When every image in a set needs to be the same size, doing them one at a time is a waste of an afternoon. Batch resizing applies one rule to the whole folder.
Who needs batch resizing
Online shops standardizing product photos, teams preparing assets for a website, and anyone uploading galleries all benefit. Consistent dimensions make layouts look tidy and pages load predictably.
How to resize images in bulk
- Open the Bulk Image Resizer.
- Drop in all your images at once.
- Set a target width or height, or a maximum dimension to fit within.
- Download the resized set as a zip.
Choosing a strategy
- Fixed width: good for content images that sit in a single-column layout.
- Fit within a box: useful when images are a mix of portrait and landscape and you want none of them to exceed a limit.
- Keep the aspect ratio locked so nothing stretches.
Resize then compress
After resizing, run the batch through the Bulk Image Compressor to cut file sizes too. Both tools work in the browser, so even large client sets stay private.
Frequently asked questions
Can I resize images of different shapes together?
Yes. Lock the aspect ratio and set a maximum dimension so portrait and landscape images all fit within the same bounds without distortion.
Will batch resizing distort my images?
Not if you keep the aspect ratio locked. The tool scales each image proportionally.
How do I download all the resized images?
They are bundled into a single zip file for one-click download.
