Common Questions
Everything you need to know
How do I compress a PDF file?
Upload your PDF using the button above, choose your preferred compression level, and click compress. Your smaller PDF will download automatically.
Will compression affect my PDF quality?
Our compression optimizes images and removes unnecessary data while preserving text clarity. The 'Print' preset maintains the highest quality, while 'Web' achieves maximum compression.
How much can I reduce my PDF file size?
Depending on the content, you can reduce file sizes by up to 90%. PDFs with many images see the biggest reductions.
Is there a file size limit?
No server-side limits since everything processes in your browser. Very large files may take longer to process depending on your device.
Is my PDF secure during compression?
Yes, completely. Your files never leave your device—all compression happens locally in your browser. We don't upload or store anything.
