Interactive PDF fields and flat scanned forms behave differently. Scanned forms may require text overlays.

File handling

  • The page states the intended file types and output before upload.
  • Quality limits are explained so users know what to review.
  • The tool avoids making guaranteed layout, privacy, or accuracy claims.
