Zip Online vs 7z vs Rar - Qual Escolher

Ultima revisao: 2026-04-27. Abra a ferramenta zip para criar arquivos no navegador sem upload.

Resposta de 30 segundos. Zip quando o destinatario esta no Windows, macOS ou qualquer telefone - e o unico formato que abre sem software extra. 7z quando voce controla as ferramentas do destinatario e quer o menor arquivo. Rar quando voce deve abrir um.

O que cada formato e

  • Zip. Formato de Phil Katz de 1989. Nativo no Windows desde XP, nativo no macOS, nativo em Android e iOS. Compatibilidade universal, compressao modesta.
  • 7z. Formato de Igor Pavlov de 1999. Usa LZMA2 por padrao - tipicamente 10-30% menor que zip em arquivos com muito texto. Precisa de 7-Zip, The Unarchiver ou app paga para abrir.
  • Rar. Formato proprietario de 1993. Gratis para extrair, pago para criar com WinRAR oficial. Compressao forte similar ao 7z.

Para envio: use zip a menos que ambos os lados tenham algo melhor instalado. Veja zip vs zipx vs rar vs 7z, explicado para a comparacao mais profunda.

Why trust these tools

  • Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
  • Truly in-browser - no upload. Every file-processing tool on this site runs in your browser through modern Web APIs (File, FileReader, Canvas, Web Audio, WebGL, Web Workers). Your photo, PDF, audio, or text never leaves your device.
  • 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.
