How to Batch Resize Images
Resizing dozens of images one by one is tedious. Batch resize uploads all of them, applies the same dimensions, and packages everything into a single ZIP download — with original filenames preserved.
Batch Resize Images Online Free
Batch resizing lets you resize many images to the same dimensions at once, instead of doing them one by one. ImageZen4u resizes entire batches in your browser, downloading them all as a single ZIP archive.
Common uses and tips
Batch resizing saves enormous time when you have dozens or hundreds of images that all need the same dimensions — product photos for an online shop, images for a photo gallery, thumbnails for a blog, or photos to email. Instead of resizing each one manually, you process the whole set in one operation. The tool preserves aspect ratios and lets you choose the output format and add a filename prefix for easy organisation.
