How to Convert JPG Photos to a Single PDF on Any Device

Phones turned everyone into a document scanner. Receipts, IDs, signed forms, whiteboards after a meeting — they all end up as JPG photos in your camera roll. The problem comes when you need to submit them: portals and HR departments want "one PDF", not eleven photos attached in random order.

The fast way, on any device

Because our JPG to PDF tool runs in the browser, the steps are the same on Windows, Mac, Linux, iPhone and Android:

1. Open the tool and add your photos (JPG, PNG and WebP all work).
2. Drag them into the right order.
3. Pick a page size — A4 or US Letter for documents, Fit to image for screenshots and artwork.
4. Click Create PDF. Done.

Your photos never upload anywhere — the PDF is assembled on your device. For pictures of your passport, that's not a nice-to-have.

Getting the layout right

A few options make the difference between "photos stapled into a file" and a document that looks deliberate:

Page size. If the PDF is paperwork — receipts for expenses, a signed form — choose A4 or Letter so it prints naturally. Choose Fit to image when the image is the content: screenshots, design mockups, artwork. Each page then matches its image exactly, no borders.

Orientation. Auto rotates each page to match its photo (landscape photos get landscape pages). Forcing portrait keeps a stack of receipts uniform even when one was shot sideways.

Margins. A small margin (the default) looks tidy for documents. Zero margins edge-to-edge for photos.

Images per page. Two or four per page turns a pile of small receipts into a compact expense report — four receipts per A4 sheet reads perfectly and quarters the page count.

Three habits that make photographed documents look professional

1. Shoot straight-on, fill the frame. Hold the phone parallel to the paper and get close. Skewed keystone-shaped pages scream "photo of a document"; straight-on shots read like scans.
2. Mind the lighting. Daylight beats lamps; avoid your own shadow across the page. A dim photo of a receipt is the one the finance team bounces back.
3. Order before you convert. Drag the images into reading order in the tool — it's much easier than fixing page order afterwards.

Common follow-ups

The PDF came out huge. Phone photos are 3–12 MB each, and the PDF embeds them at original quality. Run the result through Compress PDF — photographed documents compress dramatically with no visible loss.

I need to add the photos to an existing PDF. Skip the separate conversion: the Merge PDF tool accepts images directly alongside PDFs and converts them to pages on the fly.

The orientation is wrong on one page. Convert anyway, then fix that single page with Rotate PDF — it can rotate just the pages you select.
