Frequently Asked Questions
How do these PDF tools work without uploading files?
We use WebAssembly (Wasm) — a technology that runs near-native code directly in your browser. This means full PDF processing happens on your device with zero network transfer.
Are cloud-based PDF tools a privacy risk?
Yes. When you upload a PDF to a cloud service, that file is stored on their servers. For confidential documents — contracts, financial records, medical files — local processing is the only safe option.
Which tools are available?
Compress PDF, Merge PDF, Split PDF, PDF to Word, and Remove PDF Password — all running locally.
Is this free?
