Scan Documents to PDF
Use your phone camera to capture pages and turn them into one PDF. 100% in your browser — photos never leave your device.
Scan with your camera
Mobile-first — uses your phone's back camera. Or upload existing photos instead.
Hold the phone parallel to the document. Good light, dark background helps.
Your file is ready
Processed entirely in your browser — the file never left your device.
Three steps, one PDF
Open the camera, capture each page, make the PDF.
Open the camera
Tap Open camera — the browser asks once for permission. Back camera is used by default.
Capture each page
Frame the document, tap the shutter. Reorder or delete thumbnails as needed.
Make & download
Choose A4 / Letter / Fit, tap Make PDF. The file is built locally and saved to your device.
What is "scan to PDF"?
Scan-to-PDF means using your phone (or laptop webcam) to photograph a physical document and bundle the resulting images into a single PDF. It is the modern replacement for a dedicated flat-bed scanner: you already carry a camera in your pocket, and PDF readers exist on every platform. The result is one tidy file you can email, upload to a portal, or archive in cloud storage — instead of three blurry photos attached to a chat thread.
For most everyday needs — receipts, IDs, signed pages, whiteboard notes — the camera in a modern phone produces an image sharp enough for any business workflow. Wrapping those frames as a PDF gives you consistent page sizes, a stable file format that prints correctly, and a single attachment that opens the same way on every device.
How camera scan works in your browser
When you tap "Open camera", the page asks your browser for camera
access through the standard getUserMedia
API. The browser shows the permission prompt; after you allow it, the
live video stream is rendered inside a <video>
element on the page. The stream lives entirely on your device — it is
not sent anywhere.
Each tap of the shutter button draws the current video frame onto an
offscreen <canvas> and exports it as a JPEG with
canvas.toBlob. The captured JPEG is added to an
in-memory list. When you tap "Make PDF",
pdf-lib
creates the PDF document, embeds each captured JPEG, and saves the
result as a Blob your browser downloads. No part of the flow involves
a server — you can confirm by running the tool with the network
disconnected after the first page load.
Common use cases
- Expense receipts. Snap each receipt on the trip, end the day with one chronological PDF for accounts. No more flooding the expense system with 12 attachments.
- ID and proof-of-address. Capture an ID card and a utility bill, bundle them into one PDF for KYC uploads — much friendlier than separate JPGs.
- Business cards. Photograph the cards you collected at an event, save them as one searchable PDF to attach to the follow-up email.
- Whiteboards and lecture notes. After a meeting or a class, photograph each board section, build one PDF, drop it in the shared folder before anyone erases.
- Handwritten notes and forms. Capture each page of a paper form, send it to the recipient as a PDF without leaving your phone.
Privacy & security
Document photos — IDs, receipts, contracts, medical letters — are exactly the kind of file you do not want on a stranger's server. Dedicated scanner apps usually upload to their cloud and ask you to trust their retention policy. imisspdf builds the PDF inside your browser with pdf-lib. The camera stream stays on your device, no photo or PDF is uploaded, no account is required. See our iLovePDF privacy review or the imisspdf vs iLovePDF comparison for the deeper architectural picture.
Frequently asked questions
No. The camera frames are captured directly into your browser, the PDF is built locally with pdf-lib, and the result is downloaded straight from your device. There is no upload, no temporary server-side file, no logs. You can verify this by running the tool with your network disconnected after the first page load — the camera capture and PDF build still work.
Three common reasons. First, browsers require HTTPS for camera access — http://imisspdf.com would be blocked but https://imisspdf.com works, and so does localhost during development. Second, the first time you tap the camera button the browser asks for permission; if you denied it, you have to re-enable camera access for the site in your browser settings. Third, some browsers (older Safari versions on iOS, in-app browsers like Facebook or Instagram in-app web views) limit getUserMedia. If the camera will not open, use the "Upload photos instead" fallback.
Practical limit is your device memory, not a server quota. On a typical phone you can comfortably capture 30–50 pages before memory pressure becomes noticeable. For very long documents, capture in two batches and merge the resulting PDFs with the Merge PDF tool.
Not in this version. v0.1 keeps the captured frame as-is — what you point the camera at is what the PDF gets. To compensate, hold the phone parallel to the document, fill most of the frame, and use a dark background so the document edges stand out. Automatic perspective correction (similar to dedicated scanner apps) is planned for v0.2.
Adobe Scan and similar apps do automatic edge detection, perspective correction, and contrast cleanup, then upload the result to Adobe Document Cloud. imisspdf scan-pdf is simpler and stays in the browser — no app to install, no account, no upload. For receipts, IDs, business cards and quick whiteboard captures the in-browser flow is usually faster end-to-end. For a 50-page contract where you need crisp auto-cropping, a dedicated scanner app is still better.
Tips for best results
- Light from above, not behind. Diffuse overhead light reduces glare and shadows. A window in front of you works; a window behind you backlights the page and looks washed out.
- Hold the phone parallel to the document. A perpendicular angle keeps the page rectangular in the frame. v0.1 does not auto-correct perspective, so straight-on framing translates directly to a clean PDF page.
- Fill the frame. Get the document edges close to the edges of the preview. Extra background just shrinks the usable area of the PDF page.
- Dark contrasting background. Place white paper on a dark surface (or vice versa). High contrast at the document edges makes future auto-crop features more reliable.
- Hold steady, tap softly. Most blurry pages come from camera shake at the moment of tapping. Brace your elbows or rest the phone on a surface for the shutter tap.
Honest expectations. Best scan results require good lighting and a steady hand. There is no automatic perspective correction in v0.1 — point the camera straight at the document for now. Auto-crop is planned for v0.2. Camera access requires HTTPS, which imisspdf.com provides; local development on localhost also works.
