Upload, preview and extraction are separate operations. A file may remain downloadable even when PutBoard cannot create a rich preview or extract useful text.
What to check
- Confirm the file is one of the supported formats and is within the size limit shown by the form.
- Open the original locally to confirm it is not damaged or password-encrypted.
- Export unsupported Pages, Numbers or Keynote documents to PDF, DOCX, XLSX or PPTX.
- Upload again; if the problem persists, contact Account support with the content type and filename but no sensitive data.
Good to know
- Image-only scans need OCR before upload if their words should be searchable.
