FAQ
How does PDF compression work?
We rebuild your PDF with optimized structure, object streams, and optional metadata removal to reduce file size.
Will compression affect text quality?
Text and vector content stay sharp. Image-heavy PDFs see the biggest size reduction.
Is my PDF uploaded to a server?
No. Compression runs entirely in your browser.
