Accessible Lightweight PDF Viewers


Bhavya shah
 

Dear all,

I currently have a 144 mb file that is one of my Physics textbooks.
From the file size, it is easy to infer the massiveness of this
document. Hence, opening it in Adobe Acrobat DC is not always
practical as it takes an infeasible amount of time to load all pages.
Hence, I am in need of some alternate accessible PDF viewing solution
which is relatively lightweight and is likely to be substantially
quicker in loading a large PDF for viewership.

Alternatively, another approach towards addressing my needs that I can
think of is to split this huge PDF into a bunch of different PDFs
which individually are smaller files and thus likely to be faster to
open. In case you are aware of some tool to split a large PDF file
into a few smaller ones, I would appreciate if you could share those
as well.

I am open to using both of the above approaches simultaneously for
maximally mitigating the current problem as well, if need be.

Thanks.

Is there any reason not to load the document one time then save it as a text file?  That's what I usually do with PDF files so as not to waste time converting the document more than once.

Hi,

I'd recommend QRead for this purpose, although not sure if it's exactly
what you're looking for.

I have encountered some recent pdf files that seem to have save as text either disabled or what you get afterwards is a bit like throwing a lot of words in the air and expecting them to make sentences afterwards. I imagine this is the untagged document problem again. Many of the documents my local council issues are like this and often also contain graphics and maps so trying to use the webbie tool also ends in tears.

I'd suggest the webbie PDF reader because it has OCR built in, but you could also upload it to Google Docs and have Google OCR it for you, if needed, You can then publish the text as a web page, download it in basically any format you wish.


 

Bhavya,

          I'll try to cover both bases.

          The first is a utility for splitting or merging PDF files.  I absolutely love PDF Split and Merge, more commonly called PDF Sam, which is free and open source.  I have used the Basic version for both purposes.  I cannot speak to how accessible it is, but even if it were 100% accessible if you can get a sighted assistant to find the actual PDF pages where your chapters would need to be split out and to enter those quickly it will save you a lot of time.

           I have also repeatedly posted about Tracker Software's PDF-XChange Viewer, which, while not 100% accessible (or even close, really), it has top notch OCR capabilities that are accessible in multiple languages and where, after OCRing the PDF file, you can just save the text layer integrated with the PDF itself, so it can be opened in Adobe Reader or the reader of your choice and never need to be OCRed again.  Even though they list this as discontinued, it is only further product enhancement that has been discontinued.  They have been issuing other types of updates since it was designated as discontinued.  What follows are the instructions I wrote up for a couple of my students who were graduate students who seemed to constantly be getting old and arcane material that had been image scanned to PDF long before the age of OCR upon scan became common.   I have also used the language packs that are available for PDF-XChange Viewer with a private client who is a translator, and she has told me that the Swedish OCR capability is every bit as good as the English has been for me.

Dealing with Image Scanned PDF Files

Using PDF XChange Viewer to perform OCR on any PDF you receive that is an image PDF, step-by-step:

1.     Open PDF XChange Viewer from your start menu.

2.     Hit ALT+F,O to bring up the file open browsing dialog.

3.     Hit ALT+I to jump directly to the Look In combo box

4.     Hit down arrow to get into the area that’s somewhat, but not exactly, like the tree view in Windows Explorer.

5.     Hit L until you hear, “Libraries,” announced.

6.     Hit TAB two times, you should hear, “Documents”.

7.     Hit SPACEBAR to select the Documents library.

8.     Hit ENTER to open the documents library.

9.     Hit the first character of the folder or file name you’re trying to perform OCR on. Keep doing this with the first character until you hear its name announced.

10.                        Hit Enter to open the file or folder.  If you’re dealing with a file at this step go straight to step 11.  Otherwise, do the following

a.     If you know the file is in this folder then use the “hit the first character” technique to locate it and jump to step 11 once you have.

b.     If you need to drill down another folder level go back to step 9.

11.                        Hit ALT+O to open the file in PDF XChange Viewer.

12.                        Hit CTRL+SHIFT+C to open the OCR dialog box.  Immediately hit ENTER to initiate the OCR processing.  The length of time this takes depends on the size of the file being processed.  JAWS does not read the processing status box, but will announce the file’s name with star after it when the processing completes.  That’s how you’ll know it’s done.

13.                        Hit ALT+F,S to save the file and its OCR text into the original file itself.

14.                        Hit ALT+F4 to close PDF XChange Viewer.

I've experienced good results from the PDF viewer included in Google Chrome (both under Windows and Mac). I haven't run Adobe Reader for quite a while now, as Chrome tends to give as good, if not better, presentation of many of the PDF files that I read. The rest are images that require OCR in any case.

Microsoft word 2016 and later can open PDF files too.
