Bengali Document Translator — English ↔ Bengali

Upload a PDF, Word file, or photo of a document and get an English-to-Bengali translation in minutes — or turn a Bengali দলিল (deed), certificate, transcript, or report into clear English. Poly Translator reads the Bengali script directly, including scanned pages and PDFs set in legacy Bijoy fonts that turn into gibberish when you try to copy-paste them. Both directions work: English → Bengali and Bengali → English.

How Bengali documents come out

Bengali is written left-to-right in the Bengali–Assamese script, an abugida where most letters hang from a horizontal headstroke called the matra (মাত্রা). Two things make Bengali documents harder to process than they look. First, consonant clusters fuse into conjunct ligatures (যুক্তাক্ষর) — ক্ষ, হ্ম, ন্ত্র — whose shapes can differ sharply from their component letters, and some vowel signs are written before the consonant they follow (কে is e-kar + ka, in that visual order). Naive text extraction and cheap OCR mangle both. Second, a huge share of Bangladeshi PDFs — government forms, court filings, newspaper archives — were typeset in Bijoy/ANSI encoding with fonts like SutonnyMJ rather than Unicode, so the underlying text is scrambled even though the page displays fine; we treat those pages visually, like a scan, instead of trusting the broken text layer. Expect Bengali numerals (০১২৩৪৫৬৭৮৯) alongside Latin ones, the daṛi (।) as the full stop, lakh/crore digit grouping (১,২৩,৪৫,৬৭৮), and the taka sign (৳) in Bangladeshi financial documents. Our output is clean, modern Unicode Bengali (or English) as text and HTML with a PDF download — deliberately not a pixel-perfect replica of your original layout, because a rebuilt layout with broken conjuncts is worse than clean text you can actually use.

What people translate to and from Bengali

Immigration and credential paperwork

Birth certificates, national ID cards, nikahnama/kabin nama marriage contracts, police clearances, and board transcripts (Dhaka, Rajshahi, Chittagong boards; WBBSE and CU in India) all need English versions for UK, US, Canadian, and Australian visa files and for credential evaluators like WES. Upload the document — even a phone photo — and get a faithful English rendering, with Bengali-script names and Bengali-numeral dates carried over accurately. Many authorities require a certified translation for final submission; ours gives you an exact draft to review yourself or hand to a certified translator, instead of paying certification rates just to find out what a document says.

Garment-sector and sourcing business

Bangladesh is the world's second-largest garment exporter, and the paperwork runs in both directions: purchase orders, compliance and factory-audit reports, supplier contracts, and BGMEA or customs correspondence. Translate an English buyer contract into Bengali for a Dhaka or Gazipur supplier, or a Bengali factory notice into English for a compliance team — including XLSX spec sheets and PPTX audit decks, with tables and slide text preserved as clean translated content.

NGO and development field materials

Bangladesh and West Bengal host some of the world's largest NGO operations, and program documents constantly cross the language line: English donor reports, training curricula, and survey instruments going into Bengali for field staff and communities; Bengali field notes, monitoring data, and case studies coming back into English for headquarters. Upload the DOCX or PPTX directly — the translation keeps the document's structure so a field coordinator can work from it the same day.

Family land records and inheritance papers

If you're in the diaspora dealing with property back home, the documents that matter — দলিল (deeds), খতিয়ান/পর্চা (land records), mutation papers, wills — are often decades old, typewritten or hand-lettered, dated in the Bengali calendar (বঙ্গাব্দ), and written in the archaic sadhu bhasha legal register that even fluent relatives struggle with. Photograph each page and upload it; the Advanced tier reads the old register and renders it in plain modern English, so you know exactly what you own and what you're signing before involving a lawyer.

What to watch for in Bengali document translation

The most common failure with Bengali documents happens before translation even starts: text extraction. Legacy Bijoy-encoded PDFs from Bangladesh yield pure mojibake when read as text, and even Unicode PDFs can scramble conjuncts or drop the pre-positioned vowel signs (the ে in কে sits before the consonant it follows), so a translator that trusts the text layer produces confident nonsense — we read suspect pages visually instead. On the language side, the classic errors are register and variant: generic tools translate English into Bengali with the wrong second-person pronoun (তুমি where a notice or letter needs আপনি), miss the Bangladesh/West Bengal vocabulary split, and choke on sadhu bhasha verb forms in older legal text. Going Bengali-to-English, the traps are numbers and names: lakh/crore figures silently misread as thousands/millions, Bengali-calendar dates copied as if they were Gregorian years, and personal names romanized inconsistently (Chowdhury/Choudhury/Chaudhuri, Hossain/Hussain, Md./Mohammad) when immigration paperwork needs the exact spelling on the passport. Our translations flag calendar conversions, keep numerals faithful, and hold one romanization per name across a document — but for certified submissions, always check names against the passport spelling yourself.

Bengali document translation FAQ

Is the English-to-Bengali document translator free?
Yes — upload files up to 4 MB free, which covers most certificates, letters, and short reports. Pro raises the limit to 20 MB for long contracts and scanned multi-page files, and Scholar handles files up to 50 MB and 1,000,000 characters — enough for a full book or a complete land-records bundle.
Can it read scanned documents and phone photos?
Yes. Upload JPG, PNG, or HEIC photos, or PDFs that are really just scans, and we read the Bengali script from the image itself — conjunct ligatures, matra and all. This is also the right path for Bangladeshi PDFs set in legacy Bijoy fonts: their embedded text is scrambled ANSI, so we read the page visually instead of trusting it. A flat, well-lit photo of each page is enough; no separate OCR step.
How accurate is the Bengali translation?
There are two quality tiers. Fast is good for getting the gist of routine documents. Advanced runs a frontier AI model and is what we recommend for anything that matters — legal deeds in sadhu bhasha, certificates where every name and date must be exact, or English business documents where the Bengali needs the right level of formality (আপনি, not তুমি). You can rerun any document on Advanced if the Fast output isn't good enough.
Will the translated PDF look exactly like my original?
No, and that's deliberate. You get the full translated content as clean text and HTML, with headings, paragraphs, and tables preserved, plus a PDF download. We don't attempt a pixel-perfect replica of the original layout — tools that do tend to produce broken conjuncts, overlapping matra lines, and text boxes that don't quite fit, which is worse than a clean document you can actually read, edit, and reuse.
Does it translate into Bangladeshi Bengali or Indian (West Bengal) Bengali?
The output is modern standard (cholito) Bengali, which is fully readable in both Dhaka and Kolkata. The two standards do differ in vocabulary — পানি vs. জল for water, and generally more Perso-Arabic words in Bangladesh versus Sanskritic ones in West Bengal — so for audience-specific material like marketing or community outreach, use the Advanced tier and have a native reader check the handful of words where the variants diverge.
Can it handle old legal documents written in sadhu bhasha?
Yes. Older deeds, statutes, and land records use sadhu bhasha, the archaic literary register with verb forms like করিয়াছে where modern Bengali writes করেছে, and often carry dates in the Bengali calendar and amounts in Bengali numerals. The Advanced tier reads this register and converts dates and figures faithfully. For pre-independence or heavily damaged documents, upload clear photos of each page rather than a compressed scan.
Which file formats can I upload?
PDF, DOCX, PPTX, XLSX, and EPUB, plus JPG, PNG, and HEIC for photographed or scanned pages. Spreadsheets keep their cell structure, slide decks keep their slide order, and EPUB works for full-length books on the Scholar plan.
