Turn paper into a clean PDF

A phone in your pocket is a capable document scanner once two things are right: even light on the page and a shot taken square to the paper. The guides below cover each job separately, from a single receipt to a forty-page stack and a passport.

Which page matches your paper?

Zuzana is clearing her late father's desk: a drawer of receipts, a passport to renew, a thirty-page house contract, and an iPhone full of HEIC photos she shot last week. Four piles, four different pages, one shared rule about light and angle. Find your pile below.

Two tools do the assembly work behind these guides. Images to PDF stacks JPG and PNG photos into one file without resampling, so the camera's pixels are the PDF's pixels. HEIC to PDF takes each iPhone photo's primary still image straight to PDF with no conversion step in between. Both check the finished file before download, and a scan that arrives crooked can be straightened afterwards with the rotate tool.

Scanning mistakes that force a reshoot

Your own shadow on the page. Standing between the lamp and the paper films a grey band across the text. Light the sheet from the side and check the first shot before shooting forty more.

Flash left on. A flash blows out the centre of the page and leaves the edges dark, which no later step evens out. Move the paper toward a window instead.

Retakes spliced into the middle. Reordering mid-shoot to fix a blurry page scrambles the sequence. Shoot retakes in a second pass at the end, then delete the bad pages while the paper is still on the desk.

Shredding before verifying. Page through the finished PDF on a bigger screen than the phone and read the first and last line of every page. Paper is the only backup until that check passes.

Quick answers about phone scanning

Do I need a scanner app, or is the camera enough?
Start with the scanner already on your phone: Notes on iPhone finds page edges itself, and Drive on Android scans to PDF directly. Plain photos work as a fallback with the same rules about light and angle.
Why do offices reject my phone photos of documents?
Almost always shadow or angle, not resolution. Even side light, the phone parallel to the paper, and the sheet filling the frame fix most rejections.
Can iPhone HEIC photos become a PDF directly?
Yes. The HEIC tool converts each photo's primary still image in the browser and keeps its decoded pixel dimensions, with no conversion step first.
When is a phone the wrong scanner?
For bound books that never lie flat, fragile sheets, and very large stacks. A library or copy shop flatbed beats an afternoon of phone photography for those.
