Private File Reducer — compress PDF, Office & images locally

Overview

Compress PDF, Word, PowerPoint, Excel and images — 100% in your browser. Private File Reducer shrinks the size of your files before you email or share them. Unlike the usual online compressors, your files NEVER leave your device: there are no servers and no uploads. All compression runs locally in your browser. WHAT IT COMPRESSES • PDF — reduces the embedded images while keeping text selectable, with a "maximum" mode that rasterizes scanned documents for the smallest size. • Word, PowerPoint and Excel, including macro-enabled files, plus OpenDocument and EPUB — the images inside are recompressed without changing the layout. • Photos and graphics in the common web and camera formats, converting each to whichever result is smallest while preserving transparency. • SVG vector files, with safe minification. WHY IT'S DIFFERENT • 100% local — nothing is uploaded, works offline. • No access to your browsing — it cannot read your tabs, history or websites. (Dragging results into sites like Gmail or Drive is OPT-IN: you enable it explicitly, and it can be turned off anytime.) • No account, no ads, no tracking. • Drag & drop files or entire folders, see original → final size and % saved, download individually or all in a ZIP. • "Target size": compress until it fits under 25/10/5 MB — perfect for email attachment limits. • Simple quality control and light/dark theme. Free: one file at a time, basic compression. Pro (one-time payment): batch processing, ZIP download, maximum compression and target size (fit under X MB).
