Frequently Asked Questions on Architecture & Comparison

Why is Document Reader faster than Adobe Acrobat Pro and online converters?

Online converters like Smallpdf and iLovePDF require uploading your entire multi-megabyte file across the internet to a remote server, queuing it for compute, and downloading the result. Document Reader processes everything directly inside your browser memory with WebAssembly, executing tasks in under 0.02 seconds with 0ms upload delay.

How can Document Reader offer 100% free tools without adding watermarks?

Because all document computations run on your own device hardware, our server bandwidth and compute costs are virtually zero. This allows us to offer all PDF editing, merging, converting, and signing tools 100% free forever without forcing subscriptions or watermarking your files.

Is Document Reader safe for confidential medical and legal files?

Yes, 100%. Files never leave your local device memory. There is zero risk of server data breaches, accidental cloud caching, or third-party tracking, fully satisfying HIPAA, GDPR, and eIDAS compliance standards.
