PaperCrane
Android app by Prami, India

A free document scanner with no ads in it.

Hold your phone over a page. PaperCrane waits until your hand is steady, takes the photo, straightens the page and saves it as a PDF. It also turns Word, Excel and text files, and web pages, into PDFs.

Needs Android 8 or newer. No account, no sign-up.

01 · Scanning

It takes the photo when your hand stops moving.

Leave it on Auto and hold the phone over the page. Once the outline settles, PaperCrane takes the picture itself. Everything outside the outline is blurred, so you can see exactly what will be saved.

Keep scanning page after page, then tap Save once. All the pages go into one PDF.

02 · Fixing a page

Rotate, filter or crop with one tap.

After a scan there are four buttons under the page. Rotate turns it a quarter turn. Filter switches between Enhanced, Original, Grayscale and Black & white. Crop lets you drag the four corners. Delete removes the page.

You can reorder or delete pages later from the document.

03 · File names

Files are named after what's on the page.

PaperCrane reads the text on the page and names the file Receipt, Invoice or Contract instead of a string of numbers. If it can't tell, the file is called Scan. You can rename anything.

Each document can be saved or shared as a PDF, or as JPEG, PNG or WebP images.

04 · Converting

It converts files, not just paper.

Pick one file or several, choose PDF or an image format, and preview the result before you save or share it.
