About the image resizer
How this tool works
Image resizing is one of the most common browser-side tasks because file slots, article layouts, and CMS rules rarely use the same dimensions. This tool keeps that workflow fast and local.
Instead of opening a heavy editor for a one-off resize, you can upload the image, adjust the target size, and download the result immediately.
Where it is useful
The result panel shows the output width, height, and size so you can confirm the resized image before saving it.
The same registry-based widget also supports later image operations, which keeps the category scalable without custom page logic.
- Prepare images for CMS, blog, or marketplace upload limits.
- Resize screenshots or graphics for docs and presentations.
