Scale a photo or graphic relative to its current dimensions instead of calculating a new width and height. The browser preserves the source aspect ratio, shows the resulting pixel dimensions, and creates the resized copy without sending the image anywhere.
How to use Percentage Resizer
- Choose a JPEG, PNG, or WebP image.
- Enter a percentage from 1% to 500% and choose the output format.
- Process the image, confirm its new dimensions, and download the scaled copy.
Things worth knowing
- 50% halves both width and height, producing one quarter of the original pixel count.
- Enlarging above 100% cannot restore detail that is not present in the source.
- The 20 megapixel and 12,000-pixel output limits still apply.
Frequently asked questions
Does percentage resizing stretch the image?
No. Both dimensions use the same scale, so the original aspect ratio is preserved.
Why is a dimension rounded by one pixel?
Pixel dimensions must be whole numbers. The browser rounds each scaled dimension to the nearest pixel.
