PDF Studio

I’ve been using PDF Studio since version 6.62. Back then, years ago, it was IMHO the best of the many PDF editors on the market (including Acrobat-by a mile!), although it did have a few head- scratching shortcomings, including the absence of an undo function (!?) and occasional crashes when working with multiple PDF files simultaneously. These and other glitches seem to have been fully corrected, however, by a series of updates through version 12 and, most recently, to PDF Studio 2018. In addition, new functionalities and design improvements, including a totally revised navigation ribbon, have made working with the software faster and more intuitive.
My main use of PDF Studio over the years has been in studying, annotating and playing classical piano music from pdf keyboard manuscripts. The software lets me:

• remove and modify manuscripts’ piano fingerings to suit my hand size and interpretation of the music,

• highlight manuscript areas that I need to focus on by overlaying them with highly transparent rectangles of pale color,

• attach audio files to the pdf manuscripts of the music I am playing so I can hear how various performers interpret the music while I am studying and playing it,

• insert bookmarks into the manuscripts to enable navigation through compositions’ sections,

• add notes directly on pdf manuscripts about my interpretation and performance of the music,

• use PDF Studio’s many other powerful features to enhance my piano studies and playing.

For years I’ve been content to use my old version 6.62, which still remains among the best PDF editors available. But at this point it’s clear to me that PDF Studio 2018 is far and away the most flexible and powerful tool for building highly creative PDF editing applications that can enhance whatever kinds of computer work one undertakes.

I was looking for a good tool to view/ edit and markup PDF's on my MacBook. This product does everything that I was looking for, the measurement tool is easy to calibrate and allows me to quickly review drawings and add comments.

I would recommend this and indeed already have to some workmates.

I use it for markups of drawings and the tools are more than sufficient.

Yes there are watermarks on the free trial version but then it is a trial so its to be expected.

Out of the various products I have tried on the Mac this is the best one and most in line with what I used to use on my PC.

I was happy with the editing abilities since version 8. Running on Ubuntu Mate 16.10 I print plans very often to wide plotters and often need to print several small detail sheets per page. Before version 11 I had a lot of problems printing, to the point that I couldn't print a standard 8.5 x 11 on my HP Officejet 8600 Pro without major scaling issues. To the point that I had to use adobe reader 9 to print any PDFs. Version 11 has been a much-needed update for the Linux community. Great job adding requested features.

Also, this software isn't cheap, but It is an excellent set of tools for anyone running Linux in a business that requires lots of printing. I've tried Foxit Reader, Master PDF editor, qpdfview (which I use as default viewer because of its excellent speed with large documents) and this really is the only product that is complete, actively developed, and offers much better than expected customer support.

On windows I use PDF-x-Change Pro and recommend it to anyone using windows, Although PDF Studio may now be worthy competition.

Qoppa PDF Studio is a best pdf editor suite for Linux. I tried few other opensource and paid softwares , all are good for reading pdf files but PDF studio stands out as best pdf editor for linux. The Premier pdf apps on windows and mac are not available for Linux platform. Thanks to Qoppa Team for supporting Linux Platform considering the needs of users. The User interface looks similar to most windows apps and it as robust performance in reading and editing mode.
The OCR is best among all other apps for linux.

I stumbled across this software searching the PDF universe for a macOS PDF reader and editor. Spending fruitless hours over the months searching & subscribing and seeing the regulars, Wondershare, ABBYY, Adobe etc

In all of the regulars, these interfaces / GUI does not compare to Qoppa for ease of use, look & feel and intuitiveness. I am really excited to use this software because it looks APPLE and it just works.

I like the ease of how you can pan drawings without slowdown of app and with other software, if you wanted to convert images to PDF or vice versa, you need to go online, login, pay etc. I can even see layers and turn them on & off - an advantage to reduce the clutter in PDF drawings.

With PDFstudio its a click of a button in the app and its done.

This simplicity improves my workflow and reduces stress levels due to tight timelines and in todays world of 1 click, you just want this to work first time and not relearn workarounds etc.

Thumbs up team.
