Image to PDF Converter

In professional document management, the integrity of visual assets during format migration is non-negotiable. This tool is engineered for high-volume, high-fidelity archival tasks where precise control over physical output dimensions is required. Unlike consumer-grade tools that simply embed images, this system calculates the exact render-box dimensions based on international paper standards (ISO 216, ANSI, JIS) and pixel density constraints.

The architecture operates strictly on the Client-Side (Local Browser Environment). This is a critical security feature for legal, medical, and financial sectors; your sensitive contracts, receipts, or blueprints are processed in your device's Random Access Memory (RAM) and never transmitted over a network. This zero-trust architecture eliminates the risk of Man-in-the-Middle (MitM) attacks during file upload.

We employ advanced CSS Paged Media logic to inject print directives directly into the rendering engine. This ensures that when the browser generates the PDF, it respects hardware margins, bleed areas, and image interpolation algorithms, resulting in a vector-container format that retains the maximum possible raster quality of the source files.

To prevent pixelation (aliasing) during printing, the relationship between the digital matrix and physical substrate is defined by the Resolution equation:

When scaling an image to fit a target paper size while maintaining its Aspect Ratio (AR), the logic follows a conditional system to determine the limiting dimension:

This ensures the image hits the margins without distortion. The final PDF byte size estimation (E) for a collection of n images is approximated by the summation of compressed stream sizes plus the PDF object overhead (O):
