Our tool optimizes PDF structure, removes duplicate data, and compresses embedded images. All processing happens in your browser, ensuring your files stay private.

The "Low" compression setting maintains nearly identical quality. Higher compression levels trade some visual quality for smaller file sizes. Text remains sharp at all levels.

There's no strict limit, but very large files (over 100MB) may be slower to process. Since everything runs in your browser, performance depends on your device's capabilities.
