How to Convert an Image to PDF on Any Device

Step-by-step ways to turn a JPG or PNG into a PDF on Windows, Mac, iPhone, Android or in your browser.

Updated 21 October 2026

You need a PDF when a website, school or office will not accept a photo, or when you want several pictures in one tidy file. PDFs open the same way on every device, keep their page layout, and are the format most upload portals ask for. Here are the quickest ways to convert an image to PDF on each device, and what to do when something goes wrong.

The fastest way: an online image to PDF converter

Open the free image to PDF converter and choose your image, or drag it onto the box.
Pick a page size. “Same as image” leaves the picture untouched, while A4 or US Letter suits documents you plan to print.
Click Convert to PDF and the file downloads to your device.

This converter works inside your browser, so nothing is uploaded. That makes it a sensible choice for IDs, contracts and other private documents. It works the same on a phone, tablet or computer, and there is no app to install.

On Windows

Open the image in the Photos app, choose Print, pick Microsoft Print to PDF as the printer and save. Menu names vary a little between Windows versions. This method makes one PDF per image, so for several pictures it is quicker to use the online converter.

On a Mac

Open the image in Preview, then choose File and Export as PDF. Print followed by Save as PDF also works. To combine several images, select them all in Finder and open them together in Preview before exporting.

On an iPhone or iPad

Open the photo, tap Share, then Print. Pinch outward on the small preview to open it full size, tap Share again and save the PDF to Files. The pinch gesture is easy to miss. Alternatively, open the converter in Safari, add your photos from the library and convert them in one go.

On Android

In many apps, such as Chrome or Files, you can choose Print and then Save as PDF. The exact menu depends on your phone and app. The browser method works on any Android phone with Chrome or a similar browser.

Which image format should you start with?

JPG: best for photos and phone pictures. See our JPG to PDF guide.
PNG: best for screenshots and graphics. See our PNG to PDF guide.
WebP, AVIF, BMP, GIF: work in most modern browsers. A GIF becomes a PDF page from its first frame.
HEIC (iPhone photos): opens only in browsers that support it, such as Safari. On an iPhone you can switch Settings, Camera, Formats to Most Compatible so new photos are saved as JPG.

Common problems and fixes

The photo is sideways: press the rotate button on the thumbnail before converting.
The PDF is too big to email: choose Balanced or Small file quality. Our guide on making a PDF from images smaller explains how.
Text is hard to read: retake the photo in good light, straight on, and use High quality.
You have many pictures: add them all at once and arrange them. See how to combine images into one PDF.

Tips for a better PDF

Crop and straighten the photo first so the page is not full of empty table or floor.
Photograph documents in good light with the camera directly above the page.
Use A4 or Letter for anything that will be printed, and “Same as image” for anything read on screen.
