Frequently Asked Questions

Are my files being sent?

No. Everything happens in your browser.

Is there any loss of quality?

In advanced compression, pages are rasterized and images may lose sharpness as the level increases.

Maximum size?

The limit depends on your device and browser.

We process in the browser and we do not store the entered data.

Compress your documents without leaving the browser. Your files are not sent to servers: all processing occurs locally on your device, preserving privacy and security.

Simple compression rewrites the document to remove overhead and metadata. Meanwhile, advanced compression converts the pages into images, allowing you to reduce size by adjusting resolution and quality. Choose the level that balances size and readability for your use case.

Tip: documents with many photos tend to experience significant quality loss at higher levels. Text-only documents tend to have smaller gains. Always check the result before sharing.
