History
Reopen finished translations from History while the file is still available.
Academic PDF translation that keeps every pixel
Translate PDF Online helps researchers and teams convert scholarly PDFs between languages without breaking columns, equations, tables, or figures. Our pipeline is tuned for dense academic layout, not plain text dumps.
Many language pairs are available in the UI. Use the History column to reopen recent uploads and translation jobs without uploading the same PDF again.
