Melhores ferramentas para compressão de imagens no navegador
In today’s digital world, fast-loading images are essential. Whether you run a website, upload photos to social media, or simply need to send pictures by email, using images with large file sizes can slow down loading speeds, affect user experience, and even hurt your SEO rankings. That’s why image compression has become an everyday necessity—not just for photographers and designers, but for anyone who deals with digital content.
Browser-based image compression tools make this process incredibly convenient. You don’t need to install software, configure complicated settings, or worry about device compatibility. With just a few clicks, you can reduce an image from several megabytes to a few hundred kilobytes—all directly in your web browser.
