Frequently Asked Questions
Does PDF compression reduce quality?
Our compression algorithm optimizes the PDF while maintaining the best possible quality. High compression may slightly reduce image quality for very large images.
Is my file uploaded to a server?
No! All PDF compression happens directly in your browser using JavaScript. Your files never leave your device.
What types of PDFs can be compressed?
All standard PDF files can be compressed. PDFs with many images typically achieve the best compression results.
Is there a file size limit?
PDFEasyHub handles files up to 100MB. For larger files, consider splitting them first using our Split PDF tool.
