A flatter receipt, with the print lifted enough to read
Straighten a slip that curled
Receipts rarely lie flat. You photograph the page, and the scanner straightens the four corners onto a sheet. That is what turns a tilted phone shot into a page you can file. Help it by filling the frame and using a plain background, so the corners of the paper are obvious. If a curl hides a line, smooth the slip and shoot again. The preview should show the whole receipt, from the shop name to the last amount, inside the page. Standard document mode is the path for this, one receipt in the frame. When the corners sit on the paper, the rest of the scan has a fair chance.
Magic Color, Original, or Black and White
Magic Color is the default, and it earns that place on a thermal receipt. Those slips fade, and the boost in contrast makes the items and the total easier to see in the picture you keep. Switch to Original if the receipt is already crisp and you prefer the untouched look, including any colored stamp. Choose Black and White when you want the type to read like ink and the paper tone to drop away. Compare them on the preview, especially around the total and the date. The right filter is the one that makes those lines comfortable. You can decide after the corners are set, and the download uses the look you picked.
PNG, or a one-page PDF on A4
Save a PNG when you want the receipt as an image. Save the one-page PDF when you want a document to attach. That PDF fits the scan on A4 and embeds a JPEG at quality 0.92, so the page is a normal PDF with the receipt on it. Open the download and read the merchant, the date, and the total before you file it. On a phone, the capture control uses capture=environment and opens the camera app. Take the shot there, then return and straighten. The scan stays in the browser. Keep the file with the rest of that day's papers, under a name that includes the store or the date, so you can find the picture later.
How it works
- 1
Photograph one receipt
Use standard document mode. On a phone, capture=environment opens the camera app. Fill the frame with the slip, on a plain surface, and include the shop name, the date, and the total.

Straighten the corners and pick a filter
Confirm the corners sit on the paper. Magic Color is the default. Switch to Original or Black and White if the print reads better that way. The boost in contrast is there for a faded slip.

Download PNG or a one-page PDF
PNG saves the picture. The PDF is one page, with a JPEG at quality 0.92 fitted on A4. Open it, read the total, and file it. The scan stays in the browser.
Use cases
A faded thermal slip
Magic Color lifts a pale receipt so the lines are easier to see in the photo you keep. Straighten it first so the rows stay level.
A receipt to attach
Download the one-page PDF, JPEG at quality 0.92 on A4, and attach that file. The merchant and the total should be readable on the page.
A wrinkled paper to flatten
Smooth the slip, shoot it, and let the corner warp square the page. A PNG is a handy image of that flatter receipt for your own files.
Problems we solve
A shiny patch hides the total
Move the lamp and tilt the receipt slightly until the amount returns. Shoot again. Magic Color can lift faint ink, and it needs the ink to be in the photo.
The corners grabbed the table
Drag the corners onto the paper. A busy background confuses the edge of a thin slip. A dark, plain surface under the receipt makes the next try cleaner.
