Most PDF compression tools require you to upload your files to remote servers, creating privacy risks for sensitive documents. CompressMyPDF is different: it uses WebAssembly technology to run Ghostscript directly in your browser, so your files never leave your device.
Whether you are compressing confidential business reports, legal contracts, or personal documents, your data remains 100% private. There is no server processing, no temporary storage, and no risk of data breaches.
With support for multiple compression presets, from screen-optimized (72 DPI) to prepress quality (300 DPI), you get full control over the balance between file size and visual quality. The tool works offline after the initial page load, making it perfect for use anywhere.
