Reduce PDF file sizes significantly while maintaining document quality with our advanced compression tool. Using Deflate (ZIP) lossless compression technology, your text content remains 100% intact, selectable, and copyable. Perfect for email attachments, web uploads, and storage optimization without sacrificing document integrity.
Customize your compression with flexible settings designed for different needs. Choose image quality levels from low to maximum to balance file size and visual quality. Optional metadata removal further reduces file size while enhancing privacy. The grayscale conversion option provides additional size reduction for documents where color is not essential.
Our tool uses industry-standard Deflate compression, the same algorithm used in ZIP files. Unlike lossy compression methods, this approach preserves all text data perfectly. Your compressed PDFs maintain full searchability and text selection capabilities, making them ideal for professional and archival purposes.
Your sensitive documents stay completely private during compression. All processing occurs locally in your browser - no files are uploaded to external servers. You maintain full control over your data while benefiting from powerful compression technology. No account registration or software installation required.
Compression results vary based on the PDF content. Image-heavy PDFs can typically be reduced by 50-80%, while text-based documents may see 10-30% reduction. Our tool shows exact before/after sizes.
We use lossless Deflate compression for text content, so text remains 100% intact and searchable. For images, you can choose quality levels to balance file size and visual quality based on your needs.
Yes! All compression happens locally in your browser. Your files are never uploaded to any server, ensuring complete privacy for sensitive documents.
Metadata includes information like author name, creation date, and software used. Removing it can reduce file size slightly and enhances privacy by stripping identifying information from your PDF.
Our tool works with unprotected PDFs. If your PDF is password-protected, you'll need to remove the protection first before compressing.
