Scan to PDF
Turn any physical document into a clean PDF using just your device camera. No app to install, no scanner hardware to buy, no account to create. Capture receipts for expense reports, digitize handwritten notes, photograph whiteboards after a meeting, or save signed forms — all directly to a polished multi-page PDF. Every image stays on your device and is never uploaded anywhere.

About this tool
The Scan to PDF tool turns your phone or laptop camera into a portable document scanner. Each photo you capture is automatically fitted to A4 page dimensions while preserving the original aspect ratio, so your scans look clean and consistent. You can capture as many pages as you need, preview them before creating the PDF, and re-take any page that came out blurry or poorly lit. Because the entire process runs locally in your browser, sensitive documents — like contracts, IDs, or medical records — are never transmitted over the internet. This makes it a genuinely private alternative to scanner apps that upload your images to cloud servers.
How to use
- 1
Allow camera access
When you open the tool, your browser will ask for permission to use the camera. Tap 'Allow' to enable the live viewfinder. This permission is temporary and only lasts while you're on the page — no permanent access is granted. If you accidentally denied access, you can reset the permission in your browser settings.

Position your document
Place your document on a flat, well-lit surface. Natural daylight works best and avoids the shadows that overhead lamps can cast. Hold your device steady and align the document within the on-screen guides. For best results, make sure all four corners of the document are visible in the frame.

Capture each page
Tap the capture button to take a photo of each page. You can capture as many pages as you need — there's no limit. Flip between front and rear cameras using the switch button if you want to scan something on a desk while using the rear camera, or capture a whiteboard with the front-facing camera.

Review and re-capture
After capturing, scroll through the thumbnail strip to review each page. If a page is blurry, poorly lit, or crooked, delete it and re-capture. It's faster to re-take a bad photo now than to redo the entire PDF later. The thumbnails show exactly what will appear in the final PDF.

Create and download your PDF
When you're satisfied with all pages, tap 'Create PDF.' The tool assembles all captured images into a single PDF, fitting each one to an A4 page size while preserving the aspect ratio so nothing gets stretched or cropped. Download the PDF immediately — it never leaves your device.
Common use cases
- Scan receipts and invoices for expense reports and accounting.
- Digitize handwritten notes, meeting whiteboards, and brainstorming sessions.
- Capture signed contracts and forms while on the go.
- Scan IDs, business cards, and membership cards for your records.
- Photograph physical photos, certificates, and important documents for backup.
Tips & troubleshooting
- •Use natural daylight whenever possible — it produces the clearest, most evenly lit scans with accurate colors.
- •Place dark-colored documents on a light background (like a sheet of white paper) to make edges clearly visible.
- •Hold your device parallel to the document to avoid perspective distortion. A slight overhead angle works better than shooting from the side.
- •For multi-page documents, capture all pages in one session to keep them organized in the correct sequence.
- •If you need a specific page size other than A4 (like US Letter), use the Crop tool after scanning to trim the margins to your exact dimensions.
Frequently asked questions
Are my camera images stored or uploaded anywhere?
No. Everything stays in your browser's memory. Images are captured, displayed, and assembled into the PDF entirely on your device. No data is ever transmitted to a server — not even temporarily. You can verify this by disconnecting from the internet after the page loads; the tool will continue to work.
Can I switch between front and rear cameras?
Yes. Tap the flip button in the camera interface to switch between front and rear cameras. Use the rear camera for scanning documents on a desk, and the front camera for capturing whiteboards or yourself signing a document.
What page size is used for the output PDF?
Images are fitted to A4 pages (210 × 297 mm) by default, which is the standard for most documents worldwide. Each captured image maintains its original aspect ratio, so it won't be stretched or distorted — empty space around the image appears as white margin.
Does the tool work on desktop computers?
Yes. If your desktop or laptop has a webcam, the tool works exactly the same way. For scanning physical documents on a desk, a phone or tablet with a rear camera usually produces better results, but the tool is fully functional on any device with a camera.
What if my scans come out blurry or dark?
Good lighting is the key. Natural daylight produces the cleanest results. Avoid casting shadows from your body or phone onto the document. Hold the device steady and let the camera auto-focus before capturing. If results are still poor, try placing the document near a window or using a desk lamp from the side to reduce glare.
