Common Interrogatories

Expert Knowledge Base Resolved

Why is a web app better than a native mobile app for compressing PDF?

Native apps often require invasive permissions, take up storage space, and may track your data. A modern web app like PdfXpo requires zero installation, works instantly in your browser, and uses local WASM technology to ensure your files never leave your device. It offers the speed and privacy of an offline app with the convenience of a website.

What makes PdfXpo the best app for PDF compression?

PdfXpo stands out due to its 'privacy-first' architecture. We don't use cloud-based processing for your documents. Instead, the compression happens locally on your CPU via your browser. This combined with no daily limits, no watermarks, and high-fidelity output makes it the top choice for professionals and casual users alike.

Does the best app to compress PDF require a subscription or account?

No. Unlike many competitors that hide their best features behind a paywall or login screen, PdfXpo is completely free and open. You can compress as many files as you want without creating an account or providing an email address.

Can I use this 'web app' on both iPhone and Android?

Yes. PdfXpo is built using responsive web technology. It functions perfectly as an app in Safari on iOS, Chrome on Android, and any desktop browser. You can even 'Add to Home Screen' to use it just like a native mobile application.
