Compress PDF

About PDF Compressor

This tool compresses PDF files to reduce their file size. You can choose from different compression levels to balance between file size and quality. All processing happens in your browser for complete privacy.

How does PDF compression work?

PDF compression reduces file size by optimizing images, removing unnecessary metadata, and applying compression algorithms. This tool re-encodes the PDF content with optimized settings to achieve smaller file sizes.

What compression levels are available?

You can choose from Low (better quality, larger file), Medium (balanced), or High (smaller file, lower quality). Medium compression offers the best balance for most use cases.

What is the file size limit?

The maximum file size is 50MB. This ensures smooth performance in your browser. For larger files, consider using desktop PDF software.

Will compression affect PDF quality?

Compression may slightly reduce image quality, especially at high compression levels. Text and vector graphics typically remain sharp. Preview the result before downloading to ensure it meets your needs.

Can I preview the compressed PDF?

Yes! After compression, you can preview the compressed PDF before downloading. You can also use fullscreen mode for better viewing.

What if the file size does not reduce?

Some PDFs are already well-optimized and cannot be compressed further. Text-only PDFs or PDFs with already-compressed images may see minimal size reduction.

Is my PDF file safe?

Absolutely! All PDF compression happens directly in your browser. Your PDF file is never uploaded to any server. Everything stays private on your device.

Can I compress password-protected PDFs?

Currently, this tool does not support password-protected or encrypted PDF files. Please remove the password protection before compressing.
