Images to PDF Converter

How it works

1. Drop in your images, photos, scans, screenshots, in any mix of formats.
2. Put them in the order you want with the arrows.
3. Choose whether each page should match its image or be a standard paper size.
4. Press the button and the PDF is assembled on your machine.

About this tool

Combine any number of images into a single PDF. Reorder them before building, and choose whether each page should match the shape of its image or be a standard A4 or Letter page with the picture scaled and centred, the first is right for a photo album, the second for scans and receipts that need to print properly. JPEGs are embedded byte for byte, so nothing is re-compressed; other formats are converted losslessly on the way in. It all happens in your browser.

Which image formats does it take?

All of them: HEIC and HEIF straight off an iPhone, JPG, PNG, WebP, AVIF, GIF, BMP, SVG and ICO. Mix them freely in one document — a phone photo of a signed page, a screenshot of a confirmation email and a scanned receipt can all go into the same PDF, in whatever order you put them. There is no separate page per format here on purpose: the job is the same whatever you drop in, and a page for each combination would say the same thing eleven times.

If you want one PDF per image rather than one document, JPG to PDF, PNG to PDF and HEIC to PDF do that instead. And if the finished PDF is too large for wherever it is going, the reason is almost always the images inside it.

Match each image, or a paper size?

Match each image makes every page exactly the shape of the picture on it, with no borders and nothing cropped. That is right for a photo album or a set of screenshots. A4 or Letter gives you a document that prints properly and sits sensibly in a folder of other documents, each image is scaled to fit its page and centred, which is what you want for scans and receipts.

Are the images re-compressed?

JPEGs are embedded exactly as they are, byte for byte, so nothing is lost and nothing is added. Other formats are converted to a form PDF understands, which for PNG keeps every pixel. That means a PDF of JPEGs is roughly the size of those JPEGs added together, if the result is bigger than you want, compress the images first.

Does the order matter?

Pages appear in exactly the order shown in the list, which is why the arrows are there. Files usually arrive in the order your operating system lists them, which is not always the order you meant, worth a glance before you press the button.

The common trap is a folder of scans named page1.jpg through page12.jpg. Most systems sort those as text rather than as numbers, so page 10 lands immediately after page 1 and the document comes out in the wrong order with no warning. Renaming them with a leading zero — page01 — fixes it permanently, and reordering them here fixes it once.

What a photo of a document costs

A phone photograph of a signed page makes a perfectly valid PDF and a surprisingly bad document. Three megapixels of camera noise are stored where a scan would have stored flat white, so the file is five to ten times larger than it needs to be; the page is rarely square to the camera, so it prints with one edge shorter than the other; and the text is a photograph of text, meaning nobody can search it, select it or copy a line out of it. None of that matters for a receipt going into an expenses claim. All of it matters for something being filed, signed or read by a person who will want to quote it back. Where the choice exists, a flatbed scan or a phone scanner app that flattens and thresholds the page produces a smaller, straighter and far more legible PDF than the camera does.

Will the finished PDF have my location in it?

If it was built from phone photographs, quite possibly. A JPEG is embedded byte for byte, which is what keeps the quality intact, and that includes whatever Exif block the photo was carrying — the camera model, the timestamp and often the GPS coordinates where it was taken. The PDF itself gets no metadata of its own from this tool, but it does inherit whatever was already inside the pictures. If the document is going to anyone outside your own machine, run the images through Clean first, or the finished PDF through it afterwards. This is the one part of the job the format does not handle for you, and what a photograph is actually carrying explains why it is worth the extra step.
