よくある質問
Will compressing my PDF make the text blurry or unreadable?
No, the compression algorithm focuses on optimizing image streams and cleaning redundant metadata. Text fonts and vector geometries are preserved, keeping them crystal clear.
Does PDFVoid store any of my compressed files?
Never. PDFVoid is a static web app. The file compression occurs within your local browser sandbox. No file data is sent to our servers.
Can I choose the compression level?
We apply a balanced optimization level that achieves maximum file size reduction while maintaining professional visual fidelity.
