PDF tools with no upload
Do the PDF jobs you already need — without sending documents to someone else’s server.
Most “free online PDF” sites work the same way: you upload a file, their server processes it, and they promise to delete it later. That model is convenient for them. It is a privacy risk for contracts, IDs, tax forms, and work docs.
GroundPDF is different by architecture. Tools run in your browser with WebAssembly (Rust). Your PDF stays in device memory. There is no file upload API for documents.
What you can do without uploading
- Merge PDF — combine files in any order
- Compress PDF — shrink size locally
- Split PDF — extract ranges or every page
- Rotate, reorder, delete pages
- Sign, watermark, edit
- JPG to PDF, PDF to Word, OCR
How to verify nothing was uploaded
- Open any GroundPDF tool.
- Open DevTools → Network.
- Drop a PDF and run the tool.
- You should not see your document POSTed to a server. (Some optional engines like OCR/ffmpeg load from a CDN only when you use those tools — still not “your PDF to our bucket.”)
FAQs
Do no-upload PDF tools really work?
Yes. Modern browsers can run serious PDF and image code via WebAssembly. GroundPDF ships Rust-compiled Wasm so merge, compress, and more run on your machine.
Is no upload the same as encrypted upload?
No. Encrypted upload still sends a copy to a server. No upload means the file never leaves your device.
Is GroundPDF free?
Yes. Free tools, no account required for core PDF and image jobs.
Can I use this for sensitive documents?
That is the point. Keep NDAs, medical, and tax PDFs on the ground. You still control the device and browser extensions you trust.
