Como Comprimir um Zip para um Tamanho Menor
Ultima revisao: 2026-04-27. Abra a ferramenta zip para re-comprimir no navegador sem upload do arquivo.
Por que re-zipar nao faz quase nada
Zip usa o algoritmo Deflate. Deflate encontra padroes de bytes repetidos e os substitui por codigos mais curtos. Apos uma passagem, os padroes desaparecem. Uma segunda passagem nos mesmos dados nao encontra nada para substituir.
O que funciona: extrair, comprimir, re-zipar
- Extraia o arquivo localmente para que voce possa ver os arquivos individuais.
- Execute o compressor certo nos pesados. Um JPEG de 5 MB cai para menos de 1 MB via compressao de imagem.
- Re-zipe os arquivos menores. Use compressao Best em documentos e Store na midia (agora menor).

- No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
- Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
- 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.
