Built for privacy, clarity, and control

Why we created OnDevicePDF

At some point, most of us have uploaded a PDF to an online tool without really knowing what happens next.

Where is the file stored? Is it deleted immediately? Is a copy kept? Who can access it? These questions usually go unanswered - especially when the document contains contracts, IDs, financial records, or internal work.

The uncomfortable truth is that many cloud-based tools ask for trust without offering visibility. You upload sensitive files and simply hope they’re handled responsibly.

We didn’t want to keep making that trade-off. Editing a PDF shouldn’t mean giving up control over where your data lives or how long it exists.

So we built OnDevicePDF around a simple idea: local-first processing by default, with explicit disclosure when advanced workflows need temporary backend support.

Most tools run locally in your browser. No accounts. For advanced PDF Editor operations, temporary backend processing is used with auto-delete controls. You stay informed and in control from start to finish.

Privacy isn’t about hiding data. It’s about knowing exactly where it is.

How OnDevicePDF works

Most tools run entirely in your browser. Merging, splitting, stamping, converting, and exporting usually happen locally using your device’s compute and memory.

Advanced PDF Editor operations may use secure temporary backend jobs for OCR and complex edits. Sessions are time-limited and can be removed immediately.

Our promise

• Most tools process PDFs on your device
• Advanced editor flows use secure temporary backend processing with auto-delete
• No accounts, no tracking of document contents
• Fast, offline-capable tools
• Simple workflows without unnecessary complexity
