Why does Smaller 100dpi PDF take Longer to Split into Single Pages than Original 600dpi PDF?

Post by NoteApplicabble »

When I attempted to split this already compressed down to 100dpi file into separate pages using PDF-Tools it brought my entire computer to a crawl. (mouse courser, etc. freezing as it moves across the screen, "Alt+Tab" not bringing up open applications on the computer, not opening Task Manager, etc.) The file opens as normal in every PDF application I try... so I don't think it is a completely corrupted file issue.

But when I go back to a copy of the 600dpi version of the same PDF document the splitting into individual pages finishes quickly with no adverse effect to the computer performance while PDF-Tools runs.

Any recommendations on what might be going on?

I am preparing to process lots of large PDF files that will be arriving already at 100dpi in the future. This 100dpi file I compressed with Libre Office Draw.

Any advice on how to avoid bogging down an entire computer and PDF-Tools would be greatly appreciated!


UPDATE:
I re-compressed the 600dpi pdf down to 100dpi in Draw and the new re-compressed PDF is slow to split into individual pages like the original file 100dpi file was.

Sorry, I thought I uploaded the file, but it was too large.

Hello, NoteApplicabble

Thank you for the report, The only immediate advice I can give is to try disabling the "multi-threaded processing mode" if it is enabled, as that should restrict PDF-Tools to a single core to prevent it from eating up too many system resources.

If that does not help, I will need to ask you to send us a copy of the documents directly.

If they are under 25MB, you can send them via email to support@pdf-xchange.com with a link to this forum topic.

If they are larger than 25MB, you can use our useruploads server, as detailed here, to upload the files (please place them in a zip folder with an obvious name, then email us via support@pdf-xchange.com to inform us of the name and that the files have been uploaded. Again, please include a link to this forum post as well.

Kind regards,
