Soda PDF

Soda PDF works on various platforms. It is available in web and desktop formats.

This is how this software works to turn an image into a PDF:

Step 3: Import an image to the Soda PDF;

Step 4: After the image is loaded to the workstation, select Save or use Ctrl + S to export the newly created PDF file.

Note: The free conversion process only requires several steps, but unlike SwifDoo PDF, Soda PDF works to change an image to a PDF by the "Create" component. That well answers why it cannot adjust the page size and other appearance settings.

PDF Candy

What’s more important, PDF Candy Desktop is a robust PDF converting software as it supports many more file conversions among different formats, including MOBI, ODS, ODT, and ePub to PDF. Let’s go deeper into how we easily make PDFs from photos with PDF Candy. Let’s go deeper into how we make a picture a PDF in PDF Candy:

PDF Candy makes the image-to-PDF conversion much easier, but a non-paid user can only perform two free tasks. If users want more options, they must subscribe to a premium plan.

Preview

Mac users do not require external converters to convert an image to a PDF. The built-in Preview application has covered the fundamental conversion need. Since Preview is Mac’s default image viewer and PDF reader, we will exemplify how to make full use of this best converter on macOS:

Step 1: Open the image using Preview;

Step 2: Click Export To on the File tab;
