Frequently Asked Questions
Common questions about PDF compression
How does the compression work?
We remove unnecessary metadata (like author, creator tags) and optimize the internal object streams of the PDF structure.
Will my text become blurry?
No. Our optimization focuses on structure and metadata, not aggressive image downsampling, so text remains crystal clear.
Is there a file size limit?
No software limits. Since it processes in your browser, performance depends on your device's memory.
Does it work on Mac?
Yes, it works on Mac, Windows, Linux, and even mobile devices directly in the browser.
Can I compress password protected PDFs?
You must unlock the PDF first. For security reasons, we cannot process encrypted files without the password.
How much space will I save?
It varies by file. Text-heavy PDFs often see 10-50% reduction. Already optimized files may not change much.
