When using Reduce File Size, users often ask about 3 areas: compression results, document quality, and feature differences; this section covers 3 common questions and a short glossary.

FAQ

Will Reduce File Size affect document quality?

  1. Reduce File Size mainly lowers document size by compressing images and cleaning redundant data.
  2. Image quality may change after compression.
  3. Text content and layout usually remain unaffected.
  4. If you want to keep the original result, back up the original document before starting.

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

  1. Check whether the document contains many images.
  2. If the document has only a few images, the available reduction space is usually limited.
  3. You can remove unnecessary images or replace them with smaller ones and try again.
  4. Use the before-and-after size comparison to judge the result.

What is the difference between Reduce File Size and compressing a file?

  1. Reduce File Size works on images and redundant data inside the document.
  2. After processing, the document itself becomes smaller.
  3. File compression usually packages the whole file without changing the internal document content structure.
  4. After extracting a compressed archive, the file usually returns to its original size.
