Portuguese Document Translator — English ↔ Portuguese

How Portuguese documents come out

Portuguese uses the Latin alphabet, written left to right, so there is no direction flipping to worry about — the real document issues are subtler. Portuguese leans heavily on diacritics (á, â, ã, à, ç, é, ê, í, ó, ô, õ, ú), and losing one changes the word: avó is grandmother, avô is grandfather; é means "is" while e means "and". Spelling also depends on the document's age: the 1990 Orthographic Agreement (fully in force in Portugal since 2015 and Brazil since 2016) dropped silent consonants (acção → ação, óptimo → ótimo) and Brazil's trema (lingüiça → linguiça), so older certificates and contracts carry spellings a naive system flags as errors. Expect translated text to grow: Portuguese typically runs 15–30% longer than English, which is exactly why squeezing it back into the original page geometry breaks tables and slides. Numbers use a decimal comma (1.234,56), dates run day/month/year, months and weekdays are lowercase, and Portuguese publishers traditionally set quotations in «guillemets» where Brazilian ones use curly quotes. Formal European Portuguese also hyphenates pronouns onto verbs (traduzi-lo, dir-lhe-ei), which trips up OCR line-break handling in scanned documents.

What to watch for in Portuguese document translation

The failure modes in Portuguese document translation are specific. OCR that drops diacritics silently rewrites the text — é becomes e ("is" becomes "and"), avó becomes avô, and cedilla loss turns real words into different real words, so errors slip past spellcheck. Older documents use pre-1990 spellings (acção, óptimo, lingüiça) that confuse systems trained only on reformed orthography. False friends are dense in exactly the documents people upload: pretender means to intend, assistir means to attend or watch, parentes are relatives not parents, and eventualmente means "possibly" in Portugal — not "eventually". Numbers written with decimal commas (1.234,56) get corrupted when a translator or spreadsheet reinterprets them with English punctuation. Legacy PDFs encoded in Latin-1 arrive as mojibake (ã rendered as ã) and need repair before translation. And documents that mix Brazilian and European conventions — common in companies operating in both markets — read as sloppy unless the translation commits to one variant, which is where the Advanced tier's document-level consistency matters.

Portuguese document translation FAQ

Is it free to translate a PDF from English to Portuguese?

Yes, for files up to 4MB — enough for most contracts, certificates, letters, and papers. Pro raises the limit to 20MB, and Scholar handles files up to 50MB and 1,000,000 characters, which covers full books and dissertations. Every tier supports every format.

Can it translate a scanned document or a photo of a page?

Yes. Upload scanned PDFs or photos in JPG, PNG, or HEIC and the text is OCR'd before translation. Check diacritics on low-quality scans — a dropped tilde or cedilla changes the word (maçã is apple, maça is a mace). Printed and typed documents work well; heavy cursive handwriting is variable, and the Advanced tier reads difficult scans better.

Do I get Brazilian or European Portuguese?

Spelling follows the 1990 Orthographic Agreement, which Brazil and Portugal now share, so the written output is valid in both. Word choice leans Brazilian by default, since pt-BR dominates written Portuguese. Translating from Portuguese, both variants are handled — the system reads ficheiro and arquivo, ecrã and tela, utilizador and usuário equally. The Advanced tier is better at keeping variant-specific vocabulary and formal register consistent across a long document.

Will my document's formatting be preserved?

You get clean translated text with your paragraphs, headings, lists, and tables intact, viewable as a web page and downloadable as a PDF — not a pixel-for-pixel replica of the original layout. That is deliberate: Portuguese runs 15–30% longer than English, and forcing it back into the original page geometry produces shrunken, broken text. Clean output is readable, searchable, and easy to copy into your own template.

How accurate is the translation?

Two quality tiers. Fast is good for getting the gist of routine documents and for bulk work. Advanced, powered by a frontier model, is what you want for contracts, academic writing, and anything official-adjacent: it keeps legal register, resolves false friends (pretender means to intend, compromisso is an appointment or commitment), and stays consistent with pt-BR or pt-PT conventions across the whole file.

Can I use this for official purposes, like a tradução juramentada?

No — and no machine translation can be. Brazil requires official documents to be translated by a sworn tradutor juramentado, and US, UK, and Portuguese authorities require certified human translations for legal filings. Use this tool for what comes before and after: understanding a document fully, preparing an accurate draft, or checking a translation you paid for — sworn translation is billed per page, so knowing exactly which pages you need saves real money.

What file types can I upload?

PDF, DOCX (Word), PPTX (PowerPoint), XLSX (Excel), EPUB, and photographed or scanned documents as JPG, PNG, or HEIC. Size limits are 4MB free, 20MB on Pro, and 50MB on Scholar, with Scholar also extending the per-document limit to 1,000,000 characters.
