FAQ
Will Reduce File Size affect spreadsheet quality?
- Reduce File Size mainly works by compressing images and cleaning up redundant data.
- Images may be compressed, but the main spreadsheet content is not removed for this reason.
- 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?
- Check whether the spreadsheet contains many images or other compressible content.
- If the file contains very few images, the size reduction may be limited.
- 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?
- Reduce File Size optimizes content inside the document, such as compressing images and cleaning up redundant data.
- Compressing a file usually packages the whole file into a compressed archive without changing the internal document structure.
- If you need a smaller spreadsheet file that is easier to open and share directly, Reduce File Size is more suitable for that scenario.
