Your photos and personal document scans are never sent to remote cloud servers, guaranteeing 100% security for your sensitive personal data.

Direct Stream Embedding without Transcoding

For JPEG images, WebPixa extracts raw DCT-compressed byte streams and injects them directly into PDF XObject image dictionaries without re-encoding. This preserves 100% of the original photo quality and executes in milliseconds.

Adaptive MediaBox Aspect Ratio Scaling

Each PDF page dimension is dynamically calculated to fit standard A4 or US Letter ratios, or scaled to match the exact natural aspect ratio of the source image to prevent cropping or distortion.

Mathematical Calculation Formula & Logic
