How many pages of a document can Reduct handle?

Under 1,000 pages, a document works normally with no setup. Between 1,000 and 10,000 pages it still works, although it may get slower. Past 10,000 pages, performance drops off enough that you are better off splitting the file first.

The number that matters is the page count of one file, not the total across your project. A project holding a hundred separate 200 page files is fine. One 20,000 page PDF is not.

What to do with a document over 10,000 pages?

Step 1: Try to work out which pages you actually need.

A 40,000 page phone extraction is not 40,000 pages of evidence. Most of it is metadata that nobody reads. The material you care about usually sits in a block: photos from page 3,000 to page 14,000, messages somewhere else, call logs somewhere else again.

Step 2: Split the file

If you exactly know what part of the pdf you need to split, you don't have to worry about splitting the entire file. If not, you can just split the big pdf into multiple smaller chunks entirely.

Aim for pieces under 1,000 pages where you can. Under 10,000 is what Reduct supports. But under 1,000 is where it feels fast. You do not need extra software to slip the PDF.

On a Mac

  1. Open the PDF in Preview.
  2. Go to File, then Print.
  3. In the Pages field, set the From and To range you want, for example 3000 to 3999.
  4. Click the PDF dropdown at the bottom left of the print window and choose Save as PDF.
  5. Name the file so the range is visible, for example
    Jones_Cellebrite_p3000-3999.pdf
  6. Repeat for each range.

On Windows

  1. Open the PDF in Microsoft Edge or Adobe Acrobat Reader.
  2. Press Ctrl + P.
  3. Set the printer to Microsoft Print to PDF.
  4. Under Pages, pick Custom and type the range, for example 3000-3999.
  5. Click Print, then name and save the file.
  6. Repeat for each range.
đź’ˇ Pro tip
Put the page range in every filename. When you find something on page 47 of part four, you will want to trace it back to where it sat in the original.

Step 3: Upload all the splitted pieces

Drag the split files into the Documents tab as separate documents in the same project. Search, labels, and highlights all work across the whole project, so the pieces stay connected for review even though they are separate files now.

This is useful when you need to search a phone dump for a name or a date. Instead of waiting on a single enormous file, you get results back at normal speed and can still see every match in one place.

đź’ˇ Note
Splitting a PDF this way keeps the pages and the text, but drops bookmarks and internal links from the original report. If your workflow depends on those, email support@reduct.video before you split.

If the file will not split with the steps above, or you are not sure which sections matter, email support@reduct.video. Tell us roughly how many pages the file is, which tool produced it, and what you are trying to find.

That is usually enough for us to suggest a split.
