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.

FAQ

Scan to PDF questions

No. Scan to PDF works in the browser on iPhone, iPad, Android phones and computers with a webcam. Allow camera access when your browser asks.

No. The photos are processed and the PDF is made on your device. Nothing is sent to Mergevanta's server, and the camera turns off when you close it or leave the page.

Allow the camera in your browser's site settings and try again, or tap Open camera app to take the photos with your phone's own camera — they're added the same way. You can also choose photos you already have.

Pages are saved at up to 200 dpi, sharp enough to read and print small text, and never beyond the detail your photo actually has. A closer, well-lit photo gives a crisper page.

Yes. Open the finished file in OCR PDF to add an invisible text layer, so you can search, select and copy the words.

Tap the page and press Rotate. Each tap turns it 90° clockwise, and its corners turn with it.
