How to: PDF Scanner
- Select photos of your pages (or take them with your phone camera).
- Check the detected edges and drag corners if needed.
- Choose enhancement and download the PDF.
A phone camera is a perfectly good scanner if the photo is cropped, straightened and cleaned up. FreePDF detects the page edges, corrects the perspective, evens out shadows and turns your photos into a multi-page PDF – no app install, no account and no upload, which matters for IDs, contracts and medical papers.
Common uses
- Scan signed contracts, receipts or ID documents.
- Digitise handwritten notes or homework.
- Create a PDF of a form to email back.
- Archive old letters and certificates.
Tips for best results
- Photograph the page on a dark, contrasting surface for best edge detection.
- Avoid harsh shadows; use daylight when possible.
- Drag the round handles to correct any corner the detector missed.

Frequently asked questions
How does auto-crop work?
The page is found as the largest bright area in the photo, its four corners are located and the image is straightened with a true perspective transform, so a photo taken at an angle looks like a flat scan.
Which mode is best for text?
'Black & white (photocopy)' gives crisp, small files for text documents; 'Colour' keeps stamps and signatures in colour with a whiter background.
Can I use my phone camera directly?
Yes – on phones, the file picker offers the camera. Or use Camera to PDF for live capture.
Is it really free?
Yes, no watermark and no limits.
