About the Image Resizer
Set an exact width and height for a JPEG, PNG or WebP image. Keep the aspect ratio locked to avoid distortion, choose the output format and download a new copy while the original remains untouched.
Width, height and aspect ratio
Aspect ratio describes the shape of an image. With the lock enabled, changing the width recalculates the height from the original ratio and vice versa. Turn it off only when you deliberately need exact independent dimensions.
FAQ
Does resizing upload my image?
No. Reading, resizing and exporting happen locally in your browser. Your image never leaves your device.
What does keep aspect ratio mean?
It keeps the original relationship between width and height. Changing one dimension automatically updates the other, preventing the image from looking stretched.
Can I make a small image larger?
Yes, but enlarging cannot create detail that was not present in the source. A much larger result may look soft or pixelated.
