Scan to PDF Online — Capture Documents with Your Phone Camera Free
Turn your smartphone into a document scanner and convert photos directly to a PDF — no app download required. Our free Scan to PDF tool lets you capture document pages with your phone's rear camera and build a clean multi-page PDF in seconds. Use it directly on your phone, or scan from your phone and receive the images on your desktop browser using the QR code session feature.
Everything runs in your browser using jsPDF. Photos you take are never uploaded to any server — they stay on your device throughout the entire conversion process.
How to Scan a Document to PDF — Step by Step
- Choose your workflow — Use the Camera / Upload tab to scan directly on your current device, or use the Scan from Phone (QR) tab to send photos from your phone to your desktop browser.
- Capture your pages — Tap Take Photo to open your rear camera directly (on mobile) or browse for existing image files. Add as many pages as needed.
- Reorder if needed — Drag page thumbnails to arrange them in the correct order. Click ✕ to remove any unwanted scan.
- Choose PDF options — Select page size (Fit to Image, A4, or Letter), orientation, image enhancement, margin, and quality.
- Click "Convert Scans to PDF" — The PDF is assembled and downloads automatically.
Two Scanning Workflows
📷 Camera / Upload (Same Device)
Open this page on your phone and tap Take Photo to activate the rear camera directly — no app required. On mobile browsers, the camera opens automatically in document-capture mode. On desktop, the same button opens a file picker for existing images. You can add multiple photos in one session by tapping the button repeatedly.
📱 Scan from Phone via QR Code (Cross-Device)
Working at your desktop but want to scan with your phone? Switch to the Scan from Phone tab — a QR code and session code appear immediately. Scan the QR code with your phone, take photos in the mobile scanner that opens, and the images appear automatically in your desktop browser within seconds. No login, no app, no cloud service required — images are transferred via your browser's local storage across tabs.
Five Image Enhancement Modes
Original
No processing applied. Best for photos already taken in good lighting with a document scanner app or under controlled conditions.
↑ Contrast
Boosts the difference between light and dark areas by 40%. Makes text pop against the background in documents photographed under uneven lighting.
⬛ Grayscale
Converts the image to black and white tones. Reduces file size significantly and gives scans a clean, professional document appearance — ideal for text-heavy pages.
🖨 Black & White
Applies a hard threshold: pixels above 50% brightness become white, below become black. Creates crisp, high-contrast scans similar to photocopier output. Best for printed text with minimal background noise.
🔍 Sharpen
Applies a convolution sharpening kernel to improve edge definition. Helps recover clarity from slightly blurry photos taken without a tripod.
Key Features
- Direct camera access on mobile: The Take Photo button opens the rear camera instantly — no app installation needed.
- QR cross-device workflow: Scan the QR code on your phone, capture photos, and receive them on your desktop browser automatically via localStorage session polling.
- Multi-page scanning: Add as many pages as needed — each becomes one page in the PDF.
- Drag-to-reorder: Arrange pages in the correct order by dragging thumbnails before converting.
- Five enhancement modes: Original, Contrast Boost, Grayscale, Black & White, and Sharpen — applied at export time.
- Three page sizes: Fit to Image, A4, and Letter — with portrait and landscape options and a margin slider.
- Quality slider: Control JPEG compression to balance file size and scan clarity.
- 100% browser-based: jsPDF assembles the PDF locally — no images are sent to any server.
- No watermarks: The output contains only your scanned pages — nothing added.

Frequently Asked Questions
Is this Scan to PDF tool completely free?
Yes. No subscription, no usage limits, no hidden fees. Scan and convert as many documents as you need at no cost.
Are my photos uploaded to a server?
No. Photos captured on the same device are processed entirely in your browser using jsPDF — no data is sent anywhere. The QR cross-device feature transfers images between your phone and desktop using your browser's localStorage — no server is involved.
Does the camera button work on iPhone and Android?
Yes. On both iOS Safari and Android Chrome, the Take Photo button activates the rear camera directly. Some browsers may present a choice between camera and file picker — select Camera for live capture.
How does the QR code cross-device feature work?
Scanning the QR code opens the same page on your phone with a special session parameter. Photos you take there are stored in your browser's localStorage under a session key. Your desktop browser polls localStorage every 1.5 seconds and picks up new photos automatically — no internet relay, no cloud service.
Which enhancement mode should I use for text documents?
For printed text on white paper, Black & White gives the cleanest result — crisp black text with no grey background noise. For handwritten notes or documents with colour elements, Grayscale or Contrast Boost work better. Use Original for photos with colour content you want to preserve.
Can I add more photos after the first batch?
Yes. Tap Take Photo or Upload Images as many times as needed — new images are added to the end of the list. Reorder them by dragging thumbnails before converting.
Does the output PDF have a watermark?
No. The output contains only your scanned page images — no watermarks, no branding, no added pages.
What page size should I choose for printing?
Choose A4 for standard international printing or Letter for US paper. Use Fit to Image if you want the PDF page to exactly match the photo dimensions with no borders — best for digital sharing where print layout is not a concern.

Scanning documents to PDF should be as simple as pointing your phone at a page.
