The PDF is one popular file type to exchange different types of information. Mostly eBooks, article pages or simply a collection of images. To open and view PDF files you need of course a PDF viewer.
There are many of them, but I picked out the ones which I think are the most popular and useful.
The following PDF readers/viewer are being compared:
The icons of Adobe Reader, Foxit Reader and Nitro PDF Reader all look very nice. Nitro PDF Reader uses the ribbon toolbar with nice big icons and additionally describing titles to them. The icons of PDF-XChange Viewer remind me of Windows XP times.
While the icons of SumatraPDF and the interface itself look overall very minimal. And it only shows the most basic functions like print, page number, page navigation, page view mode, zoom and search. There are tabs used for the opened PDF files by Foxit Reader, PDF-XChange Viewer and Nitro PDF Reader. PDF-XChange Viewer even can give you a thumbnail overview of your opened PDF files.
They all have different page view modes like only one page at once or two beside each other like you know from real books. A full screen view is also supported by all of them. This is useful if you want to concentrate on the pages only.
All but SumatraPDF have a thumbnail sidebar of the pages for a comfortable overview of the document. You can jump to page numbers and navigate with the forward and backward Buttons in all of the apps.
And all but Adobe Reader and Nitro PDF offer bookmarks. So you can place bookmarks for any page and jump right back to your page the next time you open the PDF file. SumatraPDF has a boomarks function in its menu but I am not able use it because it is disabled for some reason.
Web Browser Integration
All of the readers integrate into your web browser. This means if you open a weblink to a PDF file it opens in you browser window instead of opening in an extra window.
Browsers supported include Internet Explorer, Firefox, Opera and Chrome. Tough chrome has its own PDF viewer integrated which won’t be replaced. SumatraPDF does not install into Internet Explorer.
None of the apps seem to have a noticeable faster or slower start-up. But there are big differences in their RAM usage. SumatraPDF uses a lot less RAM than the others (about 1 MB – no file opened). While the Nitro PDF Reader uses the most (about 51 MB – no file opened). Adobe Reader, Foxit Reader and PDF-XChange Viewer use about the same amount of resources (12 MB, 16 MB, 11 MB), which is absolutely acceptable.
Only SumatraPDF and PDF-XChange Viewer offer a portable version besides the regular installer. Simply download, extract the archive and run the app. You can copy it to your USB stick and run it on other Windows machines without installation.
Exporting PDF To Image
Some times you need the contents of a PDF file as image file. All but SumatraPDF and Nitro PDF Reader support this. They let you take screenshots of your area of choice. PDF-XChange Viewer even lets you export whole pages to image files.
A very handy feature is the note feature which gives you the possibility to place notes directly on the pages of PDF files. This can be helpful if you need to remember something for later or to make notes for another person. Adobe Reader offers you to place basic notes as overlaying boxes in PDF files and highlight text areas. With Foxit Reader and PDF-XChange Viewer you can even draw lines and arrows. There are no note features in SumatraPDF.
Text To Speech
Adobe Reader and Foxit Reader are the only which offer text to speech features. This can be very handy if you want to do something else while listening to the voice reading for you. Tough the voice sounds very robotic.
Some of the apps have some nice little extra features. Nitro PDF Reader comes with a virtual PDF printer. This means you can print any document into a PDF file. Similar to to converting for example you can save your word document as PDF file. Nitro PDF Reader also can write text directly into the PDF files. Foxit Reader has a safe reading mode which shall prevent you from malicious documents. PDF-XChange Viewer comes with OCR features. I tried it but the results were not useful at all.
SumatraPDF with it’s minimal concept seems to be the only with absolutely no extra features.
All apps have the basic features for reading/viewing PDF files like different page view modes, zooming in and out and searching the document. I myself stick with Adobe Reader as it has basic features and comes directly from the inventor of PDF files.
If I need a minimal reader and read only few PDF files then SumatraPDF would be my choice. And it also offers the portable version which is quite useful if I need to open PDF files on another computer without installing the app.
If you like the ribbon toolbar and don’t care about 51 MB being used up of your RAM, then you could try Nitro PDF Reader. For direct Adobe Reader alternatives, I would consider Foxit Reader and PDF-XChange Viewer since they come closest to its features and even have a few more extras.
