The Problem: PDFs often contain hidden high-resolution images, unused fonts, and invisible layers that bloat the file size.

Our Solution: By safely rendering each page to an image and strictly compressing those images using advanced Web Workers, we guarantee a massive file size reduction.

⚠️ Important Limitation: Because the final PDF is composed of compressed images, the text will no longer be selectable or searchable.
