img2pdf, a free command-line tool for converting images to PDF on Windows, macOS, and Linux. It is useful if you want a lightweight option without opening a full PDF editor. It works well for JPG, PNG, TIFF, and other common image files.

# Single image
img2pdf image.jpg -o output.pdf

# Multiple images into one PDF
img2pdf image1.jpg image2.png -o output.pdf

# All JPGs in a folder
img2pdf *.jpg -o output.pdf

# Set page size
img2pdf image.jpg --pagesize A4 -o output.pdf

One big advantage of img2pdf is that it can create PDF files without re-encoding JPEG images, so the output can keep the original image quality and avoid unnecessary file size increase. It is also good for batch conversion, especially if you have many images in one folder.

The downside is that img2pdf is not very beginner-friendly because it mainly runs from Command Prompt or PowerShell. If you are comfortable with commands, it is fast and reliable. If you prefer a visual interface, Adobe Acrobat or Microsoft Print to PDF may be easier.
