Frequently Asked Questions

Will I lose text formatting or image quality?

No. Our tool focuses on optimizing the PDF's internal catalog stream structure and flattening unnecessary elements. It does not aggressively downsample image resolutions, so your documents remain crisp and readable.

Are my documents private?

Absolutely. ToolTari runs natively on your machine's browser memory. Your files are never uploaded or shared.
