Will my formulas still work?

Yes — the workbook's content doesn't change, only how its pictures are stored.

My file has no pictures — will it shrink?

A fresh, tightly packed .xlsx is often smaller anyway; huge data sets stay big, since every value is kept.

How much does it cost?

You can open your file, convert it and check or change everything in the studio before you pay anything. Downloading the finished file is part of every MojoPDF plan — start with the 7-day trial for $1 and cancel any time.

Is it safe to use Compress Excel File here?

Yes. Your file travels over an encrypted connection and stays private to you — nobody else can open it. Projects you save are kept in your account until you delete them, and download links we email you expire after 7 days.

Why Excel files get big — and how to shrink them

Big Excel files are usually big because of pictures (logos, product photos, pasted screenshots) and loose packing. This tool rebuilds the workbook as a fresh .xlsx — which on its own often drops the clutter that old files collect — shrinks every picture to a sensible size and packs the file at the highest compression. Your data, formulas, formats and charts don't change. Choose Light, Balanced or Strong, and the new size shows before you download.
