FAQ
Questions people ask before trusting a tool
How does the PDF Compressor work without uploading?
Everything runs directly in your browser. We load the PDF structure and optimize page streams using Javascript so your data remains completely private.
Can I really compress a PDF to 100KB?
Yes. If your document contains large images or metadata, we downscale them to hit your target size of 100KB, 200KB, or 500KB.
Will my PDF lose text quality?
No. Vector text, fonts, and layout structures remain fully intact. Only high-resolution graphics are optimized.
Is there a page limit?
No. You can compress PDFs of any page length, completely free.
