Free PDF Scanner, Maker & Merger
ul0's PDF tool turns your phone or laptop camera into a document scanner with automatic edge detection and auto-crop, just like premium scanner apps. Convert photos and images (JPG, PNG) into a clean multi-page PDF, merge several PDFs into one file, reorder or rotate pages, apply a grayscale or black-and-white scan filter, and rename your file before downloading. Everything happens locally in your browser, so your documents never leave your device.
Is this PDF scanner really free?
Yes. There's no signup, no watermark, and no limits. It's 100% free.
Are my documents uploaded to a server?
No. Scanning, conversion and merging all run on your device for full privacy.
How does auto-crop work?
We detect the largest document shape in the frame and straighten it automatically. If detection isn't possible, the full image is used.
