How to Resize Multiple Images at Once (Bulk Resize)
Product shots, slide images, upload files… editing dozens one at a time is painful. Batch them to the same size and it takes seconds.
You often need several photos at the same width — store product images, blog or slide assets, application files. Instead of opening an editor for each one, batch them and it’s far faster.
Resize them all in one batch
The image resizer processes many files at once. Set one width and every photo you drop in is resized to it, keeping each one’s ratio.
- Drag in every photo, or click to select
- Choose ‘Width (px)’ and enter the value (say 1000)
- Press ‘Resize’ to process them all, then download each
Photos with different ratios are all matched to the same width, so their widths line up. If you need a specific ratio like square, crop to it in a photo app first, then resize.
Scale them all by percent
To shrink mixed-resolution photos by a ratio — say ‘all to 50%’ — use percent mode. Each is scaled by the same proportion of its original.
Compress after matching size
To also lighten the files, drop the resized set into the image compressor and batch-compress. For web and upload optimization, see the guide on optimizing images for the web.
If iPhone HEIC photos are mixed in
HEIC files may not be recognized. Convert them to JPG first with the HEIC to JPG converter, then bulk resize.
Frequently asked questions
- How many at once? It depends on your browser and device, but dozens usually process without trouble.
- Photos with different ratios? Each keeps its ratio while the width is unified; heights vary per the original.
- Is it safe? Everything runs in your browser; files are never sent to a server.
