Acrobat Applescript For ScanSnap OCR
September 5, 2008
Hi there. If you're new here, you may want to subscribe to my RSS feed. Thanks for visiting!
This was referenced in my ScanSnap workflow series, but I thought I would provide it in its own article as well.
I have a ScanSnap S300M and Adobe Acrobat, and was getting pretty tired of sitting there OCRing the PDFs manually in Acrobat.
I came across this article by MacWorld which had a great Applescript Folder Action that would kick off Acrobat’s OCR whenever a PDF was dropped into the folder.
It worked well but I found that then I had to sit there and watch the OCR go after each document, and it seemed to have problems if I scanned another file while the OCR was still going.
I wanted a solution where I could just throw a bunch of PDFs at Acrobat and walk away.
Thanks to this thread on MacScripter, I turned the Macworld script into a droplet. Now I just go through and scan a bunch of PDFs to a folder, then drag the files onto the droplet, and go to bed. Acrobat OCRs each one one by one.
Here is the script. You can download it for free, but make sure you go to the Macworld article because it is 90% his work.
To use it:
- Download and uncompress the file and save it to your Desktop, Dock or wherever
- Drag one or more PDFs onto the icon
- Enjoy
Update: User nodis in the comments pointed out a great optimization that makes significantly smaller PDFs. Thanks!
Here is the source code:

Got something to say?
Get Updates!
Man, I love you!!!!!!! I can’t tell you how long I’ve been looking for something like this. It’s just perfect!! THANK YOU! THANK YOU! THANK YOU!!!!!!!!!
Ha, no worries at all Dave. I mostly just built on what other people had done, but glad I could help!
I get an error message when I drag a file into the Droplet. It says "Sorry an error occurred. Access for assistive devices is disabled (-1719)" How do I get this droplet to automatically OCR my files? Thanks for your help!
Ok…I figured it out. I had to adjust the settings on Universal Access in my Mac. Now, how do I do multiple files at once???
Hi Barry, you got it- universal access. Good job!
For multiple files, assuming you've saved the droplet somewhere, all you need to do is drag a bunch of files onto the icon. It'll then OCR them one by one.
Let me know how it goes!
you rock the house. thank you so much for this. This saved my life.
Hah thanks! Glad to hear it helped out.
hi. anybody else know why the size of the document increases by as many as 6x when you run a PDF through this script. it works great – but the size increase is substantial. unless i am wrong, only text should be added plus some location information, and therefore size should not go up by as much.
is it possible to have a version of this script where the size of the document does not super expand!?
thanks.
Hi,
Thanks for the nice script.
I have a problem withe the saving command.
How can i save this file as a txt.
thanks in advance.
regards
Antony
@antony
You can just highlight the code in the post above, Copy, and then Paste it into your text editor of choice. Then just File Save As to a .txt extension if that is what you want.
this looks great but it does not work for acrobat 7.0 standard. i tried to modify the script but it kept throwing up errors. can you please attach the script file as text? i suspect the copy paste from the site may be messing up the formatting although i cant be sure.
@pendolino I haven't tried with Acrobat 7 so there may be some tweaking required. Here is the script in txt format: http://www.documentsnap.com/files/OCRIt-Acrobat.t...
Thanks for writing this applet and making it available, I am looking forward to using it.
I am having trouble using Adobe 7.0 professional. Dragging a pdf file on the droplet opens the file in acrobat but an error window quickly appears saying
"System Events got an error:Can't get menu item "OCR Text Recognition" of menu "Document" of menu bar 1 of application process "Acrobat". (-1728)
Could you please tell me what this means and perhaps offer some advice on how I might fix it. Would using Acrobat 9 solve my problem? I have never written/edited and applescript but I'd be glad to have a go if necessary.
Thanks
Hi Rodger,
I don't have Acrobat 7 so I can't look into it, but I am guessing that it must be something to do with differences in the menu between 7 and 8.
Basically if you look at the script, the code needs to match the menu titles exactly.
If you'd like, if you can send me screenshots of each step of the Acrobat 7 Ocr process, I can probably make you a 7.0 version (assuming you can script to 7).
You can send them in an email to brooks@documentsnap.com.
Hacked script to work with Acrobat 7.

Nice, thank you so much Phil!
Great tip, but the script needs one modification. The line in the AppleScript where the document is saved should be changed to:
save the front document with linearize
This is the equivalent in scriptese as saving as "optimized" (or a "Save as…"), which results in a lot of Cruft being thrown away and the saved PDF optimized for progressive Web download. When I run the script on test OCRd PDFs, both with and without this change to the AppleScript, I get ~95% smaller PDFs with this change (note that this is also with Acrobat's new ClearScan OCR method selected — the new default).
hi @nodis: can you point to exactly which line should be changed.
i have not been using this script essentially because the PDFs become bloated.
and i am unable to understand why addition of scanned text should lead to any bloating! perhaps you have found the answer!
Not a big deal. I must say that the difference in size and quality between OCR-ing PDFs using the latest ABBYY FinePrint for ScanSnap and Acro 9/ClearScan OCR downsampling at 600 dpi/and your droplet is amazing.
I just scanned a 25 page B&W Word document. The original image-only PDF is 6.2 MB. ABBYY produces an OCR-ed PDF that weighs in at 10.5 MB choosing "High" quality; it is 1.8 MB at Medium quality (and looks like crap visually at Medium quality, I should add — lots of compression artifacts).
By comparison, using your Applescript droplet, with the edit I suggested, along with Acrobat 9 and the "ClearScan" and 600 dpi OCR options, my OCR-d PDF comes out at 356 KB. This version looks superb, and the OCR quality seems fine.
I don't in any way mean to knock ABBYY — but the size/quality ratio of Acro 9+ClearScan 600dpi+your AppleAScript is just absurdly good. I'm frankly surprised not to see Adobe market this feature more — or Fujitsu, their OEM scanner partner.
Msim,
The line that needs to be changed is towards the end:
save the front document
One simply adds "with linearize" at the end. As you will see below, our intrepid host already plans to make this change.
On Adobe's Web site, linearizing a PDF is described as follows:
"A linearized PDF document is organized to enable incremental access in a network environment. For example, a linearized PDF document can be displayed in a web browser before the entire PDF document is downloaded."
Old versions of Acrobat (like version 3) described this same thing as "Optimizing."
For whatever reason, "linearizing" the save from within the AppleScript causes a bunch of redundant data in the OCR-d PDF to be thrown away, resulting in a much smaller file.
OK everyone, I have updated the post and posted the updated version at http://www.documentsnap.com/files/OCRIt-Acrobat-1... with nodis' changes. Thanks again!!!
The linked app requires me to install Rosetta. Since I do not need it for anything else, I have avoided it. Is there a way to save the script in AppleScript editor and use it without Rosetta?
I tried to copy and paste it into AppleScriptEditor. Upon saving the script it asked me to help it locate Acrobat, which I did by point it to "Adobe Acrobat Pro.app". But then it failed and pointed me to this line in the script – tell application process “Acrobat”.
The cursor is at the " before the ACrobat in the line above and I receive a Syntax Error – Expected expression, property or key form etc but found unknown token.
Any ideas? Thanks!
Hmmm. You're right. The revised script is saved as a PPC app, as opposed to Universal. You can fix that easily though.
In Snow Leopard, launch AppleScript Editor (you'll find it in your /Applications/Utilities folder). Open the revised droplet from within ApplesScript Editor. Choose "Save As…" to re-save and, voila, a Universal version of the app.
Hi guys, I've replaced the linked file with one that should be Universal. Sorry about that!
thank you guys.
this one works and works beautifully!
