Frequently Asked Questions

Will this break my Word or PowerPoint formatting?
Absolutely not. We only compress the heavy media (like photos and graphics) embedded inside the document. The actual XML structure, fonts, and layout remain completely untouched.
How do you make a PowerPoint smaller?
We scan your PPTX file, find all high-resolution images across your slides, and compress them to screen-friendly resolutions. This often reduces the presentation size by 60-80%.
Is it safe to upload confidential business reports?
Yes. Your documents are uploaded via secure 256-bit SSL encryption. They are processed automatically by machines and permanently purged from our servers within an hour.
Can I compress Excel spreadsheets?
Yes! If your XLSX file is massive due to embedded charts or images, our tool will optimize those assets and shrink the file.
