Start Your Free Accurate Translation“This is the most reliable free Portuguese to Spanish translation I've seen. It handles Brazilian and European Portuguese legal jargon, such as 'propriedade intelectual' and 'certidão negativa', bringing it accurately into Spanish with Chilean, Mexican, or Spain-specific terminology—something generic translators often fail to capture.”Dr. Camila Soria, Traductora Pública, Colegio de Traductores Públicos de la Ciudad de Buenos Aires

Guarantee Perfect Accuracy with a Free Custom Dictionary
Absolute accuracy means preserving your company’s technical language. Our Custom Dictionary lets you lock your preferred Spanish translations so your documents never lose meaning, tone, or legal compliance. A free feature for zero errors.

Make sure terms like 'Petrobras' always stay as your registered brand, not generic 'compañía petrolera'.
Technical Correctness

Regional Nuance
Differentiate between 'ônibus' as 'autobús' in Spain or 'camión' in Mexico based on your audience.
Legal Equivalence
Specify phrases like 'declaração de imposto de renda' as 'declaración de la renta' in Spain or 'declaración de impuestos' in Latin America.

Legal & Corporate
Scenario:
Translating a Brazilian 'contrato social' for registration with the Chilean Department of Companies.
Challenge:
Mistranslating 'CNPJ' (Brazilian company registry) as something like 'NIF' could result in rejected filings, as Latin American registrars expect terminology such as 'RUT' (Chile) or 'CUIT' (Argentina).
Solution:
Our AI correctly localizes company registry terms, legal clause structure, and ensures compliance with local regulations like the Ley de Sociedades in Spain or the Ley de Sociedades Comerciales in Argentina.
Finance & Trade
Scenario:
Converting Brazilian or Portuguese annual reports for investors in Mexico, Spain, or Colombia.
Challenge:
Generic tools misinterpret monetary formatting (e.g., 'R$ 1.500,50' vs. '€1.500,50') or tax terms. They might mistranslate 'lucro líquido' as 'lucro neto' instead of 'utilidad neta' for Latin America.
Solution:
Our AI adapts financial terms and formats to each target jurisdiction, guaranteeing clarity for assets, losses, and operational vocabulary as required by the Spanish-speaking financial sector.
Technical & Engineering
Scenario:
Localizing a Brazilian instruction manual for Madrid or translating a safety data sheet from Portugal for a factory in Mexico.
Challenge:
'Chave de fenda' rendered as 'llave de fenda' instead of correct 'destornillador' could cause safety incidents. 'Quadro de distribuição' must be 'cuadro eléctrico', not a literal 'cuadro de distribución'.
Solution:
With Spanish technical databases, our AI yields accurate components, parts, and safety warnings adapted to Spain, Mexico, Colombia, and Argentina—with the option to lock your preferred glossary.
