Frequently asked questions
Questions about this tool
How can I compress a PDF without losing quality?
Choose the high-quality or balanced setting. Some image recompression may still occur, so check the downloaded document before sending or printing it.
Why did my PDF only become slightly smaller?
The source may already be compressed, or most of its size may come from content that cannot be reduced without visible quality loss.
Which compression level should I choose?
Use high quality for print, balanced for ordinary sharing, and maximum compression when meeting a strict file-size limit matters most.
Does compression remove PDF pages?
No. Compression is intended to optimize the existing document, not delete selected pages.
