Private File Reducer — compress PDF, Office & images locally

About

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).
