A PDF is the easiest way to share a set of images as one tidy file — scanned documents, a photo portfolio, receipts, a set of screenshots, or anything you’d rather not send as a dozen separate attachments. This guide shows how to combine images into a single PDF, get the page order and size right, and do it privately without uploading anything.
TL;DR — Add your images to the free image-to-PDF tool, drag them into order, choose a page size, and download one combined PDF. It’s built in your browser — nothing is uploaded.
When you’d convert images to PDF
- Scanned documents — turn phone photos of pages into one shareable, printable file.
- Portfolios and proofs — send a client a single PDF instead of a folder of JPGs.
- Receipts and records — combine expense photos into one document for filing.
- Screenshots — bundle a sequence of screens into a step-by-step PDF.
In every case the win is the same: one file, in order, that opens anywhere.
Getting the page order right
In a PDF, sequence matters — page 1, page 2, page 3. So before you export:
- Add all the images first.
- Reorder them into the exact sequence you want (the tool numbers each one and lets you move them up or down).
- Remove any you added by mistake.
Each image becomes one page, in the order you set. Getting this right before exporting saves re-doing it later.
Choosing a page size
This is the one setting worth a moment’s thought:
| Option | What it does | Best for |
|---|---|---|
| Fit to image | Each page matches its image exactly — no borders | Portfolios, screenshots, photo sets |
| A4 / Letter | Each image is centred on a standard page | Documents, anything you’ll print |
For A4 or Letter you can also choose portrait or landscape and a margin, so scanned pages sit neatly with a clean border. For fit-to-image, the page simply takes the shape of each photo — ideal when you don’t want any white space.
Tip: Mixing portrait and landscape photos? “Auto” orientation rotates each page to match its image, so nothing ends up sideways.
Step by step: combine images into a PDF
- Open the image-to-PDF tool.
- Drop in your images — JPG, PNG, WebP and more are all supported.
- Drag them into order and remove any extras.
- Pick a page size — fit-to-image, or A4/Letter with orientation and margin.
- Download your single, combined PDF.
The whole thing runs on your device, so your documents and photos stay private — nothing is uploaded, and there’s no sign-up or watermark.
Keep the PDF small
Lots of high-resolution photos make a heavy PDF. To keep the file manageable:
- Resize oversized photos to a sensible width before converting.
- Compress the images first so each page is lean.
A document scan doesn’t need 12-megapixel pages — resizing to around 1500px wide keeps text readable while dramatically shrinking the final PDF.
Where to go next
- Compress images without losing quality — shrink each page before you combine.
- Resize images for the web — right-size oversized photos first.
- Convert images to WebP and AVIF — for sharing images on the web instead.
