Turn a photo of a document into a scanned PDF

Make a phone photo of a document look scanned: the page is straightened, the shadows go and the paper turns white with dark text, in a PDF. Free, no upload.

Before you start

Have photos of a document in your gallery or in a chat, and a form that asks for a scanned copy? This page opens the document scanner. Press "Choose photos" and pick them. Each page is found and straightened, the shadows are evened out, and the paper turns white with dark text, like a page from a scanner. Then you get one PDF.

It is still your photo, cleaned up. Nothing on the page is changed or typed again, and the scan is about as sharp as the photo was. With no size limit, pages are saved at up to 250 DPI, but never sharper than the photo they come from.

Tips

A worked example: the two sample pages

The scanner's sample is two phone-style photos, 1500 × 2000 pixels each, of a printed statement and an invoice lying tilted on a wooden table, with a shadow, a dark corner and some camera grain. The scanner cut away the table, straightened both pages and made the paper white.

The PDF of the two pages was about 310 KB in Color and 266 KB in Black & white, as the result page shows them. Both were saved at 134 DPI, not 250: each page fills only part of its photo, so it holds about 134 DPI of detail, and a scan is never made sharper than its photo.

Questions and answers

How do I make a photo look like a scanned document?

Add the photo on this page. The scanner finds the page, straightens it, evens out the light and makes the paper white, then saves a PDF. Check the corners of each page before you press Download PDF.

Can it fix a blurry or cut-off photo?

No. It cannot sharpen a blurry photo, bring back a corner that is outside the photo, or remove a finger that covers the text. Take the photo again if you can: hold the phone steady, straight above the page, with all four corners in view.

Is a cleaned-up photo the same as a real scan?

It looks much like one, but it comes from a photo, so it is only as sharp as the photo. If a form says the copy must come from a scanner, ask the office whether a phone scan is accepted.

Can I put a photo into a PDF without changing it?

Yes, with JPG to PDF. It puts your photos into a PDF as they are, on A4 or US Letter pages, without finding the page or cleaning it up.
