About image resizing
Change image dimensions by entering a width, height, or percentage. The other dimension is calculated for each image so its original aspect ratio is preserved.
How to use
- Add one or more JPG, PNG, or WebP images.
- Choose Width, Height, or Scale and enter a value.
- Download each resized image or all results in a ZIP file.
The same setting is applied to every selected image while preserving each image's own proportions.
Resize methods
Width
Set the output width in pixels. Height is calculated automatically.
Height
Set the output height in pixels. Width is calculated automatically.
Scale
Resize relative to the original dimensions. Use a preset or enter any value from 1% to 500%.
Aspect ratio
This tool always preserves aspect ratio and never stretches images. Width and height cannot be changed independently, and images are not cropped.
Your images are not uploaded
Images are decoded, resized, and encoded in your browser. nicolet.jp does not receive or store your image files.
