About compressing XLSX
Excel files are already compressed internally (XLSX is a ZIP archive), so gains are smaller unless the sheet has embedded images or charts.
Compress a spreadsheet before sending it to a colleague or uploading it to a shared drive with limited storage.
Typical size reduction
Expect modest reductions (10-30%) unless the file has large embedded images.
Frequently asked questions
How much smaller will my XLSX file get?
It depends on what's inside the file. Expect modest reductions (10-30%) unless the file has large embedded images. Preview all three levels before you commit, no guessing.
How do I compress a XLSX file?
Upload your XLSX file above, pick a compression level, and download the smaller file, all done instantly in your browser.
Will compressing my XLSX file reduce quality?
Lighter compression preserves more visual quality; stronger compression trades some quality for a smaller file. Preview the size before you choose.
Can I compress multiple XLSX files at once?
Yes. Upload as many XLSX files as you want and compress them all together, then download individually or as a zip.
Are my files stored anywhere?
No. Your file is processed just long enough to compress it, then discarded immediately: never stored on disk, logged, or shared with anyone.
Is compressing XLSX files free?
Yes. Compressing XLSX files on Other Streets is completely free with no limits.
