Convert multipage TIFF to PDF yields one page PDF

You can open that multipage tiff with Preview, from where you can print it to PDF to DT; you could even automate those steps.

Right. However, that’ll not work on iOS. And I think it would be preferable to have DT(TG) do these things: It would be only a loop over all pages in the TIFF to generate the corresponding PDF page. Programmatically not a big deal.

yeah, perhaps I should have read what you wrote further up :see_no_evil:

Programmatically not a big deal.

That would depend on the OCR engine’s capabilities. @aedwards would be a more authoritative contributor on this.

Converting a multi page TIFF to a searchable PDF is on the list of features that we will add to DTTG OCR .

Is it already part of DT’s OCR, than?

Yes DT’s OCR will convert multi page TIFF’s to a searchable PDF

:+1:

I can confirm that I’m experiencing the same issue. Converting multi-page TIFF files into searchable PDFs is still not working for me either. The TIFF files are imported correctly, but the OCR/searchable PDF generation only process page 1.

Could anyone share the current status of this issue?

Assuming that you are referring to DT 4.2. I tested that here with the big TIFF provided on this page (10 pages). Downloaded, imported in DT, run “OCR to PDF” on it there and got a 10-page PDF+Text document.

I suggest that you provide

  • information about your setup (DT and macOS version)
  • (a link to) the multi-page TIFF document for which you get a single-page PDF after OCR’ing.

Without hard facts, no one will be able to reproduce, much less fix the issue.

Thanks for your quick reply.

So, here’s the thing:
If I select Convert > Create PDF (paginated), it only creates a single-page PDF.

If I use OCR > Create Searchable PDF, it works. Thanks for the tip; I hadn’t thought of that.

But I think the Create PDF (paginated) option isn’t working correctly.

To assist you, what version of DEVONthink and macOS are you using?

It is Version 4.2.2 on OS X 26.3.1 Tahoe

Should I upload a sample TIFF file?

Thanks!

Indeed.

Originally, you said “the OCR/searchable PDF generation only process page 1”. That is apparently not the case. And that’s what I was trying out.
If you want a searchable PDF, just use OCR. If you do not want a searchable PDF, you can stick with the multi-page TIFF, I guess.

Thanks for your help. Using OCR > Create searchable PDF works very well now.

Perhaps the other option should still be added to the bug list. I almost reduced quite a few files to a single page.

This would be useful.

I am seeing an issue with a multipage TIFF.
On my Tahoe Mac, selecting this document in DT4 wil not display it in the view/edit pane. And no subsequent documents selected in this window will display either.

Anyone else seeing this?

On the other hand, it OCR’d just fine if I didn’t preview it first :slight_smile:

I guess it’s kind of shy – it doesn’t want to be seen in public before it got a text layer.

Apart from that: I’m not on Tahoe (trying to just skip that), and on 15.7.3 a multipage TIFF displays just fine.

Just an exception due to some Tahoe incompatibility or bug, will check this.

Tahoe is a… ahem (cough) “mess” :enraged_face: :slight_smile:
