Privacy-Focused Browser Tool Compresses PDFs Locally Without Uploading Sensitive Documents

A developer created a PDF compression tool that runs entirely inside the browser to protect sensitive personal and professional documents from third-party servers. The solution addresses repeated situations where embassy submissions, financial presentations, contracts, and internal reports exceeded size limits, forcing users to choose between installing desktop software or risking data exposure through online services. The tool reduces scanned and photographic PDFs by 66 to 97 percent depending on quality settings while honestly reporting weaker performance on text-heavy files compared with Ghostscript. It works on both desktop and mobile platforms, including iPhone and Android, requires no installation, and continues functioning offline after the first page load. On mobile devices the application respects memory constraints by limiting images to four megapixels, preserving readability for A4 documents intended for printing. The project originated from a single evening script built around Ghostscript and evolved into a full web application after similar compression needs recurred across multiple devices and locations.
