🎨🗜️ PDF Compressor

PDF compression reduces file size by optimizing images, removing redundant data, and compressing text without losing quality. Our tool uses advanced algorithms to analyze your document and apply the most effective compression techniques. All processing happens in your browser, ensuring your files never upload to our servers for complete privacy and security.

We offer three compression levels: Low compression maintains maximum quality with moderate size reduction (10-30%), Medium compression balances quality and file size (30-60% reduction), and High compression provides maximum size reduction (60-90%) with minimal quality loss. The best choice depends on your specific needs and intended use.

Our compression algorithm is designed to preserve text quality completely while smart-compressing images. Text remains crisp and fully searchable. For images, we use advanced techniques that maintain visual quality while reducing file size. Low and medium compression levels preserve image quality excellently, while high compression may show minimal quality reduction.

There's no strict file size limit for PDF compression, as processing depends on your browser's capabilities. However, for optimal performance, we recommend compressing files under 100MB. Very large files may take longer to process and require more memory, so consider your device's capabilities when working with large documents.

Password-protected or encrypted PDF files cannot be compressed until they are unlocked. You'll need to remove the password protection first using the original password. Once unlocked, you can compress the PDF normally using any of our compression levels. This security measure ensures that protected content remains secure.

Compression results vary depending on your PDF's content. PDFs with many images typically compress better (50-90% reduction), while text-heavy documents may see smaller reductions (10-40%). Our tool provides real-time estimates before compression, so you can see expected results. Most users achieve 30-70% file size reduction while maintaining excellent quality.

Our compression process preserves essential PDF features including metadata, bookmarks, hyperlinks, and form fields. We focus on optimizing file size through image compression and data restructuring without removing functional elements. All interactive features and document properties remain intact in the compressed version.

Yes, our PDF compressor is completely free to use with no hidden costs, watermarks, or registration requirements. You can compress up to 20 PDF files at once using all available compression levels without restrictions. There are no limits on file size (within browser capabilities) or the number of compressions you can perform.

Yes! You can upload up to 20 PDF files at once for batch compression. All files are automatically compressed as soon as you upload them, using your selected compression level. This makes it easy to process multiple documents quickly and efficiently, saving you time and effort.

Our PDF compressor works on all modern devices and browsers including Chrome, Firefox, Safari, and Edge on Windows, Mac, Linux, iOS, and Android. The tool is responsive and optimized for both desktop and mobile use. As long as your browser supports modern JavaScript, you can compress PDFs from any device with an internet connection.
