Maximum file size: 100MB per file

XLSX workbooks are packaged archives that grow large mainly from embedded images, charts and stock media. This browser-based compressor reprocesses those heavy assets and repacks the archive at higher efficiency, producing smaller Excel files for email, upload limits and storage savings — while your workbook stays on your own device the whole time.

اکثر پوچھے جانے والے سوالات

How does XLSX compression work?

XLSX files are ZIP archives containing images, charts and XML. Our tool extracts the archive, re-encodes embedded images at optimized quality levels, and repackages the workbook with efficient compression.

Will my formulas and data change?

Cell data, formulas, formatting and pivot tables remain intact. Only embedded images are re-encoded. The workbook will calculate and look the same when opened in Excel.

How much can I reduce XLSX file size?

Workbooks with many embedded images can shrink by 50–80%. Data-only workbooks see smaller reductions, mainly from more efficient archive repacking.

Is this XLSX compressor free?

Yes, completely free with no limits. Process as many Excel files as you need, no registration required.
