About this tool: Image Resizer
Resize JPG, PNG and WebP images locally by pixel dimensions or percentage, with optional aspect-ratio locking.
The workflow is designed for common browser-supported image files, with a preview so you can inspect the result before downloading it.
Image Resizer is presented in the shared NexterHub tool layout so the working controls stay near the top while the method, example, limitations and related utilities remain available below the result.
How it works
Image Resizer processes the selected image in the browser. Heavy OCR, HEIC or segmentation code is loaded only for the tools that need it, keeping normal pages lighter.
Practical example
A 2400×1600 image resized to 1200 px wide with aspect ratio locked becomes 1200×800.
Important notes
Check the preview, output dimensions, format and file size before replacing an original image.
