Turn photos into a single PDF — the right way to send scanned documents

Someone asks for "your ID and a utility bill," and you photograph both with your phone. Now you've got two JPGs. Do you really attach two loose photos to the email? A pile of phone photos says "I did this in a hurry"; a single, tidy PDF says "here's my document." For anything official — applications, claims, reimbursements, sign-ups — turning your photos into one PDF is the difference between looking organised and looking like you guessed.

Why a PDF beats loose images

It's not just appearances, though that matters. A PDF solves real problems that a folder of JPGs creates:

• One file, in order. The recipient opens one attachment and pages through it, instead of juggling five images and trying to figure out the sequence.
• It prints predictably. Photos print at whatever random size the viewer decides; a PDF page is a defined size (A4, Letter) that comes out right.
• It's the expected format. Forms and portals ask for "a PDF." Handing them what they asked for avoids the "please combine these into a single document" reply.
• It travels as a unit. Nothing gets lost or reordered between you and them.

Page size and orientation actually matter

This is the part people skip, and it's why some image-to-PDF results look off. Your photo and the PDF page are two different shapes, and how the tool reconciles them changes the result:

• Orientation: a landscape photo dropped onto a portrait page leaves big empty margins top and bottom. Match the page orientation to the photo (or let each page follow its image) and it fills the space.
• Fit: "fit" keeps the whole photo visible with some margin; "fill" crops to the page edges. For documents you almost always want fit, so nothing gets cut off.
• Page size: A4 or Letter for anything that'll be printed; match your region's standard.

Get these right and your scan looks deliberate. Get them wrong and you get a document that's mostly white space with a small photo floating in it.

For document scans specifically: portrait page, "fit" so nothing's cropped, and a consistent page size across all the photos. That combination reads as a real scanned document rather than snapshots pasted into a file.

Keep your documents off other people's servers

The photos you're combining are usually exactly the sensitive kind — an ID, a bill with your address, a signed form. So the same rule as every other PDF task applies: there's no need to upload them. A browser can assemble the PDF locally.

Primova's Image to PDF converter takes one or more images, lets you set page size and orientation and arrange the order, and builds a single PDF — entirely in your browser. Nothing is uploaded, there's no account, and no watermark lands on the result.

Drag your photos in, drop them into order, pick portrait or landscape, and download one clean document: Image to PDF. It pairs well with the merger too, when you need to staple your new scan onto an existing PDF.
