The Main Reasons Why Your PDF is Not Clear

Here are the possible reasons why your PDF is not clear or appears to be blurry.

  • Scanning mistakes. Blurry pages are frequently the consequence of scanning errors like machine bumps or scanning on a dirty plate.
  • The original file is set in low resolution. A low-resolution image will make the document look pixelated or of bad quality.
  • Compressions. Keeping your PDF small for viewing and sharing may help save storage space, but this will also affect its quality. There are instances that your default settings may not give you high resolutions. So it is best to always check the settings to see if the output is set to the best resolution.
  • Incompatibility. This usually happens when you are working with someone as you are not sure if their file is compatible with your device or software. The results are usually a messed up output or will give you a bunch of random numbers and letters. Converting it to third-party software may not always give you the best resolution output.
  • PDF Viewer. Users frequently assume that the PDF is broken. But, there are chances that the PDF Viewer is at fault, and in most cases, users typically zoom the document resulting in not displaying its actual resolution. Zooming in may look not as sharp and smooth as what is displayed in the print preview because the PDF Viewer and Print Preview may use different default DPI Settings. To fix this, change the settings to its normal viewing rather than zooming in.
  • Unreliable PDF converter. This may result in producing pixelated or blurry output if the tool or software you are using is not safe and reliable.
