Document Scanner
Upload one or more photos of a document (form, certificate, letters) and this tool combines them into a single PDF. You can rotate pages, fit them to A4, and download a clean, shareable PDF. It does not perform automatic edge detection or perspective correction. All processing is done locally — your documents never leave your device.
Your files never leave your device. All processing happens on your device. No uploads, ever.
