FAQ

Reduce PDF Size — Common Questions

Everything you need to know about compressing a PDF file online for free.

Can I reduce PDF size for free?
Yes. This tool is completely free to use online. Upload your PDF, choose a compression level, and download your smaller file with no charges or account required.
Will quality be lost during compression?
Using Balanced or Lossless mode, quality loss is minimal and often unnoticeable for text-based PDFs. Strong Compression reduces quality more in exchange for a much smaller file size.
Do I need to install software?
No. This PDF compressor works entirely inside your browser. There is nothing to install, no plugins, and no extensions required on any device.
Can I choose how much to compress?
Yes. Choose from three levels: Lossless for maximum quality, Balanced for a good mix of size and quality, or Strong Compression for the smallest possible output file.
Can I compress multiple PDFs at once?
Yes. Upload as many PDF files as you need. Each one is compressed individually and available as a separate download once processing is complete.
Are my PDF files secure?
Completely. Your PDF files are processed only in your own browser and are never sent to any server. Nothing is stored, logged, or shared at any point.
