Compress PDF to Reduce File Size
Free & private · no signup · no watermarks · files deleted in 24 hours
Need to reduce your PDF file size for email, uploading, or storage? Our Compress PDF tool intelligently reduces file size by optimising embedded images, removing redundant objects, and streamlining the file structure — all while preserving readable text and acceptable visual quality. Choose from three presets: Screen for maximum compression ideal for web use, Ebook for a balanced quality-size trade-off, or Printer for minimal compression when high-quality output matters most.
Image-heavy PDFs typically see reductions of 60-80%. Scanned documents, reports with photos, and design files benefit most. Text-heavy PDFs compress less dramatically but still produce smaller, more efficient files. Processing happens on our secure Hetzner server and your file is deleted within one hour.
Key features: Three compression presets • Optimises images and file structure • Maintains readable text quality • Works on PDFs up to 100MB • 256-bit SSL during transfer • No watermarks or registration

Frequently Asked Questions About Compress PDF
Everything you need to know about our Compress PDF tool
Yes, completely free. Our Compress PDF tool has no hidden costs, no watermarks, and no registration requirement. You can process as many files as you need, each up to 100MB, at no charge. We believe professional PDF tools should be accessible to everyone — students, freelancers, and businesses alike.
Your files are fully protected. All uploads and downloads use 256-bit SSL/TLS encryption during transfer. Processing happens on our isolated Hetzner server infrastructure in Germany — your file is never shared, analysed for commercial purposes, or stored longer than necessary. Every uploaded and processed file is automatically and permanently deleted within one hour of processing.
Supported file types: This tool accepts PDF files up to 100MB each. For files larger than 100MB, use our Compress PDF tool first.
Portable Document Format
Yes — works on any device. The interface is fully responsive and tested on desktop, tablet, and mobile. Touch-friendly upload areas, drag-and-drop support on desktop, and mobile-optimised buttons mean you get the same experience whether you are on a MacBook, an iPad, or an Android phone. No app download is ever required — open your browser and go.
Choose based on how the file will be used. Screen applies aggressive compression for web sharing or email — typical reductions are 60-80% for image-heavy PDFs. Ebook balances size and readability — ideal for digital reading on tablets and phones. Printer minimises compression to preserve print quality — best when the PDF will be commercially printed. Text-only PDFs compress less dramatically regardless of the preset chosen.
