Advantage: understood to be a final format. Disadvantages: bigger,impossible to analyse, still editable (with more work).Ĥ. Disadvantages: much harder to analyse, no security, still editable.ģ. Advantage: small, easy to analyse, easy to reimport as required. Export the form data and archive only that. You seem to have decided on your workflow, but just in case here are some thoughts on archiving filled in forms. Now the question is, how do I batch remove the extended features from a folder of files to enable the preflight flattening? but if I "Save a Copy…" to disable the extended features for editing in Reader, the preflight flattening works. Permissions can be restricted by using encryption or digital signatures." "Preflight is unable to perform any fixups on this document as its author did not grant the necessary permissions. Creating action for Preflight > Flatten Annotations and Form Fields doesn't work, as preflight errors: and the values need to be unique but PDF Portfolio is not an option. To create a PDF Portfolio, choose File > Create PDF Portfolio."
If you want the values in these fields to be unique, then you need to create a PDF Portfolio instead of merging the files. "Any form fields that have the same name in the merged documents are now merged into one field. Because the form fields are named identically, the Combine Files gives error: Hello! I need to combine a number of Acrobat Reader Extended PDF forms - filled in by clients - into a single combined PDF with the form fields flattened. If your forms were digitally signed by the person who filled them in then all this would be moot, as every possible change would be detectable. None of those things are possible with bitmaps. PDFs are searchable, they can be digitally encrypted, they are accessibility-compliant and you can control who opens them with DRM.
You don't turn it into a screenshot - as that would also be editable to anyone with Photoshop and the changes would be completely undetectable. If you want to stop someone with Acrobat Pro from making edits to a PDF file, you apply security to it.
Turning something into a bitmap is called rasterising, and to Acrobat it makes no sense as part of a forms workflow, as the end result is no longer a PDF file. The PDF file remains editable in Acrobat Pro, because that's what Acrobat Pro is designed to do. Flattening does not merge layers, it does not combine text an image objects, it does not create outlines. It refers to the process of turning annotations and markup into regular page content nothing more, nothing less. "Flattening" has a very specific meaning in PDF, and you're not using the term properly.
