Frequently Asked Questions

How does PDFPal.ai keep the layout of my document?

PDFPal.ai parses documents into an intermediate representation separating visual layout from text, translates with masked formulas, and re-anchors the translation onto the original layout, ensuring that columns, tables, figures, and reading order stay intact.

How is the pricing structured on PDFPal.ai?

Pricing is per page, with one credit equaling one translated page for standard engines and two credits for premium engines. Free accounts receive 20 pages on sign-up, and paid subscriptions add larger monthly allowances.

Are scanned or image-based PDFs supported?

PDFPal.ai offers a dedicated mode for scanned or image-based PDFs to keep output clean, but does not currently provide OCR (text recognition).

Is my data secure when using PDFPal.ai?

Documents are processed on isolated workers, stored privately, only shared via short-lived signed links, and are never used for model training.
