Technical Insight: Compiling Images into PDF Streams

When images are added, our script reads their dimensions and data streams using the browser's FileReader API. We initialize a new PDF document using the pdf-lib engine. For each image, we convert the raw data into JPEG or PNG image representations inside the PDF wrapper. We then add a blank page corresponding to the selected sheet dimensions (e.g., A4 is 595.27 x 841.89 points). The image is drawn onto the page, scaling its width and height proportionally to fit within the margins. Finally, the page structure is written into a binary buffer, creating a standard PDF download link. The entire process takes place in milliseconds and keeps your files safe.
