Yes, absolutely! All PDF processing happens locally in your browser. Your files never leave your device and are not uploaded to any server. This ensures complete privacy and security for your documents.

You can compress PDF files up to 50MB. For optimal performance and faster processing, we recommend files under 30MB. Larger files may take more time depending on your device’s specifications.

It depends on the compression level you choose:

Low Compression: Minimal quality loss, small size reduction

Medium Compression: Balanced quality and size reduction

High Compression: Maximum size reduction, noticeable quality reduction

We recommend trying different levels to find the best balance for your needs.

Our tool can compress most PDF files including:

• Text-based PDFs (best results)

• Image-heavy PDFs (photos, scans)

• PDFs with embedded fonts

• Multi-page documents

• Password-protected PDFs (must be unlocked first)

Compression time depends on several factors:

• File size (larger files take longer)

• Compression level (high compression takes more time)

• Your device’s processing power

• Number of pages in the PDF

As a general guideline, a 10MB PDF typically takes 10-30 seconds to compress on most modern devices.

Currently, this tool processes one PDF file at a time. For batch processing multiple PDFs, you need to compress them individually. We’re working on adding batch compression features in future updates.

Yes! The PDF Compressor is fully responsive and works on all modern browsers including:

• Mobile phones (iOS & Android)

• Tablets

• Desktop computers

• Laptops

For best performance on mobile devices, we recommend using files under 20MB.

No, there are no limits! You can compress as many PDFs as you need, completely free. Since all processing happens locally on your device, there are no server costs or usage restrictions.
