Short answer: For table-heavy PDFs such as financial statements, fee schedules, term sheets and regulatory filings, Bluente is the best choice. It keeps merged cells, column widths and number alignment intact, and it translates tables inside scanned pages. If you can only use free tools, translate the original Word or Excel file instead of the PDF. For very poor scans, ABBYY FineReader can extract tables first.
Tables are where PDF translation most often breaks. Translated text is usually longer than the source; German and French sentences typically run about 30% longer than the English, and short labels can run far longer. Text-first tools push that extra length into fixed cells. The result:
Columns misaligned
Merged cells split apart
Numbers wrapped onto two lines
Headers pushed onto the next page
Quick summary
Best overall for table-heavy PDFs: Bluente
Best for clean, simple tables: DeepL (try a sample first)
Best free option: Google Translate (text-based PDFs only)
Best for extracting tables from scans: ABBYY FineReader PDF
Best workaround: translate the source DOCX or XLSX and re-export to PDF
What "preserving tables" actually means
We checked six things on every output:
Cell structure: merged and split cells survive
Column widths: the table still fits the page
Number formatting: decimals, thousands separators and currency stay correct and aligned
Text fit: longer translations wrap inside cells instead of overflowing
Headers and repeated rows: multi-page tables keep their header rows
Scanned tables: tables in image-based pages are recognised and translated
Test file: Mitsubishi Corporation's 26-page FY2025 earnings summary (Japanese → English), with results tables, a full balance sheet, P&L, cash-flow and equity statements, and segment tables.
Head-to-head test: a 26-page Japanese financial filing
We translated Mitsubishi Corporation's FY2025 earnings summary (a public, table-heavy 決算短信 filing) from Japanese to English with each tool and reviewed every page.

What we found
Bluente: layout, every table and every number intact; company and asset names correct; same 26 pages as the source. One mislabelled profit line and minor cosmetic inconsistencies.
Google Translate: every negative number turned into "ÿ"; page-1 tables collapsed onto single lines; "previous consolidated" translated as "Front coupling"; a share buyback rendered as "acquisition of formula"; watermark on every page.
DeepL: balance-sheet figures shifted a row; tables printed over text; "Global McDonald's" hallucinated in the table of contents; Lawson rendered as "-Son"; the wrong company named as investor in a copper asset; output grew from 26 to 39 pages.
Adobe Acrobat: could not translate the file.
One document and one language pair, so this is an illustrative test, not a benchmark. Scores weight tables and accuracy at 55%, as for any financial filing. [Full test log available on request.]

1. Bluente — Best for table-heavy PDFs
Best for: finance, legal and compliance teams translating reports, schedules and filings.
Why it handles tables well
Document-first engine that rebuilds the layout around the translated text instead of overwriting fixed boxes
Keeps cell structure, column widths and number formats
Built-in OCR recognises and translates tables in scanned pages
Also preserves Excel cell references and number formats, and PowerPoint table layouts
Glossaries keep line-item names consistent across every table
Test results: Scored 93/100 on the Mitsubishi filing. Every balance-sheet figure stayed on its row and every negative stayed negative.
2. DeepL — Good for simple tables, test complex ones
Strengths: fluent text, translates PDFs directly, and can output DOCX on higher paid plans.
Watch-outs: DeepL recommends uploading the source Word or PowerPoint file if PDF results aren't satisfactory. The free plan is limited to 1 file a month.
Test results: Scored 35/100. Balance-sheet figures shifted up a row, tables printed over text, and negatives split across lines.
3. Google Translate — Free, but not for scanned tables
Strengths: free, handles PDFs up to 10 MB and 300 pages.
Watch-outs: text in scanned pages and images is left untranslated, and there's no glossary control.
Test results: Scored 36/100. Every negative figure corrupted to "ÿ" and page-1 tables collapsed onto single lines.
4. Adobe Acrobat AI Assistant — Convenient inside Acrobat
Strengths: translate and then edit the PDF in one place.
Watch-outs: requires a paid AI Assistant plan, and scans need OCR first.
Test results: Could not translate the file.
5. ABBYY FineReader PDF — Best for extracting tables from scans
Strengths: reliable table recognition and export to Excel or Word.
Watch-outs: it doesn't translate. You export, translate the result with another tool and rebuild the PDF, which means three steps instead of one.
Free workflow if your budget is zero
Get the source file. If the PDF came from Word or Excel, translate that file instead.
Test 2–3 representative pages before running the whole document.
Check the worst table first: the widest one with the most merged cells.
Re-export to PDF and compare page by page.
If tables still break, that's the point where a document-first tool pays for itself in reformatting time.
Checklist before you send a translated table
[ ] Every number matches the source
[ ] No cell text overflows or is cut off
[ ] Merged headers are still merged
[ ] Multi-page tables repeat their headers
[ ] Footnote markers still point to the right notes
[ ] Page count is close to the original

FAQ
Which PDF translator keeps tables intact?
Document-first tools like Bluente preserve merged cells, column widths and number formatting. Text-first tools often misalign tables because translated text is longer than the source.
Why do tables break when I translate a PDF?
PDFs store text in fixed positions. When the translation is longer, text-first tools overflow cells or reflow columns. Tools that rebuild the layout around the new text avoid this.
Can I translate a scanned PDF with tables?
Yes, with a tool that has OCR. Bluente recognises and translates tables in scanned pages. Google Translate leaves text in scanned pages untranslated.
Is it better to translate the Excel or Word original?
If you have it, yes. Translating the source file usually gives you more control over cell widths, fonts and page breaks than translating the exported PDF.
What's the best tool for translating financial statements?
For financial statements and annual reports, use a tool that preserves number formats and table structure and supports glossaries for line items. Bluente is built for this.
