Frequently Asked Questions

Is this PDF compressor free?
Yes, completely free. There are no hidden charges, no sign-up required, and no limits on how many PDFs you compress.
Is my PDF safe? Does it get uploaded?
Your PDF never leaves your device. All compression happens locally in your browser using JavaScript. No files are sent to any server.
How does the compression work?
Each page of your PDF is rendered at an optimized resolution, then re-assembled into a new PDF with compressed image quality tuned to meet your target size. This approach is highly effective for reducing PDF file sizes.
Can I compress to an exact file size?
We use an iterative algorithm to get as close as possible to your target size. The final result may be slightly under the target β€” never over β€” to ensure compatibility.
What is the maximum PDF size I can compress?
There is no strict limit. However, very large PDFs (50MB+) may take longer to process since all work is done in your browser. For best performance, files under 20MB are recommended.
Will the PDF text still be selectable after compression?
The compressed PDF is image-based, meaning text may not be directly selectable. If selectable text is critical, use a higher target size for better fidelity.
