Introduction: Scan to PDF Online Free
Your phone is already a scanner — you just need the right tool. The free Scan to PDF from Trencada turns your phone camera or webcam into a document scanner right in your browser: capture pages one by one, arrange them in order, pick color, grayscale, or black & white, and download everything as a single PDF. No app to install, no account, no uploads — every page is processed on your device.
How to Scan Pages into a PDF
- Tap Start Camera and allow camera access (or choose Add Photos Instead to use existing pictures).
- Point at each document page and tap the shutter to capture it. Use Switch camera to flip between front and rear cameras.
- Reorder pages with the arrow buttons, delete mistakes with ×, and add more photos anytime.
- Choose a look (color, grayscale, or black & white) and a page size (fit to photo, A4, or US Letter).
- Tap Build PDF, then download your scanned document.

Why Scan with Trencada?
Most scan-to-PDF tools force you through their mobile app, an account, or an upload to their servers. Trencada works in any modern browser — phone, tablet, or desktop — with zero installs and zero uploads, so sensitive documents stay yours. After scanning, you can compress the scanned PDF to share it more easily. If you already have pictures saved on your device, you can also convert images to PDF directly without the camera.
Frequently Asked Questions (FAQ)

What if my device has no camera? Choose Add Photos Instead to build a PDF from pictures already on your device, or use your desktop webcam in the browser.
