How to convert JPG to PDF

This JPG to PDF converter turns one or more images into a single PDF document, with one image per page. It also accepts PNG and WebP.

1. Choose your images or drop them on the box. You can select many at once, add more later, or paste a screenshot with Ctrl+V.
2. Arrange the pages. The number on each thumbnail is its page number; the arrow buttons move it earlier or later, and × removes it.
3. Pick a page size, orientation and margin. The preview on the right shows exactly how each page will look.
4. Press Create PDF, then Download PDF.

The page opens with a sample photo so you can try the settings straight away. It disappears as soon as you add your own images.

Page size, orientation and margin

With A4 or Letter, each image is scaled to fit inside the page and centred, so nothing is cropped or stretched. Auto orientation turns a page to landscape when its image is wider than it is tall, which makes wide photos and scanned receipts use the space better. Choose Portrait or Landscape to make every page the same.

The margin is the white border around the image: none, small (about 7 mm) or large (about 18 mm). Printers usually cannot print to the very edge of the paper, so a small margin is a safe choice when the PDF will be printed. With Fit to image, the page is sized at 96 pixels per inch, the standard screen resolution, plus the margin you choose.

How the conversion works

Everything happens in your browser using the open source pdf-lib library, which loads only when you press Create PDF. Your images are not uploaded.

• JPG files are copied into the PDF byte for byte. There is no recompression, so the quality is identical to your original and the PDF is only slightly larger than the photos themselves.
• PNG files are embedded losslessly. Transparent areas show the white page behind them.
• WebP is not supported inside PDF files, so it is first redrawn on a canvas and saved as high quality JPG, or as PNG when the image has transparency.
• Phone photos often store their rotation as a separate tag. The tool reads that tag and corrects the image, so a portrait photo does not end up sideways in the PDF.

Tips

• For documents photographed with a phone, crop away the table or background first. The page will look much cleaner.
• If an upload form has a size limit, run large photos through an image compressor before converting. A 4 MB phone photo becomes a 4 MB page.
• Need to add an existing PDF to your images? Create the PDF here, then combine both files with the Merge PDF tool.
• Screenshots and diagrams look sharper as PNG; photos are smaller as JPG.

Limits

HEIC photos from iPhones cannot be read by most browsers, so convert them to JPG first or set the camera to "Most Compatible". Very large batches of high resolution photos use a lot of memory; on a phone, around 50 photos at a time works comfortably. The PDF contains images only, so the text in a photographed document is not searchable unless you run it through OCR software afterwards.
