Frequently asked questions
Compress Excel FAQ
Select a question to view the answer.
Open Compress Excel, choose your Excel file, select an available compression level, start compression and download the resulting file.
Not necessarily. Some documents are already highly optimized. Where compression does not produce a smaller safe output, the tool may preserve the original data rather than force an inferior result.
No. The original source file remains separate from the downloadable compressed result.
The current Fylvexa document-compression implementations are designed for browser-side processing and do not require a Fylvexa compression backend.
Use a lighter setting when document quality is more important and a stronger setting when reducing file size is the priority.
Yes. Browser-side compression uses your device memory and processing power, so larger or image-heavy documents may require additional time.
