What Is a Bulk Image Resizer?
A bulk image resizer is a tool that lets you resize multiple images in a single action, instead of uploading and adjusting each file one by one. Rather than repeating the same resize steps dozens of times, you set your target dimensions once and apply them across your entire batch.
This is often called batch image resizing — a workflow built specifically for people handling large volumes of images, like product photos, blog graphics, or social media content.
