Do online PDF tools upload my files?
Many do — they send your file to a server to process it. CyvoDocOps processes supported operations locally in your browser, so for those tools the file is not uploaded.
Are online PDF tools safe?
Most online PDF tools upload your document to a server to process it. CyvoDocOps takes a local-first approach: for supported operations, your file is processed in your own browser and is not uploaded — so the document does not leave your device for those tools.

Frequently asked questions
Is local processing more private?
Yes. When a document is processed on your own device it is not sent to a third-party server, which reduces exposure. Always check each tool's note for whether it runs locally.
Which operations run locally?
All 39 operations marked Available or Best-effort on the Tools page run locally in your browser. The nine mobile-only operations are labelled separately.
