Introduction
Whether you're submitting a scanned form, sharing a photo portfolio, or creating a multi-page document from screenshots, converting images to PDF is one of the most common document tasks. There are at least ten solid ways to do it — each suited to different situations, operating systems, and skill levels.
The 10 Methods
PDFMagik – Free Online Tool (Fastest for Most People)
Go to PDFMagik's Image to PDF converter, upload one or more images (JPG, PNG, WEBP, TIFF, BMP), reorder them if needed, and click Convert. Done in under 30 seconds. No account required, no watermarks.
Best for: Quick conversions, multiple images, any OS.
Windows Print to PDF (Built-in, Zero Cost)

macOS Preview (Best for Mac Users)
Open your images in Preview. Select all thumbnails in the sidebar, then go to File → Export as PDF. Preview preserves full resolution and handles multi-page PDFs elegantly.
Best for: Mac users wanting high-quality output.
Google Docs (Free, Anywhere)
Insert your image into a new Google Doc, then go to File → Download → PDF Document. Works from any browser, any OS.

Adobe Acrobat (Premium, Most Control)
In Acrobat Pro, go to File → Create → PDF from File and select your images. Acrobat lets you set page size, margins, and image compression.

LibreOffice (Free Desktop App)
Insert images into a LibreOffice Writer document and export via File → Export as PDF. Gives you fine-grained control over compression, image DPI, and security settings — all free.
ImageMagick Command Line (Power Users)
A single command converts a folder of images to a PDF:
convert *.jpg -auto-orient output.pdfAdd -density 150 to control DPI. Free, cross-platform, handles batch processing beautifully.
Python with img2pdf
import img2pdf
open("out.pdf","wb").write(img2pdf.convert(["a.jpg","b.jpg"]))Unlike ImageMagick, img2pdf embeds JPEG images without re-encoding — meaning zero quality loss.
Microsoft Office Word or PowerPoint
Insert your image into a Word document or PowerPoint slide, then use File → Save As → PDF. Both apps produce clean PDFs and are installed on most Windows PCs.
Mobile – iOS Files App / Android Google Drive
On iPhone: open an image in Photos, tap Share → Print → pinch-zoom the preview to detach the PDF. On Android: upload to Google Drive, then use Drive's built-in PDF creation.
Which Method Should You Use?
For most people, most of the time: an online tool like PDFMagik is the fastest and simplest answer. If you're on a Mac, Preview is excellent. For bulk automation, Python's img2pdf or ImageMagick are unbeatable.
💡 Quality Tip: To preserve maximum image quality, avoid tools that re-encode JPEGs. The img2pdf library and PDFMagik both embed JPEG data directly, bypassing re-compression entirely.
