About the PDF Scanner
Our free online PDF scanner turns your device's camera into a portable document scanner. Capture documents, whiteboards, receipts, or notes using your camera, or upload existing images, and combine them into a single PDF document right in your browser. The built-in image enhancement feature applies auto-level adjustments to improve contrast and readability, making your scanned documents look crisp and professional.
Unlike dedicated scanner hardware or mobile apps that require installing software, our PDF scanner works entirely in your browser with no installations needed. You can capture multiple pages, preview them in a grid, and remove or reorder pages before creating the final PDF. The tool automatically scales large images to optimal dimensions for PDF output, balancing quality with file size.
All processing happens in your browser — your images and documents never leave your device. This makes it ideal for scanning sensitive documents like ID cards, contracts, or personal notes that should not be uploaded to third-party servers.
