We are living in a digital world, where most people rely on static images to share information via email. While this may seem convenient, sending image files individually in an email often falls short in terms of professionalism and user experience.
Apart from this, it also increases the chances that you may reach the email attachment size limit. Due to these limitations, PDFs are becoming the go-to format for businesses, freelancers, marketers, etc., when it comes to sharing attachments via email.
PDFs deliver a seamless viewing experience by retaining image quality and maintaining the formatting across different devices. In short, such files offer an elite-level presentation that improves readability and professionalism.
What’s surprising is that adopting this elite-looking approach doesn’t cost a single penny. By following a few simple steps, you can transform images into a PDF file.
Why Sending PDF-based Documents Instead of Images in Email Looks Good
There are several reasons why someone should send an attachment as a PDF file rather than individual images.
1. Perfectly Preserved Quality
When it comes to the viewing experience, quality is an important characteristic. However, when you send images in email, their quality in terms of resolution gets compromised. This is because whenever the recipient zooms in on a photo to understand, its pixels will explode, causing blurriness.
Fortunately, this won’t be the case if you share images in the PDF document. This format is specifically designed to preserve both the quality and formatting of the image. This means no matter how much you zoom in on the photo, its quality will remain the same as the original variant.
2. Reduced File Size
The standard email attachment size is 25Mb…right? So, if you send multiple images in an email, there is a strong probability that the attachment limit will be exceeded, ultimately resulting in an error. Because an average high-resolution photo taken from a phone’s camera has a size greater than 2MB.
Here, again PDF document stands out as a more suitable option. Transforming images into a PDF file will effectively compress their overall size without sacrificing their quality in terms of resolution.
This capability makes PDF an ideal yet professional-looking option for sending visually rich documents in a lightweight format via email.

3. Enhanced Security
We all know that sending images in an email offers no security. Anyone can download, alter, and use them as per their specific needs and requirements. On the other hand, PDF documents offer robust features.
For instance, you can encrypt the PDF file with a password, so that only authorized individuals can access it. Apart from this, you can even restrict the editing, copying, and printing permissions.
This makes them a safer option for sending confidential information via email.
4. Seamless Printing & Archiving
This is yet another reason why sending PDF documents in email instead of plain images looks elite. Email communication is generally preferred for professional purposes. This means the recipient may come across the need to print your attachment.
So, if you have sent multiple images, it will ultimately become cumbersome to print, and also may not scale properly. Whereas, PDF documents are specifically built for both print and seamless archiving. These perfectly maintain margins, support page breaks, etc., for better readability.
How to Transform Images into a PDF Document for Free
Here is the step-by-step procedure that should be followed for quickly and efficiently converting image files into scannable and shareable PDF documents.
1. Opt for a JPG to PDF Converter
There is a huge variety of converters available that can help you transform images into PDFs. All of them are free to use and feature a user-intuitive interface for easy navigation.
So, you can go with any based on your personal needs and preferences.
However, we personally suggest choosing one that:
- Allows the conversion of several images into a single PDF document
- Does not ask for signup/registration to perform the conversion process
- Does not implement a watermark on the PDF document
2. Upload Images & Start Conversion
When the tool is selected, all you need to do is simply upload all the images to it. For demonstration, we picked a JPG to PDF converter by considering the aforementioned requirements and its ranking in search results.
After uploading multiple images to it, this is how its interface now looks:

Now, hit the “Convert to PDF” button to start the conversion process.
3. Download the Converted File
