File too large or unsupported

Getting an error when uploading a file? Here's how to resolve common issues.

File too large

Maximum file size is 1 GB.

Solutions

For PDFs:

  • Compress using Adobe Acrobat
  • Split into multiple smaller files
  • Reduce image quality if the PDF contains many images

For Excel files:

  • Remove unnecessary worksheets
  • Delete unused rows/columns
  • Save as .xlsx (not .xlsb or .xlsm)
  • Remove embedded images if not needed

For images:

  • Reduce resolution (300 DPI is sufficient)
  • Use JPEG instead of PNG for photos
  • Compress using image tools
