Technical Framework & Principles

Breaking the Limitations of Traditional Cloud Document Tools

Standard translation engines extract scanned text into a messy, single-column plain text wall. GoLocalPDF utilizes structural coordinate repainting, offline OCR, and geometric layout analysis to ensure that original columns, tables, images, and text alignments are strictly preserved. This lossless document reconstruction and multi-column layout analysis guarantees that parallel translation retains the exact side-by-side reading layout without ruined coordinates.

Frequently Asked Questions

Q:How does it preserve the scanned layout?

By performing layout analysis and spatial coordinates grouping before translating text nodes, then stamping them back.

Q:Is my scanned data secure?

Yes. All files are processed client-side in your browser. We never transfer documents to our servers.
