Zip vs Zipx vs Rar vs 7z, Explicado

Ultima revisao: 2026-04-27. Abra a ferramenta zip para criar o arquivo de compatibilidade universal no seu navegador.

Resposta de 30 segundos. Quatro formatos, quatro eras de compressao. Zip (1989, Deflate) abre em todo lugar sem instalacao. Zipx (2008, container do WinZip para algoritmos mais novos) abre apenas com WinZip ou ferramentas compativeis. Rar (1993, proprietario) e mais recebido, raramente criado. 7z (1999, LZMA2) comprime menor mas precisa de download. Para enviar: use zip a menos que ambos os lados tenham algo melhor instalado.

Os quatro formatos lado a lado

Formato	Algoritmo padrao	Abre nativamente em	Compressao tipica vs zip
Zip	Deflate	Windows, macOS, iOS, Android	linha de base (1.0x)
Zipx	LZMA, PPMd, BZip2	Apenas compativeis com WinZip	0.7-0.9x
Rar	Algoritmo proprio do Rar	Nenhum - extrator necessario	0.8-0.9x
7z	LZMA2	Nenhum - 7-Zip / Unarchiver necessarios	0.7-0.85x

Para que serve cada um

Zip. O padrao universal. Embutido em todo sistema operacional e celular desde 2010. Use para qualquer coisa enviada a um destinatario nao-tecnico.

7z. Open-source, moderno, o menor. A escolha certa para armazenamento de arquivamento de longo prazo e para qualquer transferencia grande onde ambos os lados tem 7-Zip ou The Unarchiver instalados.

No tracking during tool use. Analytics ends at the page view. The actual input you paste, drop, or capture is never sent to any server and never written to any log.
Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
