1. Selective Image Downsampling: Most oversized PDFs are caused by uncompressed 300+ DPI scanned images or high-resolution photos embedded within the document. The compression engine resamples embedded raster graphics to an optimal DPI matching standard web display parameters (72–150 DPI).
2. Color Depth Optimization: Reduces redundant 24-bit color information in text documents to standard grayscale or optimized 8-bit palette channels, shrinking file weight without affecting letter clarity.
3. Client-Side Security: Processing takes place within the browser's sandbox environment. No tokens, documents, or personal credentials leave your local device.

Yes, 100%. Unlike conventional PDF websites that upload your files to remote cloud servers, this tool runs entirely inside your device's web browser using client-side Web APIs. Your confidential files never touch our servers or the internet.
Legacy applicant tracking systems (ATS), university portals, and government web systems (e.g. CRA My Account, IRCC, provincial court registries) set strict file size caps (such as 200KB or 2MB) to conserve database bandwidth and maintain fast bulk processing speeds.
