FAQ
What does a PDF compressor do?
A PDF compressor reduces unnecessary PDF structure and optimizes the document to potentially reduce its file size.
Is this PDF compressor free?
Yes. The tool is designed to be free to use.
Will every PDF become smaller?
Not necessarily. Some PDFs are already highly optimized. In those cases, there may be little or no additional reduction.
Which compression level should I choose?
Recommended is a good starting point for most users.
Does PDF compression reduce quality?
This browser-based version primarily optimizes the PDF structure. It does not aggressively re-encode embedded images.
Are my PDF files uploaded?
The tool is designed to process the PDF directly in the browser.
Can I compress a large PDF?
The practical limit depends on the PDF size and the visitor’s available browser memory.
