Our smart compression algorithms are designed to minimize quality loss. Light compression preserves nearly all original quality, Balanced compression maintains good quality with noticeable size reduction, and Maximum compression optimizes for smallest file size with some quality trade-offs. Text remains crisp and readable in all compression levels.

You can compress PDF files up to 100MB in size. This covers most standard documents, presentations, and reports. For larger files, consider splitting them into smaller PDFs first, then compressing each part individually.

No software installation required! Our PDF compressor works entirely in your web browser using advanced web technologies. Simply open the page, upload your PDF, and start compressing. Compatible with Chrome, Firefox, Safari, Edge, and all modern browsers.

Currently, our compressor works best with unprotected PDF files. If you have a password-protected PDF, you'll need to remove the password protection first before compression. After compression, you can re-apply password protection using other PDF tools.
