About Local File Compressor
Name: Local PDF Compressor: Reduce Size (Till 500MB)
Summary: Intelligently compress PDF, DOCX, PPTX, and XLSX files locally. Reduce file size without losing quality. Privacy-first.
Description:
The Local PDF Compressor is a smart, privacy-focused tool designed to reduce the file size of your documents directly in your browser. Unlike other tools, your files are processed locally on your device—they are never uploaded to a server.
KEY FEATURES:
1. Intelligent PDF Compression
Smart scaling engine that balances quality and file size.
Detects if a file is already optimized to prevent accidental size increases.
Supports files up to 500MB.
2. Multi-Format Support
Compress not just PDFs, but also Office documents.
Supports: PDF, PPTX (PowerPoint), DOCX (Word), and XLSX (Excel).
3. Batch Processing
Select multiple files at once.
The tool processes them individually and downloads them automatically.
4. App Mode (Window View)
Click the "Detach" icon to open the compressor in its own dedicated window.
Works like a standalone desktop application.
5. Privacy First
100% Local Processing.
No cloud uploads, no API keys, no data collection.
Powered by advanced local libraries (PDF-Lib, JSZip).
PRIVACY & SECURITY:
This extension operates entirely offline. It uses your browser's resources to compress files. We do not view, store, or transmit your documents.
In each option of compression, if it can not compress more, it will show 0 compress and doesn't change. If it can compress, it shows the original name of the file and _compressed at the end of the name of the file.
Note: This extension is free to use and supported by optional donations.
