size, but with such a quality loss you can't see what any picture is
Meant to be.

### 5/5 — Yea, it worked!

*2015-08-26, version 2.1*

I originally wrote a negative review because it made the file bigger. I am happy to say that I have now used it to make a pdf much smaller (w/ adjustments to quality). Hopefully the last time was just a fluke. I am now very glad I have the app.

### 5/5 — Works

*2014-10-28, version 1.1*

Very useful for sending files by email.

### 2/5 — Need bugs fix,

Need bugs fix, hard to use with ipad, very confusing app, very slow etc.

### 1/5 — Review

*2014-08-15, version 1.1*

*2014-05-18, version 1.1*
