Knowledge Center & Overview
Topic Overview
Portable Document Format (PDF) is the universal file format for sharing document layouts across systems. ToolsAtZero's PDF Suite provides clean, secure, client-side PDF modification. By executing tasks directly in-browser using WebAssembly and memory buffers, your confidential document information never reaches external cloud servers, preventing common cloud-storage leaks.

Q: Are my PDF documents uploaded to your servers?

Q: Is there a file size limit for merging or splitting?
