Frequently Asked Questions

Does cropping reduce the resolution of textbook diagrams or formulas?

No. Cropping only resets the visible display box; underlying image and text vector data are preserved at 100% original quality.

Is my unpublished academic dissertation or manuscript kept private?

Yes. Zero data leaves your computer. Unpublished books and research papers stay entirely in local browser memory.

Can I apply different margins for even and odd (duplex) pages?

Yes. You can fine-tune crop borders per page or apply symmetric margins across facing spreads.
