Highlight 1
Read foreign-language papers without breaking the PDF
General translators often flatten a paper into plain text. PDFTrans keeps the document as a PDF, so equations, diagrams, tables, captions, references, and page flow stay close to the original while the content becomes easier to read.
Highlight 2
Compare the translation with the original paper
Use the bilingual PDF to verify technical terms, equations, citations, and section context while you read. It is especially useful for dense journal articles, arXiv papers, theses, and technical reports.
Highlight 3
Translate paper collections in one workflow
Upload several papers, choose your preferred model or translation engine, and let PDFTrans process each file as a separate task. Preview results online, then download the translated PDFs when they are ready.
