Why turn photos into a PDF?
Offices, universities, embassies and landlords usually ask for documents as a PDF rather than loose photos. If you photographed a payslip, a passport page or a signed form with your phone, this tool puts the pictures into a single tidy PDF that prints at the right size and opens on any device.
Choosing the settings
- Page size: A4 is the standard in the UK, Europe, the Middle East and Asia; US Letter is used in the US and Canada. Same as each image makes every page exactly the size of its picture – good for screenshots or artwork that should not have white borders.
- Orientation: Automatic turns a page sideways when the photo is wider than it is tall, so landscape pictures fill the page.
- Margin: a small margin looks like a normal printed document and stops printers cutting off the edge.
Each image is scaled to fit inside the margins without stretching and is centred on its page. JPEG and PNG files are placed exactly as they are; WebP and GIF images are converted to high-quality JPEG first, because the PDF format has no WebP support.
Worked example: a phone photo of a payslip that is 3024 × 4032 pixels (portrait, 3:4) on A4 with a 10 mm margin has an area of 190 × 277 mm to fill. Keeping its shape, the width is the limit, so the photo becomes 190 mm wide by 253 mm high and is centred with about 12 mm of extra white space above and below.
Tips for clear scanned documents
- Photograph the paper flat on a dark table in daylight, with the phone held straight above it.
- Crop away the table before converting – most phone photo apps have a crop button.
- If the PDF is too big to email, shrink the photos with the image resizer first (1600 px wide is plenty for A4).
