PDF Compression FAQs

Does compressing a PDF reduce quality?

PDF compression can affect quality depending on the method used. Lossless compression reduces file size without quality loss, while lossy compression may slightly reduce image quality for greater size reduction. Our tool lets you choose the compression level to balance quality and file size.

What's the best compression for scanned PDFs?

For scanned PDFs (which are essentially images), use OCR (Optical Character Recognition) first to make text searchable, then apply medium compression. This maintains readability while reducing file size significantly.

How much can I reduce a PDF file size?

Compression ratios vary depending on the PDF content. Text-heavy PDFs can often be reduced by 50-70%, while image-heavy files might see 20-50% reduction. Our online compressor shows you the potential reduction before downloading.

Is PDF compression safe for sensitive documents?

When using our online tool, your files are processed securely and automatically deleted from our servers after compression. For highly sensitive documents, consider using offline PDF compression software.
