WPS Document Optimization on iOS FAQ

Last updated:July 12, 2026

Common questions about Document Optimization usually focus on image quality, reduction results, and workflow differences; this section covers 3 frequent questions.

FAQ

Will Document Optimization affect document quality?

  1. Document Optimization mainly reduces file size by compressing images and cleaning redundant data.
  2. Text content and layout usually stay the same.
  3. If the document contains many high-resolution images, image clarity may change to some extent, so backing up the original document first is recommended.

What should I do if the file size reduction is not obvious?

  1. Check whether the document contains many images.
  2. If the document has very few images, the reducible space is usually limited.
  3. You can remove unnecessary images or reduce very high-resolution materials first, then run Document Optimization again.

What is the difference between Document Optimization and file compression?

  1. Document Optimization directly adjusts images and redundant data inside the document.
  2. File compression usually packages the whole file without changing the internal document structure.
  3. After extracting a compressed archive, the original file size usually returns, while an optimized document is saved as a smaller file.
