A free PDF scanner app uses your phone's camera to photograph documents, straighten and clean them up, and save them as PDFs you can email or store. Many add text recognition, which makes the words in a scan searchable. Check the apps you already have first, because some cloud storage apps include a scanner.
Paper has a way of piling up: receipts, letters, signed forms and school notes. A scanner app turns each one into a tidy PDF in seconds, and you don't need a scanner on your desk.
Here are ten free PDF scanner apps, in no particular order and sorted alphabetically. Some are simple scanners, some add text recognition and editing, and one is built into a cloud storage app you might already have.
Every app here is a free download on Google Play, though many offer upgrades inside the app, and a few show ads. The store labels in the table tell you which.
The best free scanner may already be on your phone, and it's easy to miss, as the next section explains.

The scanner hiding in your cloud storage app
Here's the detail many people miss. Google Drive Help explains that you can scan documents like receipts, letters and billing statements with the Drive app on Android and save them as searchable PDFs in your Drive. You open the app, tap the camera button and point your phone at the page.
The same help page says Google doesn't use your Drive content for advertising. So if you're already using it for files, try its scanner before you install anything else. A separate scanner app makes sense when you want extra editing tools, book scanning or a different cloud service.
What makes a scan look professional
- Light: scan near a window or under a bright lamp.
- Contrast: put pale paper on a dark surface.
- Edges: let the app find the corners, then check them.
- Text recognition: turn it on so you can search the PDF later.
- File size: choose a smaller size for email attachments.
Scanning a document in under a minute
- Flatten the page and place it on a dark, even surface.
- Open your scanner and hold the phone straight above the page.
- Let the app capture the page, then adjust the corners.
- Add more pages to the same file if it's a multi-page document.
- Save it as a PDF with a clear name and the date.
Keeping scanned paperwork organised
Scanning only helps if you're able to find the file again. Pick one folder for each part of life, such as home, work and health, and name each file with the date first so they sort in order.
Then shred or recycle the paper you don't need to keep. Check first which originals you're required to hold on to, such as some tax or identity documents, because a scan isn't always enough.

My plain advice on scanner apps
Start with the scanner you already have. If your cloud storage app includes one, it'll probably cover receipts and letters with no extra app at all.
If you scan every day, pick one dedicated app with clean store labels and text recognition, and use it for everything. One habit beats three half-used apps.
