FAQ
How much can the file size be reduced?
Compression results vary depending on the PDF content. Files with many images typically see larger reductions. Text-heavy PDFs may see modest reductions since text is already compact.
Will compression affect the quality of my PDF?
The tool optimizes the PDF structure and metadata. Lower quality settings apply more aggressive optimization. For most documents, the visual difference is minimal.
Is there a file size limit?
There is no strict limit, but very large files (100MB+) may be slow to process since everything runs in your browser. For best performance, process files under 50MB.
Are my files uploaded to any server?
No. All compression happens entirely in your browser. Your files never leave your device.
What is the difference between Low, Medium, and High quality?
Low quality applies maximum compression for the smallest file size. Medium balances size and quality. High quality preserves most detail with lighter compression.
