Building a Simple Image to PDF Workflow (and a Free Tool You Can Use)

PDF is one of the most widely used formats for sharing documents across platforms. Developers, designers, and students often need to convert images (JPG, PNG, etc.) into PDF files — whether for document submission, archiving, or combining multiple scans into a single file.

In this article, I’ll explain why image-to-PDF conversion is so useful, outline a simple workflow, and share a free online tool you can use right away: Image2PDF.vu.

Why Convert Images to PDF?
• Cross-platform compatibility → PDFs open on virtually any device.
• Compression → a single PDF can be lighter than multiple images.
• Professional look → great for resumes, project reports, and official documents.
• Batch support → merge multiple images into one file without hassle.

A Simple Image-to-PDF Workflow (as a Developer)

If you want to build your own pipeline or just understand how it works, here’s the basic logic:


from fpdf import FPDF
from PIL import Image

def images_to_pdf(image_list, output_pdf):
pdf = FPDF()
for image_path in image_list:
cover = Image.open(image_path)
width, height = cover.size
pdf.add_page()
pdf.image(image_path, 0, 0, width / 4, height / 4) # scaling
pdf.output(output_pdf, "F")

images = ["doc1.jpg", "doc2.png", "doc3.jpeg"]
images_to_pdf(images, "output.pdf")


For Non-Coders (or Quick Conversions)

Of course, not everyone wants to write code for this. Sometimes you just need a fast and reliable web tool.

That’s where Image2PDF.vu comes in:
• Free, no installation required.
• Works directly in the browser.
• Supports multiple image formats.
• Lets you upload, reorder, and convert images in seconds.

➡️ Try it here: Image2PDF.vu.

Whether you’re coding your own script or using a ready-made online service, converting images to PDF is an essential workflow in today’s digital world.
• Developers can automate the process with Python (great for batch jobs).
• Everyday users can just use tools like Image2PDF.vu for quick conversions.

Both approaches save time, reduce file clutter, and make document sharing much easier.
