I am unable to upload some PDF files to my Library

While our algorithms do a good job distilling the majority of PDFs into their key facts and findings, sometimes they struggle! If you find that a particular PDF does not upload, try one of the following:

  • If the PDF is a scanned image, run it through OCR software first. There are both free and commercial software available for this.
  • If the PDF is a complete book, try breaking the PDF down into separate chapters, and upload one chapter at a time
  • If the PDF is very large or many pages long, try breaking it down into smaller files and upload each of these separately
  • If the PDF contains many figures and images, try switching off Extract Figures in Settings > Import.
  • Send us the PDF and we’ll investigate
