How to Scan Documents With Your Phone Into a PDF
You don't need a scanner to digitise paperwork. A modern phone camera can produce perfectly readable scans of forms, receipts, certificates and contracts, if you set the shot up properly. This guide covers how to capture good pages and how to turn them into a single clean PDF.
Check what your phone already does
Many phones have a built-in document scanner that straightens and crops pages automatically. On an iPhone it's in the Notes app (Scan Documents); on many Android phones the Google Drive app has a Scan option. If you only need one quick scan, those are the fastest route. The steps below help with any method, and they matter most when you're using the camera directly.
Setting up the shot
- Light it evenly. Daylight near a window is ideal. A single bright lamp creates glare and hard shadows. Avoid your own shadow falling across the page.
- Use a plain, darker surface. A dark desk or a sheet of coloured paper under the page makes its edges easy to see, which helps automatic cropping.
- Flatten the page. Creases and curved book pages cause distortion. Press folded pages flat, or weigh the corners down.
- Hold the phone parallel to the page. Tilting it makes the far side look smaller and the text harder to read. Directly overhead is best.
- Fill the frame, but keep all four corners in view. Don't cut off the edges of the page.
- Steady the phone and let it focus. Tap the text to focus, hold still, then capture. Blurry text can't be fixed later.
- Turn off the flash. It creates a bright hotspot on glossy paper.
Turning the pages into one PDF with Quikbench
- Open Scan to PDF in your phone's browser and allow camera access.
- Capture each page. Retake any that came out blurry.
- Create the PDF, which combines the pages in the order you captured them.
The camera and the pages stay in your browser; nothing is uploaded. If you already have photos in your gallery, Image to PDF builds a PDF from them instead.
Cleaning up the result
- Wrong order, or an upside-down page? Rearrange PDF lets you reorder, rotate and delete pages.
- File too big to email? Phone photos are large. Compress PDF explains how to shrink it, and shrinking the pictures first with the Image Compressor usually saves the most.
- Need to search or copy the text? A scan is a set of pictures. OCR PDF adds a searchable text layer, including for Hindi and many other languages.
- Page looks soft? If a scan came out low-resolution and you can't redo it, see our guide to sharpening a blurry scanned PDF.
Common problems
- Shadows across the page: move to a window, or hold a sheet of paper to bounce light into the shadow.
- Glare on glossy paper: tilt the page slightly or change the angle of the light, and don't use the flash.
- The camera won't start: check that you allowed camera access for the site, close other apps that might be using the camera, and try a current browser.
- The text is hard to read: move closer, make sure the page fills the frame, and retake in better light.
A note on sensitive documents
Passports, ID cards and bank papers are worth protecting. Browser-based tools like Scan to PDF keep your pages on your device, and you can add a password to the finished PDF with Protect PDF (which processes the file on our server and doesn't store it). Delete scans you no longer need from your phone.
