How to convert images to a PDF

Turn photos and screenshots into a single document, one image per page.

Photographing documents with a phone is the fastest scanner most people own. The output, though, is a folder of images — and every expense system, application form and filing process wants one PDF.

Combining them is straightforward. The settings worth understanding are page size and rotation.

The steps

  1. Upload one or more images.
  2. Choose a page size: match each image automatically, or force A4, Letter or Legal.
  3. Set a margin, and decide whether pages may rotate to fit landscape images.
  4. Run the tool and download the compiled PDF.

Automatic or fixed page size

Automatic creates each page at the size of the image it holds, so nothing is scaled, cropped or letterboxed. It is the right choice when the images are the content and nobody is going to print the result.

A fixed size — A4, Letter or Legal — gives a document that prints predictably and looks consistent, at the cost of white space around images whose proportions differ from the page.

Rotation and margins

Automatic rotation turns the page to match a landscape image rather than shrinking it to fit a portrait page. With a fixed page size and a mix of orientations, this is usually what you want.

A margin adds breathing room around each image, which matters if the document will be printed and bound — content too close to the edge disappears into the binding.

Order, and what comes after

Images are combined in the order shown on screen, which you can change before running. Phone photographs are large, so the resulting PDF often is too: compress it afterwards if it needs to be emailed.

Common questions

What does 'auto' page size do?
Each page is created at the size of the image it holds, so nothing is scaled or letterboxed.
Will my images be re-compressed?
Images are placed into the PDF as they are. If the result is larger than you would like, run Compress PDF afterwards.
In what order do the images appear?
In the order shown on screen, which you can rearrange before running the tool.
