A research-paper translation can help you understand an unfamiliar field or language. It should not become a substitute for the original when you quote a result, interpret a formula, or prepare a formal submission.
Treat the PDF as evidence with structure: the claim in the abstract, the conditions in the methods, the numbers in the table, and the limitations in the discussion must still refer to one another after translation.
Identify the field and the kind of translation you need
Before uploading, record the paper's title, authors, source, and version. Decide whether the result is a private reading copy, material for a group discussion, or text intended for submission. These uses require different levels of language and subject review.
Choose a short list of terms that genuinely affect understanding. Give their field and preferred equivalents in the translation instructions. For example: “This paper concerns causal inference in economics.
Keep abbreviations connected to their definitions. A familiar abbreviation can mean something different in another discipline, so do not expand it from memory. Preserve an unresolved term with a note rather than assigning a confident but unsupported meaning.
Check the PDF before asking it to change language
Before translating, test-copy a passage from the main text and another from a page with a more complex layout. While single-column sections like abstracts usually copy cleanly, text flow in multi-column sections, footnotes, or scanned appendices may become scrambled. If the pasted text is out of order, fixing the reading order before translation helps prevent distorted output caused by jumbled input.
For a scan, check that letters, small symbols, and note markers are legible. The OCR and translation workflow explains why recognition problems should be separated from language problems.
If you downloaded from arXiv, retain its identifier and version. The arXiv translation guide covers that source-specific preparation; the workflow here applies to PDF papers more generally.
Choose an output suited to the next task
Upload the file to PDF Craft and select the output you need. PDF output is a translation route. EPUB or Markdown can be used for converted content; enable translation and choose the target language when you also want another language.
Use Markdown when you will edit passages or build research notes. Use EPUB for continuous reading with adjustable text. Keep the original PDF for page-based citations and complex visual material. These outputs do not promise identical pagination.
Add instructions before confirming the task. When processing finishes, download the result and retain it separately from the source. Check Pricing for current usage charges rather than estimating the cost from the PDF's file size alone.
Review equations, tables, and conclusions together
Start with a result that matters to your reading. Trace it through the abstract, the relevant table or figure, and the discussion. Confirm that its population, conditions, and limitations remain the same.
Check numbers with their units and labels. A value without its denominator, comparison group, or confidence interval may no longer express the same finding. Inspect mathematical indices, signs, and equation references against the original image, not merely the rendered translation.
When reviewing figures and tables, examine in-image labels, captions, and in-text citations together, noting any spots that need additional translation or clarification. In densely formatted sections, pay close attention to how multi-column paragraphs connect and whether equations still align with their explanations.
The technical OCR checklist provides a closer inspection method. Use subject expertise when the expression or claim remains uncertain; a translation system is not a scientific validation service.
Keep references and appendices in scope
Check the paper's final sections, not just the main argument. Appendix definitions, supplementary assumptions, and data notes may limit a claim presented earlier.
Preserve author names, years, identifiers, URLs, and edition-specific page references so that the cited work remains findable. Follow the required citation style if you need to provide translated titles or quotations. Do not invent localized bibliographic details.
When formally citing references in academic writing, cite the original source paper in its primary language, noting the source of any translation or specifying that it is your own. Before submission, adjust citation formats and translation requirements according to your target journal's style guide.
Save the source PDF, the unedited export, your term decisions, and the reviewed copy together. That record lets a later reader distinguish what the authors wrote from what recognition, translation, and editing changed.
