FAQ

Will Reduce File Size affect spreadsheet quality?

  1. Reduce File Size mainly works by compressing images and cleaning redundant data.
  2. The spreadsheet structure itself is not converted into another file type.
  3. If the file contains many images, image display quality may change to some extent.
  4. For important files, choose to back up the original file before processing.

What should I do if the file size reduction is limited?

  1. First check whether the spreadsheet contains many images or redundant items.
  2. If the file already contains few images, the reduction result may be limited.
  3. You can remove unnecessary images or repeated content first, then run the feature again.
  4. After that, review the before-and-after size comparison again.

What is the difference between Reduce File Size and standard file compression?

  1. Reduce File Size works on content inside the document, such as images and redundant data.
  2. After processing, the document itself becomes smaller.
  3. Standard file compression usually packages the file, and the original size returns after extraction.
  4. If your goal is to reduce the spreadsheet file size itself for ongoing use, Reduce File Size is the more direct option.
