While this tool provides a highly accurate approximation of the resulting PDF, it's important to note that it is not an exact replica. Subtle differences may arise due to the variations in rendering across different platforms and the limitations inherent in simulating print-ready formats. Factors such as font rendering, spacing, and layout adjustments may contribute to slight discrepancies between the preview and the final PDF output. Users should consider this approximation as a close guide, rather than an identical representation, allowing for minor adjustments in the final product.
