01 — Respects your document

Most translators flatten a PDF. We rebuild it.

PDFPal parses your file into an intermediate representation that separates the visual layout from the text. Our AI translates with formulas masked, then re-anchors the translation onto the original layout and rescales each paragraph to fit.

01
Headings & multi-column flow
Reading order is detected and kept, column by column.
02
Tables & figures
Cells, captions and figure anchors stay in position.
03
Equations, verbatim
Math is masked as placeholders and never translated.
04
Footnotes & page numbers
Marginalia and pagination map one-to-one.

Loved by researchers

I used to spend an afternoon reformatting a translated paper. PDFPal hands it back looking exactly like the original — tables, equations and all. I just read it.

The equations survive. That alone saves me from re-typing every formula by hand after a machine translation.

Arjun Mehta
PhD candidate · applied maths

I read German case law in English and the footnotes, numbering and margins all stay put. It simply looks right.
