Why use Mergevanta to scan documents to PDF
Straightens tilted pages
Drag four corners, or tap Detect edges, and the page is flattened with perspective correction — no more slanted, trapezoid scans.
Looks that read well
Black & white gives crisp text and removes shadows; Enhance whitens the paper and lifts contrast. Grayscale and Original are there too.
Sensible file sizes
Pages are saved at up to 200 dpi, and black-and-white pages are stored as 1-bit images, so text stays sharp while the PDF stays small.
Private by design
The camera and your photos are used only in this tab. Nothing is uploaded, and the camera switches off as soon as you're done.
