Input: PDF, image, DOCX, PPTX, or XLSX up to 20 MB · Output: smaller file in a compatible format
Quality boundary
The compressor routes each supported file to a format-aware local engine. PDF, image, and Office formats use different methods, and an already optimized source may not become smaller.
How this file is processed
The file stays on this device during processing. Review the result before consequential use.
Read the file compression guide
Reduce file size with a format-aware local compressor.
PDFs, images, and Office files store data differently, so useful compression starts by choosing the right method for the actual format rather than wrapping every file in a ZIP.
Choose one practical target
Use Smallest file for strict upload limits, Balanced for ordinary sharing, or Higher quality when visual detail matters. The compressor keeps the file on this device and reports when the original is already smaller than any safe result.
Review the format-specific risks
Strong PDF compression may flatten pages, image compression changes pixels, and Office compression focuses on embedded images plus package structure. Keep the original and open the result in the application that normally handles it.
