Adjust the Compression Levels for your PDFs

Yes you heard that right! KlearStack’s compress PDF tool lets you easily shrink your PDFs as per your desired compression levels.

Usually, it offers you three compression options to pick from:

  • Low Compression:
      • Suitable for minimal reduction in file size.
      • Maintains relatively higher quality.
      • Ideal when a balance between compression and document quality is essential.
  • Medium Compression:
      • Offers a moderate reduction in file size.
      • A compromise between file size and document quality.
      • Recommended for users seeking a balanced approach to compression.
  • High Compression:
    • Results in a significant reduction in file size.
    • Sacrifices some document quality for maximum compression.
    • Useful when minimizing file size is the top priority, and slight quality loss is acceptable.

It is worth noting that—When you pick a compression option, estimated compression rates guide your decision. Compression varies based on your document’s content; text-heavy PDFs compress differently than image-rich ones. Basic compression reduces the file by about 40% with minimal impact on image and data quality. Strong compression may affect image clarity or data quality, so use it judiciously, particularly for online submissions requiring specific file sizes. Avoid strong compression for slight size reductions.
