Delete single pages of a pdf

[Skylinar]

Hi all! Great to see new activity on the project!

Several scanners have the ability to scan double-sided. Since there are multi-page documents where not all pages are printed on both sides, there are usually blank pages in the pdf. It would be wonderful if it would be possible to delete individual pages of the pdf.

Does anyone have the expertise and the time to implement this? This would be aweseome!

would also be generally nice to have for any pdf, with "unnecessary" pages 👍

What scanner & scan software are you using? I am using a Brother scanner and Brother iPrint & Scan software, and the software does support detecting blank pages which are then excluded from scanned documents. This does work quite reliably for me, using the highest sensitivity level:

Im using the Epson WorkForce WF-7710. Its a good hint, I will check if Epson has such a feature you mentioned.

For me it's quite often the case empty pages are not recognized reliably, or the content of the other page is not relevant for the document. So it would be wonderful to be able to delete pages of a PDF.

Would also to have that sort of feature where you could basically set a threshold for detection of a blank page!

Actually I do have a scanner with automatic detection of blank pages, but it doesn´t always work reliably, so I would opt for a general GUI feature to mark and remove certain unnecessary pages from a document.

Example workflow:

• Put bunch of papers that belong together into scanner which get automatically scanned to consume folder
• Verify scanned document in Paperless (should be done anyway to detect any issues)
• Mark & remove unnecessary content

Examples of unnessary pages after a weekend of scanning hundreds of documents:

• blank pages but "hole punched", often not detected correctly by scanner
• sometimes documents are printed on "patterned" paper, so even the back, while empty, contains the pattern (example: insurance contracts)
• sometimes documents contain an ID number or "weird" pattern on both front and back even when back page is empty (lots of communication from insurance companies!)

I hope these examples show valid use cases.

I´m afraid that such a feature might be a little more complicated because once it´s possible to delete any page froma document, afterwards OCR needs to be redone as the page could have contained text.

+1 for another scenario:

I use PATCHT barcodes to separate multiple documents, and I use pastel paper for the codes.

The pastel paper is never picked up as a blank page by the automatism of my scanner, regardless of the sensitivity, the moment I put it into colour scan mode.

… now I have a load of documents that have a light green first page ... 🤦🏼
