For combining multiple images into a single PDF there are three practical approaches depending on whether you want a quick GUI method, scripted/batch control, or professional PDF features. asked for the best way; pointed to web converters and suggested using a writer — below are alternative, local options plus tips to avoid common pitfalls.

Quick built-in methods

  • Windows: select the images in File Explorer, right-click -> Print -> choose Microsoft Print to PDF, set paper/orientation and save.
  • macOS: open the images in Preview, arrange thumbnails in the sidebar, then File -> Print -> Save as PDF.
    Always name files with zero-padded numbers (img_001.jpg, img_002.jpg) so the PDF pages appear in the intended order. If pages are rotated, EXIF orientation is usually the cause.

Command-line / batch (ImageMagick)

  • Useful for automation, bulk jobs, and resizing before combining. On ImageMagick v7 use magick; on older versions convert is used but can conflict on Windows. Example:
magick -auto-orient *.jpg -quality 85 output.pdf
  • -auto-orient fixes EXIF rotations, -quality controls JPEG compression inside the PDF. Add -resize WIDTHxHEIGHT\> to downscale large images. See ImageMagick docs: ImageMagick convert documentation.

Professional control and size optimization

  • Adobe Acrobat’s Combine Files gives fine control, OCR and optimization (commercial): .
  • To reduce an already-created PDF, Ghostscript can recompress it; use different -dPDFSETTINGS values (/screen, /ebook, /printer) to trade quality vs size.

Final tips

  • Test with a small subset to verify order, orientation, and filesize before processing everything.
  • If privacy matters, prefer local tools over online converters.
  • Keep originals until the final PDF is checked.

Another means is to create a Libre Office, or Open Office writer document and import the images, resizing them and positioning them to suit. Then, select the File->Export PDF option. Bingo!
