FAQ

Will Reduce File Size affect spreadsheet quality?

  1. Reduce File Size mainly works by compressing images and cleaning up redundant data.
  2. Images may be compressed, but the main spreadsheet content is not removed for this reason.
  3. If you want to keep the original version, choose to back up the original file before you start.

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

  1. Check whether the spreadsheet contains many images or other compressible content.
  2. If the file contains very few images, the size reduction may be limited.
  3. You can also remove unnecessary images or content and then run Reduce File Size again.

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

  1. Reduce File Size optimizes content inside the document, such as compressing images and cleaning up redundant data.
  2. Compressing a file usually packages the whole file into a compressed archive without changing the internal document structure.
  3. If you need a smaller spreadsheet file that is easier to open and share directly, Reduce File Size is more suitable for that scenario.
