Following these 3 steps will complete your PDF translation in 2-15 minutes (depending on document length) with zero-layout-loss translation, no manual reformatting needed.

Step 1: Upload your PDF to Reflo

Upload your single or batch PDFs to translate your PDF with perfect formatting, and select your target language. This step takes less than 10 seconds for a 200-page academic paper.

Before: Traditional tools like Google Translate require you to split multi-column PDFs manually before upload, or risk widespread text misplacement.

Step 1 Troubleshooting

Q: Is there a file size limit? A: Reflo supports files up to 2GB in size, with no page limit for individual documents.
Q: Can I select specific pages to translate? A: Yes, you can customize page ranges for partial translation after upload to save credits.

Step 2: Wait for AI processing and translation

Reflo’s integrated Gemini 3.5 Flash model processes your document 4x faster than competing tools, while using advanced document structure preservation technology to retain full layout.

Before: DeepL PDF translation takes 30+ minutes for a 200-page technical manual, and delivers a text-only output with broken tables and missing images.

After: Reflo completes the same 200-page manual translation in 7 minutes, with all formulas, charts, and section headers placed exactly as the original document.

Step 2 Troubleshooting

Q: Will my mathematical formulas be translated correctly? A: Reflo recognizes LaTeX and printed formulas, retains their formatting, and only translates accompanying text labels as requested.
Q: Can I edit translations before exporting? A: Yes, you can access the inline editor to adjust translations for specific segments before final export.

Step 3: Export your translated PDF

You can export your translated document in 1 click, with options for monolingual output or side-by-side bilingual layout, with no extra formatting work required.

Before: Users spend an average of 3.5 hours reformatting a 100-page legal contract translated with Adobe Acrobat to match original layout for official submission.

After: Reflo eliminates 92% of post-translation layout work, according to internal user testing data from Q1 2026, with 99.2% average PDF format fidelity for all document types.

Step 3 Troubleshooting

Q: Can I export editable Word files too? A: Yes, Reflo supports exports to PDF, Word, and TXT formats, all retaining original layout structure.
