Keep formulas, figures, tables, section headings, references, and dense two-column layouts readable after translation.

Translated and bilingual PDFs

Download a clean translated PDF for reading, plus a bilingual PDF when you want to compare the translation with the original paper.

LLM-powered translation

Switch between multiple large language models and translation engines to balance speed, cost, and translation quality for different research papers.

Batch paper translation

Upload and translate multiple academic PDFs in one workflow, then track each paper independently until the translated files are ready.

Online PDF preview

Preview translated and bilingual PDFs in the browser before downloading, so you can quickly check formulas, figures, tables, and page layout.

No content stored

Your uploaded papers and translated results are used only for the translation task and are not kept as a content library or reused for training.

Highlight 01

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.
