Core Features

100% local, zero upload, full privacy. Everything runs inside your browser.

1. 100% Local Privacy Compression

All parsing, compression, and rendering happen locally in your browser. No file data is ever transmitted to any server.

2. Three Compression Modes

• Light — Almost lossless quality for formal documents
• Balanced — A balanced quality/size ratio for daily use
• Extreme — Maximum size reduction for uploading

3. Batch Processing

Upload multiple PDFs at once, process them in parallel, and download individually or as a single ZIP file.

4. Large File Support

Supports PDFs up to 100MB per file, enough for high-resolution scans and long multi-page documents.

5. Cross-Device Compatible

Works on desktop, tablet, and mobile. No app installation needed.

6. Smart Memory Management

Built-in memory optimization prevents crashes and keeps performance smooth even with large files.

The other five tools

Compression is one part of this site. The rest handle different jobs under the same rule: the file stays on your device.

• Merge PDF — combines up to 20 files into one, keeping the original page order.
• Split PDF — splits by every page, every N pages, or a custom range list.
• PDF to JPG — renders each page to an image at 72, 144 or 216 dpi.
• Redact PDF — draw a box, check how many characters are still copyable inside it, then flatten the page and check again.
• Remove PDF metadata — shows the Info dictionary and the XMP packet before deleting them, so you can see what was attached.
