Folheto vs. panfleto vs. brochura
While folheto, panfleto, and brochura are often used interchangeably to translate brochure, flyer, or leaflet, they effectively describe different physical formats and levels of complexity. The key differences lie in whether the paper is folded, bound, or loose, as well as the context in which they are distributed.
Folheto
A2A folheto generally refers to a single sheet of paper that has been folded one or more times (like a tri-fold) to organize information. It is standard for informational handouts, tourism guides, or supermarket deals.
O médico entregou-me um folheto explicativo sobre os efeitos secundários do medicamento.
(The doctor handed me an explanatory leaflet about the medicine's side effects.)
Deixaram um folheto do supermercado na minha caixa de correio com as promoções da semana.
(They left a supermarket leaflet in my mailbox with the week's promotions.)
Este folheto turístico tem um mapa excelente do centro histórico.
(This tourist brochure has an excellent map of the historic center.)
Panfleto
B1A panfleto is typically a single, unfolded sheet of paper usually printed on lower quality paper for mass distribution. While often used for cheap advertising (flyers), historically it carries a strong connotation of political or aggressive ideological messaging.
Os manifestantes distribuíram um panfleto a exigir melhores condições de trabalho.
(The protesters distributed a pamphlet demanding better working conditions.)
Alguém me deu um panfleto na rua a anunciar a abertura de um novo ginásio.
(Someone gave me a flyer on the street announcing the opening of a new gym.)
A campanha eleitoral encheu as ruas de panfletos com a cara do candidato.
(The electoral campaign filled the streets with flyers featuring the candidate's face.)
Brochura
B2A brochura is the most substantial of the three, referring to a booklet consisting of multiple pages that are bound, stitched, or stapled together. It implies higher production value and is used for corporate catalogs, premium product showcases, or detailed manuals.
A agência imobiliária preparou uma brochura luxuosa com fotos dos apartamentos.
(The real estate agency prepared a luxurious brochure with photos of the apartments.)

Summary
To choose the right word, consider the format and purpose: use panfleto for a simple loose flyer or political text; use folheto for a folded sheet used for information or promos; and use brochura for a multi-page bound booklet or catalog.
