Why Use a Bulk Image Compressor?
When you need to bulk compress images, opening each file separately rarely scales. Product photography, blog posts, and marketing campaigns often mean dozens or hundreds of files — and many people want to compress images in bulk so quality and dimensions stay consistent across the set. If you mass compress images after a shoot or compress batch images from one folder export, one workflow trims total storage and avoids repeating the same save dialog in a desktop editor.
