NanoImage HomeCompress multiple images in one go.
Batch image compression means reducing the file size of multiple images at the same time instead of compressing them one by one. It helps you optimize image folders faster, especially when preparing website assets, blog images, product photos, or social media graphics.

You should use batch compression whenever you need to optimize multiple images at once. Common use cases include compressing product photos, blog images, website banners, portfolio images, screenshots, thumbnails, and marketing assets before publishing them online.
NanoImage supports common web image formats including JPG, PNG, WebP, and other widely used image types. The best format depends on your use case: JPG is common for photos, PNG is useful for transparency and screenshots, and WebP is a strong choice for modern web performance.
