- Prepare an entire image library for a consistent upload workflow.

IMAGE GUIDE ✦
Bulk Image Resizing: Resize a Whole Folder Consistently
Bulk resizing applies one sizing rule to many images. It is especially useful for product galleries, blog uploads, property photos, portfolios and any job where dozens of files need the same maximum dimensions.
Each image keeps its own aspect ratio when the lock is enabled, so portrait and landscape files can be processed in the same batch without forcing them into one shape.
How batch resizing works
- Select multiple JPG, PNG or WebP files.
- Choose the target width or height and keep aspect ratio locked unless you have a specific reason not to.
- Process the queue and download the resized batch as a ZIP.
FAQ
Frequently asked questions
Do all images become exactly the same width and height?+
Only if you explicitly supply dimensions that force that result. With aspect ratio locked, the chosen dimension is applied while the other dimension is calculated for each image.
Can I resize 50 or more images?+
The tool is designed for batches, but practical limits depend on device memory and file size. Large mobile photos use much more memory while decoded than their compressed file size suggests.
Why process images as a queue instead of all at once?+
Sequential processing uses much less memory and is more reliable on phones and browsers with strict canvas limits.
Will filenames be kept?+
The processed files keep recognizable source names so the downloaded batch is easy to match to the originals.
Should I compress after resizing?+
If you also need the smallest practical files, resizing first and then compressing can make sense. The two tools solve different parts of the problem.
