Sobre imageresize.co

imageresize.co é uma ferramenta gratuita de processamento de imagens que permite redimensionar, comprimir e converter imagens diretamente no navegador — sem uploads, sem registro, sem limites.

Todo o processamento acontece localmente no seu dispositivo via Canvas API, ou seja, suas imagens nunca saem do seu computador. Levamos a sério a sua privacidade.

Suportamos JPEG, PNG, WebP, TIFF, HEIC e AVIF. Você pode redimensionar, comprimir para um tamanho em KB ou converter entre formatos.

ImageResize.co supports 25 languages and is accessible worldwide. The interface adapts to right-to-left scripts for Arabic and Persian users, and uses language-specific fonts for scripts such as Devanagari, Chinese, Japanese, Korean, Bengali, and Thai.

We believe powerful image tools should be accessible to everyone, everywhere, for free. That is why ImageResize.co requires no account, no credit card, and no software download. Open the site, select your images, and get results in seconds.
