Scan documents
Photograph or pick photos of pages, auto-flatten the 4 corners into a “scan”, then merge into a PDF — right on your device, images never leave your machine.
Images are processed on your device — no file is uploaded to any server
Scan Documents turns your phone into a pocket scanner: just photograph the pages of a document, and the tool automatically detects the 4 corners of the sheet, corrects the perspective and enhances sharpness to produce a clean, straightened scan, then merges the pages into a single PDF file.
It offers Color / Enhance / Black & white modes suited to contracts, application forms, and invoices. Image processing uses a bundled OpenCV that runs 100% on your machine — your document images never leave your device and it works even without an internet connection.
How to scan documents to PDF on your device
- 1Take or choose photos
Photograph the document pages, or choose existing images (JPG/PNG/WebP). Select several images for a multi-page document.
- 2Flatten & adjust corners
The tool automatically detects the 4 corners of the sheet; drag the points to fine-tune the fit, then choose an image style (Color / Enhance / Black & white).
- 3Create PDF & download
Click Create PDF to flatten each page, merge them into a single PDF file, and download it to your device.
Frequently asked questions
Are my images uploaded to a server?
No. All processing (corner detection, flattening, PDF creation) runs right in your browser using a bundled OpenCV. Everything runs right in your browser — your files are never uploaded to any server, keeping them completely private.
Does it work without an internet connection?
Yes. The image-processing library is bundled locally and runs 100% on your machine, with no network connection required.
Is the text in this scanned PDF searchable (OCR)?
Not yet. The tool creates an image-based PDF (like a scan) without a searchable text layer — text recognition (OCR) is out of scope for this tool.
