How Our Image to PDF Converter Handles Scaling & Math

To ensure your images do not stretch or distort when placed onto a standard A4 or US Letter PDF page, our tool relies on strict aspect ratio calculations. Scaling an image proportionally involves calculating a ratio for both width and height, then automatically applying the smaller mathematical value to the final render. Furthermore, our core PDF engine applies intelligent compression algorithms to drastically reduce the output file size without sacrificing noticeable visual quality.
