How to maintain signatures when combining PDFs

Dear Forum,
I have an issue when combining PDF files, where the original files with electronic signature field added in Acrobat Pro, the signatures disappear. Is there a way to stop this from happening? I've checked the security setting and currently have everything in the summary settings as allowed, but still the signatures won't carry through into the combined PDF.
Anyone have any solutions?

You absolutely can't combine signed files without destroying the signatures, because signatures apply to the WHOLE file, always. Consider using a portfolio instead.

Sorting files when combining pdfs?

Ok, I'm not quite sure how adobe sorts files when combining pdfs, but it seems to be somehow different from MS XP. Anyway, what I want to do is combine a bunch of pdfs together which are labelled A 1, A 2, A 3... However, I'm finding that when sorting them by name in adobe to combine them in the right order that the 1's, 2's, and 3's get grouped together, where they are then not sorted numerically. For instance A 2 gets sorted with A 20 and A 200. Even when I use MS XP to rename (e.g. A (1), A (2)) or use Adobe to extract files from a pdf the files are named in such a way that this always happens. Anyway to get around this without manually sorting the files?
A better example of what happens:
A 1
A 10
A 11
A 12
A 13
A 14
A 15
A 16
A 17
A 18
A 19
A 100
A 2
A 20
A 21
A 22
A 23
A 24
A 25
and so on and so forth... where I would like
A 1
A 2
A 3
A 4
A 5...

Looks like a lexicographic ("dictionary" or "telephone book,") order and not numeric order. You could add leading zeros to have all the file names have the same length.

When combining PDF's, the author is picked up from the first PDF opened. How can I make it use a new author when combining several documents?

Is there a Maximum file size limit when combining pdf files

I am trying to combine files 8 PDF files created with i Explore using Acrobat XI Standard, the process is completed but when opening the file not all 8 individual files have been combined only the first two have been combined, the process shows all eight being read and combined.
I can open and view each of the original 8 individual files and read the content without any issue, the largest of the eight files is 15,559kb and the smallest is 9,435kb
if anyone can assist that would be most appreciated

Hi Tayls450,
This should not have happened as there is no maximum file size limit when combining PDFs.
Please let me know if there are some password protected PDFs also?
Also, I would suggest you to choose 'Repair Acrobat Installation' option from the Help menu.

How to preserve custom page numbers when combining PDF's?

When combining multiple PDF's into one, the custom page numbers are lost.
Example: As four separate files (one page each), the pages are numbered as follows: AC-77, AC-78, AC-79, AC-80. When combining them into a single PDF, the page numbers become 1, 2, 3, 4.
How can I preserve the original page numbers?

What is ' custom page numbers' ? How did you create the page numbers?

Digital signatures and combining PDFs in Acrobat X

I hope that one of you Acrobat gurus can help me out with one or more of these questions:
Is it possible to maintain digital signatures when inserting signed PDFs into another PDF?
Is it possible to remove a digital signature after a signature has been deleted from the page?
Is it possible to change the format of the date and time on a digital signature?

In the simplest sense a digital signature is a special checksum of all the bytes in the bytes in the PDF combined with all the bytes in the digital signature. If the document is changed in any way the checksum changes, so the signature becomes invalid. A valid signature ensures that the document hasn't changed since the signature was applied. That stuff that's shown on the signature field is irrelevant. It's just a pretty picture. The real stuff is going on inside the PDF where you can't see it.
Obviously it gets a lot more complext then this. The signature can be selectively applied so that the certain types of changes are allowed. A signature does not add real protection to a PDF, but Acrobat plays along with this scheme by trying to not allow changes that would invalidate the signature, and logging all modifications to the PDF.
1) There are ways to maintain the visual appearance of the signature on the page. If the permissions have been set to allow it the PDF can be flattened, which also partially removes much of the stuff that's going on internally. But this isn't always possible. I had to solve this problem once for a client, so I wrote a plug-in that strips the signature permissions from the PDF (I'll post this to www.pdfscripting.com sometime soon), after which the the PDF can be flattened, keeping the appearance. But of course, after this point the document has to be considered invalid. For example, if the document was a contract, the flattened version would be good for use in an analysis of say all contracts for a particular year, or for copying legal language to another contract, but it couldn't be used as the basis of a legal dispute.
2) I don't understand this one. Do you mean you're deleting the signature field and some of the internal digital signature stuff is still hanging around causing problems? If you own the signature (or the permissions allow), then a standard form reset will "Un-Sign" the PDF. Inserting PDF pages into another PDF will strip out all this info as well.
3) The stamp appearance is set at the time the stamp is applied, it cannot be changed after this point. It's a lot like a PDF stamp.

When combining PDFs Acrobat XI Pro crashes. It manages to save the newly created document but the resulting crash is really frustrating. Any input would be welcome, thanks!

Just as the post said, I have a user that frequently combines PDFs. When she tries to combine documents, it crashes, although it does save the new document.
The crash takes away from her productivity and she isn't pleased as this was also happening with Acrobat 9 Pro that we just upgraded from. Any ideas on why
this is occurring would be most welcome. Thanks!

Acrobat versions prior to 9 had a bug which allowed you to do what you did. In Acrobat 9 this bug was fixed. In order to do what you want you need to certify (apply special certification digital signature with your certificate -- it is "Certify (Visible/Invisible)" choice in the "Work with Certificates") your document first. In the process of certification you can specify which modification permissions you allow the users of your document to make after signing. Certification signature must be the first signature in the document.

Acrobat 9.5, file corruption when combining .pdfs created from Word or Excel (from Office 2010) into a larger .pdf document

In Acrobat 9, when I combine .pdfs created from Word or Excel (from Office 2010) into a larger .pdf document, there is data corruption. Some of the text appears as blank boxes when the pages are inserted into the larger .pdf, the main document. I have so far solved this by "printing" the files to .pdf, and then inserting them into the larger .pdf main document, but this creates a fatter .pdf file that is much larger than would otherwise be the case. Are there any other solutions within Acrobat 9, please? If this bug has been solved in Acrobat X or XI, please advise. Thanks.

As far as the images are concerned, that may be a result of your choice of job settings. You may want to use the Press or Print option if the image quality is important. I assume you are talking about bit images in this case.
As to the hangup, have you checked to see if AcroTray is active on your system? It may not be running as needed. In the meantime, try checking print to file and then opening that file in Distiller to complete the conversion to PDF.
Before you ever try a reinstall, you need to do a repair first to see if that resolves the problem. There are a lot of unknowns about your exact process for the printing and your job settings that may be part of the problem. The rest of your system setup is useful in some cases, but did not help me see your problem.

Save as pdf deleted bookmarks when combining pdf-files

Hello,
when I save several books each to a pdf-file with save as pdf (or printing to .ps and converting afterwards), the bookmarks are deleted when I combine the pdf-files with Acrobat. Only one bookmark for the 1st. file exists in the new pdf-file.
The reference of the bookmarks in the original generated file is e.g. "g3.619626".
These references are not anymore available in the combined files.
I've tried several settings before saving as pdf but nothing helped.
Ther are no problems of combining ordinary pdf-files with bookmarks if they are generated by other programs then Framemaker.
I need to combine files as well within a book, as "save to pdf" is not able, to generate one file with different pages sizes. I then need to generate a separate pdf-file of the pages with the for e.g. bigger page size and combine it afterwards.
In that project I'm working there will over all something between 1000 and 1500 pages from maybe 10 books with hunderts of bookmarks plus additionally separete pfd files to combine. So it's not an option to treat every bookmark before combining the pdf-files.
My system is FM11.02.384 / Acrobat Pro 11.0.3 / Windows 7 64 Bit

Never having had a need to do it, and Adobe documentation for Acrobat being what it is, I can't tell if AcroPro is supposed to be able to merge bookmarks when merging PDFs. It would be an unsurprising feature, and you do say it works on PDFs generated by means other than FM.
Here's a hack that might work, if the variable-page-size rendering turns out to be out of reach. You can batch* this.
Open each component PDF and re-save it with some otherwise harmless optimization (or even none). This will probably cause AcroPro to re-write the internal structures of each PDF, which might then be amenable to merged bookmarks when you re-open them for merging.
* We do a similar thing for a slightly different problem. We have a software-in-a-box XML publishing app that, at just some seats, is generating PDFs that are tagged for byte serving (fast web view), but are not in fact encoded for it. This causes AcroReader plugin and entire browser crashes for web end users. The s/w vendor can't even tell us where the option is for controlling that feature, because they get the PDF gen code from some other 3rd party. So we routinely batch process all generated PDFs, with, oddly enough, NO "commands" selected. The re-save alone fixes it.

Keep unique page numbering when combining PDFs

I have a series of PDFs that I am combining for a project, but I need to keep the unique page numbering found in each file. Each PDF is a volume in a set and has page numbering like "v1 100" for page 100 of volume one. There are also seperate page numbering styles for unnumbered pages that have images. This is done so that each page has a unique page number in acrobat that matches the number on the image of a page.
However when I combine PDFs it throws out all of the page numbering and goes back to 1, 2 ,3, etc. If I open the first PDF and insert the second at the end it just sets the whole second volume to have the page numbering schema for the last page of volume one.
Does anyone know of a solution for this problem? I don't want to go through 1000+ pages of renumberingagain.

Corrupted characters when combining pdfs

I am trying to combine a set of files into one pdf document. Each pdf file was created from Microsoft word and they all display perfectly as single files.
However when I combine all the pdfs into one document a lot of the text becomes corrupted and displays as square boxes instead of the correct characters.
Can anybody help please?
Thanks
Steve

I am not sure Preflight is part of Standard. If it is, you will find it under the Advanced menu. However, it appears that the embed fonts is not one of the profiles for AA8. AA9 has an embed fonts profile. If you have all of the original files available, the fastest approach might be to go back to the original files and recreate the PDFs, selecting the Press or Print job options. For combining, you may have to change the job options to not embed subsets. Sometimes the use of subsets causes problems when combining. Before you waste time on a whole set of files, I would suggest you play with 1 or 2 to see if things work out. I hope this process resolves your issues. Basically, all I am suggesting is what I would try to make it work. You can also use ctrl-D in Acrobat to get the document properties and check the font embedding under the font tab. If it does not say embedded, then it is not embedded.

How to remove pages when combining 2 pdfs into a single document?

I renewed my subscription to Acrobat for $89.99 in order to combine 2 pdf documents while removing a page from one. I used to be able to select the pages from a document prior to combining the 2 documents. Now there does not appear to be an option to select pages for combining... What am I missing?

You said in your first message that you subscribed to Acrobat. Our replies were about Acrobat. Indeed, PDF Pack doesn't enable any of those things.

Lose form data when combining PDF fillable forms

I would like to combine into one PDF document two completed form-fillable PDFs. The PDF forms have identical fields, but the data collected on the forms (from different users) is different, of course.
When I add the second form to the PDF document containing the first one, the data from the second form is erased and replaced by the data from the first.
So, I end up with a PDF document with two forms containing identical user data.
I suspect Acrobat is freaked out because the forms contain the same field names or something. I know I can solve this by making a new PDF from the form-fillable PDF--flattening the layers, in Photoshop-speak. Is there another way to solve the problem?

With Acrobat forms form fields with the same name and type will change together. This has how Acrobat forms have worked since they were introduced.

Error when combining PDFs in Acrobat 4.0

My workstation is a bit of an older computer and it only has Acrobat 4.0 so I'm hoping people will remember enough about it to help me. I've been making several PDFs out of a large group of old Word Perfect documents and I need to combine them into a single PDF. It has been going well for the first 8 parts, but the 9th and 10th are giving me an error message. It says that "These documents contain subset fonts that have the same name and cannot be merged."
I'm hoping someone here will know what that means and will be able to advise me on how to solve this problem. Thanks.

I'll give that a try, thanks. It's a fairly old set of files I'm working on so it would be great if I can make this work for a single integrated PDF.
If you do have AA4.0, I would appreciate it if you would check that as well. The files are going to come out to around a 250 page document when I get them all assembled and I'm not sure exactly which fonts are causing the trouble yet.
