Frequently Asked Questions (FAQs)

Will my PDF text quality be degraded?

No. Our optimization engine targets background raster images and redundant document metadata while maintaining sharp text vectors.

Is it safe to compress confidential documents here?

Yes. All operations occur 100% locally in your client web browser memory using WebAssembly and Javascript engines.

Why did my file size not decrease significantly?

If your PDF already consists mostly of plain text or previously optimized JPEG images, further compression may be minimal.
