Your PDF never leaves your device. All compression is done locally using modern browser APIs. No data is sent to any server —ever.

Compression happens instantly in your browser. No waiting for server processing —even large PDFs compress in seconds.

Choose the right balance for your needs —from minimal compression for quality-critical documents to maximum compression for email and web sharing.

Significantly reduce your PDF file size while preserving readability. Perfect for email attachments, cloud storage, and faster page loads.

• Use Low compression for documents with fine text or detailed graphics to preserve quality.
• Medium compression is ideal for most office documents, reports, and presentations.
• Use High compression when file size is the top priority —great for email attachments.
• PDFs with lots of images benefit most from compression. Text-only PDFs are already quite small.
