Page parity

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.

Headings & multi-column flow

Reading order is detected and kept, column by column.

Tables & figures

Cells, captions and figure anchors stay in position.

Equations, verbatim

Math is masked as placeholders and never translated.

Footnotes & page numbers

Marginalia and pagination map one-to-one.

Community-made earthquake shaking maps — Original (EN) — Page one of a public USGS fact sheet, before and after. Both columns, the color-coded intensity table, the map and its caption all land exactly where they started.

Same page, three ways. Only one keeps the layout.

✓headings still read as headings

Every excerpt is verbatim. The middle column is real text extraction of the same page — the reading order is already wrong before a single word is translated. See the full document →

The same page. A different language.

No mock-up: on the left, page one of a public Congressional Research Service brief. On the right, the file PDFPal handed back — same two columns, same chart, same margins. Open the full document and check it yourself.

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.

Dr. Lena Fischer

Neuroscience · reads 10+ papers/wk

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.
