Yes. PDFTash uses Tesseract with the Bengali (ben) language pack, which is specifically trained on Bengali script. This includes full recognition of all 11 vowels (স্বরবর্ণ), 39 consonants (ব্যঞ্জনবর্ণ), all vowel marks (মাত্রা like ি, ী, ু, ূ, ে, ৈ, ো, ৌ), and common consonant conjuncts (যুক্তাক্ষর like ক্ষ, জ্ঞ, স্ত, ন্ত). For clean 300 DPI scans of printed Bengali text, expect 90-95% accuracy. Always select Bengali as the language when uploading — the language selection activates the correct trained model.
Scan at 300 DPI minimum for Bengali documents. Bengali script has complex vowel marks (মাত্রা) that sit above, below, before, and after consonants. At 150 DPI, these small diacritical marks lose detail and become indistinguishable, causing the OCR engine to miss or misidentify them. For older books, degraded documents, or very small font sizes, use 400–600 DPI. The resulting large file can be compressed afterwards with PDFTash Compress Scanned PDF to reduce storage size.
Yes, easily. After running OCR on your Bengali PDF and downloading the text or searchable PDF, go to the PDFTash Translate PDF tool. Upload the result and select English as the target language. PDFTash will translate the Bengali text to English. Alternatively, you can upload your original scanned Bengali PDF directly to Translate PDF — it automatically runs OCR first and then translates, saving you one step. The translation supports Bengali to English, Hindi, Arabic, French, Spanish, German, Chinese, Japanese, and more.
Yes, with some caveats. Modern laser-printed or offset-printed Bengali books (post-2000) work very well and achieve 90-95% accuracy at 300 DPI. Books from the 1980s–1990s with older metal-type or early digital typefaces may have 75-85% accuracy. Older publications from the 1950s–1970s with handset metal type or distinctive historical typefaces can be more challenging. For old books, scan at 400–600 DPI and ensure the scan is flat and well-lit. Yellowed or foxed pages benefit from scanning in grayscale rather than color.
