Resize a JPG while preserving its proportions
Change the pixel dimensions of a JPG without stretching it. Enter a width, a height, or both.
When both values are supplied, NetroDoc fits the image inside that bounding box while preserving the original aspect ratio.
How to resize a JPG
Upload the JPG
Choose one valid JPG image.
Set the dimensions
Enter a maximum width, height, or both.
Download the resized JPG
Save the proportional JPG produced by NetroDoc.
How proportional resizing works
One dimension is calculated automatically when only width or height is supplied. When both are supplied, the image is fitted inside the requested box without cropping or stretching.
The resized JPG is re-encoded at quality 90 with optimization enabled. Metadata may not be retained.

Privacy →Resize JPG FAQ
Will the image be stretched?
No. The original aspect ratio is preserved.
What happens when I enter width and height?
The image is fitted inside that bounding box, so one side may be smaller than the entered maximum.
Does resizing crop the image?
No. This tool resizes the full image without cropping.
