About XLSX compressor
This page helps you reduce file size for an Excel spreadsheet such as XLSX. Reduce XLSX size to 500Kb, 200Kb or even 100Kb. Upload the file, choose a compression level and download the smaller result. The compressed file is smaller to store, upload and send.
Spreadsheets grow as you add worksheets, formulas and images, and a large Excel file can be awkward to attach to an email or upload to a portal. If a workbook is too big to send, or you want to free up space on your drive, a file compressor makes it easier to store and share. This works for Excel formats such as XLS and XLSX.
Upload your file by clicking the drop area or dragging it onto it, then choose one of three compression levels: Extreme, Medium or Low. The XLSX compressor then removes data the document does not need, such as metadata and unused templates, and optimizes its images. The page shows the new size, and you download the compressed file.
XLSX compressor features
- Control the result with three compression levels: Extreme for the smallest file, Medium for a balance, and Low for higher quality.

- Compress an Excel file for free, with no registration and no account to create.
