How to reduce PDF file size for scanned documents

When working with scanned documents, the goal is not only to create a lighter PDF. You also need to turn photographed or scanned pages into a more useful digital document. This guide covers a short workflow, the checks that matter and the limitations to understand before using the output.

Why this workflow helps

Compress PDF is useful when you need to reduce PDF file size without installing desktop software. The source is uploaded for temporary processing, then you download the result to your device and keep the copy you need. For scanned documents, a repeatable workflow reduces mistakes involving filenames, page order and outdated versions.

Recommended workflow

  1. 1

    Prepare the source for scanned documents, close unfinished edits and keep an untouched backup.

  2. 2

    Start with lossless optimization and compare output size before considering lower image quality.

  3. 3

    Run Compress PDF, download a lighter PDF, and open it before sharing or archiving.

  4. 4

    Use sharp, upright pages and verify OCR characters where accuracy matters.
