Frequently Asked Questions
Everything you need to know about our privacy architecture
Why is client-side processing safer than cloud-based PDF tools?
When you upload a PDF to a cloud service, your confidential financial reports, medical records, or legal contracts are transmitted over the internet to a third-party server. SnapPDF executes 100% locally inside your web browser sandbox using WebAssembly, ensuring no external entity ever sees or stores your data.
How can SnapPDF be completely free without ads or watermarks?
Traditional PDF websites incur heavy server compute costs to render and modify files remotely. Because SnapPDF utilizes your device’s own CPU and browser RAM, our operational hosting costs are virtually zero, allowing us to offer industrial-grade PDF tools with no subscriptions or artificial limitations.
Does SnapPDF support large PDF files with hundreds of pages?
Yes. Since rendering occurs client-side, SnapPDF is bounded only by your computer’s RAM. You can comfortably annotate, rotate, and search through 500+ page documents with zero upload lag.
Are annotations exported in industry-standard PDF format?
Yes. SnapPDF compiles all highlights, drawings, stamps, and signatures directly into ISO 32000-1 PDF vector streams using pdf-lib, making them fully viewable and editable across Adobe Acrobat, Apple Preview, and Google Chrome.
