What this tool does
It produces an image with exactly the width and height you enter, in pixels. With Keep aspect ratio on, changing one side updates the other so nothing is distorted. Turn it off when you need a specific shape, then choose what happens to the difference:
- Crop to fill: the image is scaled to cover the whole area and the overflow is trimmed from the edges, keeping the centre.
- Fit inside: the whole image is kept and borders (a colour of your choice, or transparent) fill the gaps.
- Stretch: the image is squeezed to the new shape, which distorts it.
The result is decoded again after saving, and the label confirms the real dimensions of the file you download.
When it's useful
- Websites and online shops that require a fixed size, such as 1000 × 1000 px product images.
- Presentation slides and video backgrounds at 1920 × 1080.
- Profile pictures and avatars that must be square.
- Halving a photo (50%) before emailing it.
How to use it
- Choose an image. Its original size fills the width and height fields.
- Type the new width (and height if the ratio is unlocked), or switch to percent.
- Pick the output format. "Same as original" keeps JPG as JPG and PNG as PNG.
- Press Resize image and download the result.

Need many images at once? Use Batch resize. Need platform sizes like a YouTube thumbnail? Use Social media sizes.
Limitations
- Enlarging an image adds pixels but not detail, so big enlargements look soft.
- The largest output is 16,384 px per side, and about 16.7 megapixels on iPhone and Safari (50 MP in other browsers).
- JPG output has no transparency. Transparent areas are filled with white, or with your border colour when you use Fit inside.
- Metadata is removed. Photos are turned upright from their orientation tag before resizing.
