PDF loader is very slow on windows

the PDF opener, especially with annotations and large files takes forever to load or does not load at all. Even scrolling is not seemless.

I am on windows. I do not have this issue on ipad/iphone.

Thanks for letting us know, @Shubhang_Bhalla; that shouldn’t be happening. To help us investigate, could you share a few more details?

  • Which browser are you using on Windows (and version, if possible)?
  • Does this happen with all PDFs, or only certain ones (e.g., very large files, heavily annotated papers)?
  • Roughly how large are the files (MB and/or page count)?
  • Do you notice high CPU or memory usage when the PDF is loading?

Could you please email our support team at support@paperpile.com with one or two example PDFs? Having concrete examples will allow our team to try to reproduce the issue and pinpoint what’s causing the slow loading and scrolling.

Windows, using any browser: chrome, edge, arc, or zen.

All PDFs but especially the heavily annotated one
