How to Reduce Excel File Size in 3 Simple Steps?

Step 1: Upload Your Excel File

Simply drag your XLS, XLSX, or XLSM file into the upload area or click the "Select File" button to upload it. There is no limit on the number of files uploaded, and our software can handle:

• Files of up to 100MB in size (10x the limit of most competitors)
• All file types (.xls, .xlsx, .xlsm, .xlsb)
• File uploading multiple files at a time (greatly compressed)
• No signup or logging in required
• Multiple worksheets (all worksheets compressed together)

Pro Tip: Keep your original spreadsheet as a backup, but our compression will maintain all data integrity and formula accuracy 100%.

Step 2: Automatic Compression

Once uploaded, our powerful compression algorithm will automatically:

• Optimizes any and all embedded images and charts
• Strips unused styles and formatting
• Deletes hidden rows, columns, or even entire worksheets
• Compresses embedded objects and shapes
• Strips out unnecessary metadata and cached data
• Optimizes cell and conditional formatting rules

Normal time: 10-25 seconds for anything less than 100MB

Step 3: Download Your Compressed Excel File

Your compressed file is now ready for download! All you need to do is click the download button and:
