Images in JPG are widely used for photos, scans, and screenshots. However, when you need to share, submit, or print multiple images with consistent formatting, converting these images into PDF becomes essential. PDFs preserve layout, prevent image compression, and are easier to combine into one file.
Whether you're on Windows, Mac, iOS, Android, or just browsing online, this guide will show you exactly how to convert JPG to PDF—and other image types too—quickly and for free. Let's dive in!
How to Convert JPG to PDF on Mac with Built-In Preview App

Step 1: Open your JPG (or JPEG, PNG, etc.) in Preview.
Step 2: Go to the File menu and choose Export as PDF.
Step 3: Choose the destination and click Save.
💡Tip: You can open and combine multiple images in Preview, arrange them in the sidebar, then go to File > Print > Save as PDF to create a single PDF file from multiple JPGs.
