When converting an image to PDF, making edits, and then converting it back to an image, you may notice that the final output dimensions don’t match the original.
For example, an image with dimensions 1080 × 1350 might appear resized after the PDF-to-PNG conversion.
Solution
To ensure the output image retains the same size as the original, set the resolution to 96 DPI in the PDF to PNG module.
How to Set the Resolution
You can specify the resolution using the following profile:
{ "RenderingResolution": 96 }
Result
By applying this setting, the converted image will maintain the same dimensions as the input file.
