A file will not upload

  1. Open the file on your computer to confirm it is not damaged.
  2. Remove password protection or encryption before uploading it.
  3. Save older Office files in a current format, such as .docx, .pptx, or .xlsx.
  4. Rename the file with a short, simple filename and try again.
  5. If the file is large, create a smaller copy containing only the pages or sheets you need.
Try a small file of the same type. If the small file works, the original file’s size, protection, or contents are likely the cause.

Important source content is missing

  • Use a text-based PDF when possible. Scanned pages may need clearer scans or OCR before upload.
  • Give documents clear headings and give spreadsheet columns consistent labels.
  • Check that tables, chart labels, and numerical values are readable at normal zoom.
  • Mention the facts or sections that matter most in your prompt.
  • Compare the generated outline with the source before creating slides, then add any missing topics to the outline.

Images are missing, irrelevant, or low quality

  • Describe the subject and visual style more specifically in the prompt.
  • Replace an unsuitable image in the editor instead of regenerating the entire presentation.
  • Confirm that an uploaded image opens normally and has enough resolution for the intended slide size.
  • If every generated presentation lacks images, ask your Presenton administrator to check the configured image or search provider.

If you manage a self-hosted instance

  • Confirm the upload and persistent-data directories are writable and have sufficient free space.
  • Check document-processing logs for parser, OCR, unsupported-format, file-size, memory, or timeout errors.
  • Verify image and search provider credentials and connectivity independently from the text provider.
  • For services running on the host, use a hostname and port reachable from the container rather than container localhost.
Never share a confidential source document just to reproduce a problem. Create a small sanitized file with the same format and structure instead.
