PdfZap: Free Online Batch PDF Compression Tool 95

PdfZap is a free, simple, and secure online tool for batch PDF compression, which can process files in the browser, guaranteeing document quality while achieving good compression results.

Features

• Local Processing: File processing is completed locally in the browser, not uploaded to any server—zero uploads, zero storage—ensuring your privacy and security.

• Batch Processing: Multiple PDF files can be processed at once, and compressed files are automatically packaged for download after completion, saving time and improving efficiency.

• Multiple Compression Modes: Three modes—Maximum Compression, Balanced Mode, and Lossless Compression—offer flexible options based on your needs.

• Easy to Use: Just open the webpage to use it; no registration or login required, convenient and fast.
