What is Bulk image compressor?

A bulk image compressor that reduces file sizes for multiple images at once. Upload several images and the tool compresses them whilst attempting to maintain acceptable quality. This is useful if you need to prepare batches of images for websites, emails, or storage where file size matters. The service runs in your browser, so there's no software to install. It's free to use with no account required, making it straightforward for occasional users who need quick compression without subscription costs.
