Scan documents to PDF — free

Open this tool on your phone, tap Start Camera, allow camera access, frame the document and tap Capture for each page. Pages are stacked into a multi-page PDF that you can reorder by dragging. When you are done, tap Build PDF and the file downloads to your phone. No scanner app to install.

Yes — getUserMedia (the camera API) is supported on iOS Safari 14+ and Android Chrome / Firefox. The tool requests the rear (environment) camera by default at the highest resolution your device supports, which is typically 1920×1080 or higher on modern phones.

Yes. The "From gallery" button lets you pick existing images from your camera roll or files app. You can mix camera captures and gallery picks in the same PDF — useful when you want to add a scanned ID to a photographed contract.

Choose A4 for international correspondence and Letter for US documents — both produce print-ready PDFs at the standard paper size with the photo centered. "Fit to image" sizes each PDF page to its source photo, producing a smaller file with no white margins (good for purely digital sharing).

No — Scan to PDF produces an image-only PDF (the photo embedded inside a PDF wrapper). To make the text searchable and selectable, run the output through our PDF to Text tool (extracts text) or Image to Searchable PDF (adds a hidden text layer).

No. Camera frames stay on your device; PDF assembly runs in your browser via pdf-lib. This is critical for sensitive scans like passports, bank statements, contracts and medical records where uploading to a third-party service is a non-starter.

Use bright, even lighting — daylight near a window is best. Hold the phone parallel to the page (not at an angle) to avoid keystone distortion. Capture at full quality (slider at 90%+) and pick "Fit to image" if you plan to print, so the page is not downscaled to A4.

Yes. No subscription, no per-page fee, no daily cap. Unlike scanner apps that paywall multi-page exports or add watermarks, our tool is free and unlimited.
