How to scan documents to PDF on Android

A paper form on your desk and no scanner in the house is a common bind. Your phone camera can stand in for the scanner, and Sigvo turns the photo into a clean PDF you can sign right away.

The short answer

Open the scanner in Sigvo, photograph the page, confirm the auto-detected edges, and export a clean PDF. Everything runs on the phone, offline, and the scan opens in the editor so you can sign it.

Scan a single page

1. Open the scanner in Sigvo and point the camera at the page.
2. Sigvo finds the edges, straightens the image, and sharpens the text.
3. Confirm the crop, or drag the four corners to adjust it.
4. Export the PDF, or sign it first.

Choose a colour, grayscale, or high-contrast look depending on the document. High contrast is best for plain text; colour keeps stamps and logos readable.

Batch-scan a whole stack

When you have a pile of pages, batch mode saves the most time.

1. Turn on batch mode.
2. Hold each page in the frame and let the camera catch it hands-free, or use the shutter.
3. Sigvo stamps your signature, the date, and a rising number on each page.
4. Export the whole stack as one signed PDF.

This is the fast way to sign a set of contracts or forms without repeating the same steps on every page.

Sign the scan

A scanned page opens in the same editor as any PDF. Add a signature, fill a field, or stamp a date, then share the finished file. There is no need for a separate signing app.

Get a clean scan

• Lay the page on a flat, plain surface with even light.
• Fill the frame with the page so the edges are easy to detect.
• Avoid harsh shadows across the text.
• For a glossy page, tilt slightly to dodge glare.

Your scans stay on the phone

Camera captures are cropped and enhanced on the device, then discarded. Nothing is uploaded, so a scanned ID or contract stays with you. Sigvo needs the camera permission only for scanning and batch mode.
