🇮🇷Persian — 3,000 Years of Continuous Literary Tradition, Spoken Across Three Nations

I was working with an engineering consultant who had won a contract with an Iranian petrochemical company before the current sanctions environment tightened up. Everything — technical specifications, procurement documents, quality control procedures — came back from the Iranian side in Persian. He had one Iranian-born engineer on his team who was reading everything, but she was a mechanical engineer, not a translator, and the administrative and legal sections were slowing her down significantly. I showed her this tool during a team meeting. She uploaded a 28-page procurement spec, ran it through in two minutes, and said "that's actually pretty good for the technical parts." Coming from a native Persian speaker reviewing a machine translation of a Persian engineering document, I'll take that.

Persian (known as Farsi in Iran, Dari in Afghanistan, and Tajik in Tajikistan) is spoken by around 110 million people across three countries and a large global diaspora. It's one of the oldest continuously-used literary languages in the world — Persian poetry and literature from over a thousand years ago is still readable to modern speakers. The language uses a modified Arabic script written right-to-left, with four additional letters not found in Arabic (پ، چ، ژ، گ). This RTL direction is handled correctly in the preview panel, which uses Noto Nastaliq Urdu — the closest freely available web font to traditional Persian Nastaliq calligraphy style.

🖋️The Persian Script — Nastaliq Style, RTL, 4 Unique Letters

Persian uses a 32-letter alphabet based on Arabic script, plus four letters unique to Persian. All are rendered correctly in the preview using Noto Nastaliq Urdu font:

Persian Nastaliq is a calligraphic script style where letters connect fluidly and flow diagonally downward from right to left — quite different from the block Naskh style used in standard Arabic. The preview uses Noto Nastaliq Urdu which closely approximates this flowing style, giving the text a natural and readable appearance to Persian readers.

🌍Persian, Dari and Tajik — One Language, Three Names, Three Countries

The Google Translate API uses `fa` as the language code, which targets Modern Standard Persian (Farsi) as spoken and written in Iran. This is mutually intelligible with Dari and readable to most Tajik speakers familiar with the Arabic-script writing system.

📋How to Translate PDF to Persian — 4 Steps

👥Who Uses PDF to Persian Translation?

• Energy and petrochemical sector: Iran holds the world's second-largest natural gas reserves and fourth-largest proven oil reserves. Companies working with Iranian energy partners — directly or through intermediaries in Turkey, UAE, and Iraq — deal with Persian-language technical specifications, safety documentation, and procurement contracts constantly.
• Iranian diaspora and immigration professionals: Millions of Iranian nationals living in the US, Germany, Canada, Sweden, and the UK need documents translated between Persian and their host country language — university diplomas, birth certificates, marriage records, professional licences, legal filings.
• Companies operating in Afghanistan: NGOs, development agencies, international contractors, and humanitarian organisations working in Afghanistan deal with Dari-Persian documents for procurement, project reporting, legal filings, and community communication.
• Academic and research community: Persian literature, poetry, philosophy, and history is a rich academic field. Iran also produces substantial scientific research output in engineering, medicine, and materials science. Researchers need working translations of Persian academic papers.
• Trade professionals: Iran is a significant trading partner for Turkey, UAE, China, India, and several Central Asian countries. Despite sanctions, significant trade flows through legal channels, generating Persian-language trade documentation, certificates of origin, and customs paperwork.
• Translation and localization industry: Professional translators use this tool to generate working drafts quickly before applying their expertise to refine and certify the final output.

🔬PDF to Persian — Tool Comparison

Here's the thing with Persian machine translation: DeepL doesn't support Persian at all as of early 2026, which makes Google Translate the only realistic free option for this language pair. And honestly, Google Translate's Persian is genuinely solid — Iran has a very active internet presence and Google has enormous Persian-language training data from news sites, Wikipedia, social media, and academic papers. Technical and business content translates clearly. Idiomatic or literary Persian, predictably, is where it gets shaky. But for working documents — specs, reports, contracts, forms — the output is accurate and readable.

💡Tips for Better Persian Translation Quality

• RTL is correct in the preview panel: The translation preview uses dir="rtl" and Noto Nastaliq Urdu font. Text flows from right to left naturally. If you copy the preview text into another application, make sure that app also has RTL support enabled for it to display correctly.
• Persian and Arabic share a script but are different languages: Persian uses 28 Arabic letters plus 4 unique ones (پ چ ژ گ). Don't select Arabic as the target — this tool is for Persian. If you need Arabic, use our PDF to Arabic tool.
• Persian is a Subject-Object-Verb language: Like Turkish and Japanese, Persian puts the verb at the end. "I the bread ate" is correct Persian structure, not a translation error. Machine translation handles this well for standard content.
• Ezafe construction is a key Persian feature: Persian links nouns and adjectives with a vowel sound (ezafe) written as a short vowel mark — often omitted in modern informal text. Machine translation handles this correctly for most content.
• Scanned PDFs need OCR first: Run OCR PDF first if your PDF is a scanned image, then translate to Persian.
• For certified translation use a professional: Iranian courts, consular services, and official bodies require certified translation by an accredited translator. This tool is for working documents and understanding content.
