What is a PDF compressor?
A PDF compressor reduces the file size of a PDF by re-encoding its content and stripping unnecessary metadata.
Is it free?
Yes. Our PDF compressor is free. No signup or registration required.
Are my files secure?
Yes. Compression happens in your browser. Your files never leave your device.
What is the file size limit?
The maximum file size is 50 MB.
How does the compression work?
The tool re-encodes the PDF structure and strips metadata like author, title, and creation date to reduce size.
How much can the file size be reduced?
Results vary depending on the PDF. Already-optimized files may not shrink further. The tool will display "Already optimized" in that case.
Does compression affect quality?
No. The compression preserves all pages, text, and images. Only metadata is removed.
What if the PDF is already compressed?
The tool will show an "Already optimized" message if the file cannot be made smaller.
What format is the output?
The result is a single compressed PDF file that you can download.
Do I need to install anything?
