How to Convert an Image to PDF
- Add your images. Drop JPG, PNG, HEIC (iPhone), WebP or other images into the box above, or paste a screenshot.
- Set the order. Each image becomes one page. Use the ▲ ▼ arrows to arrange them.
- Choose a page size. Fit to image keeps each page exactly the size of the picture. US Letter, A4 or Legal places each image on a standard sheet, which is ideal for printing and forms.
- Pick orientation and margin (Auto rotates landscape photos onto landscape pages).
- Click Convert. The PDF opens in a preview, then download it. Turn off Combine into one PDF to get one PDF per image.
Which Page Size Should I Choose?
| Page size | Best for |
|---|---|
| Fit to image | Sharing on screen, portfolios, screenshots. No white borders |
| US Letter (8.5 × 11 in) | Printing in the US and Canada, job applications, school assignments |
| A4 (210 × 297 mm) | Printing outside North America, international forms |
| US Legal (8.5 × 14 in) | Legal and real-estate documents |
How to Convert an Image to PDF on iPhone
Save the photos to the Files app, tap Select, choose the images, then tap More (•••) and Create PDF. It's quick, but you can't choose a page size or margins. In Safari, the converter above also reads HEIC photos directly and lets you set US Letter or A4 pages.
How to Save an Image as a PDF on Windows and Mac
- Windows: open the image in Photos, press Ctrl + P and choose Microsoft Print to PDF as the printer.
- Mac: open the image in Preview and choose File → Export as PDF.
Both are fine for a single image. For many images in one document, or a consistent page size, use the tool above.
Tip: Scanning a multi-page document with your phone? Take one photo per page, add them all here, and choose US Letter with a small margin for a clean, print-ready PDF.
Private and Free

Works on Every Device
The Image to PDF Converter runs in any modern browser: Chrome, Safari, Edge and Firefox on Windows, Mac, Chromebook, iPhone, iPad and Android. Because everything happens on your device, it's fast even on slow connections and keeps working if your internet drops after the page loads. There are no file-size caps set by a server, and no account, email address or watermark is required.
Troubleshooting & Tips
- Photos come out sideways Some phone photos store their rotation separately. Modern browsers apply it automatically; if not, rotate the photo in your gallery and save it again.
- There's a white border around my image That's the margin on Letter or A4 pages. Choose Fit to image, or set Margin to None.
- The PDF is too large Lower the quality slider to around 75% before converting.
- HEIC photo shows an error A few HEIC variants can't be decoded in the browser. Export the photo as JPG from Photos and try again.
