Compress PDF

Yes, RamenTask processes all files directly in your browser. Your sensitive data never leaves your device and is never uploaded to a server.

If a PDF is already optimized or contains mostly text without high-resolution images, the compression margin is smaller.

The 'Lossless' preset maintains original quality. 'Balanced' and 'Max' levels reduce image resolution to achieve significant size reduction.

The limit depends on your browser's memory (RAM). Most standard PDFs up to 100MB should work without issues.

Since the compression happens entirely within your browser's memory using WebAssembly, your file is never exposed to the internet or stored on a disk that isn't yours.

Yes, our 'Lossless' and 'Balanced' modes use advanced optimization algorithms that target redundant data and over-sized images while maintaining professional-grade clarity.
