What it does
This tool changes the pixel dimensions of an image. Set a target size and the image is scaled to it in your browser — nothing is uploaded. On pages with a fixed width and height, the picture is scaled to fill that frame and the overflow is trimmed from the centre, so it is never stretched. On pages with only a width, the height follows the original proportions.

Frequently asked questions
Is my image uploaded anywhere?
No. The resize happens in your browser, and the file never leaves your device.
Will my image be stretched or distorted?
No. The image keeps its proportions. When both width and height are fixed, it is scaled to fill the frame and the overflow is cropped from the centre.
Which format is the result?
JPG and WebP images keep their format. Other formats are saved as PNG so transparency is preserved.
Is there a file size limit?
Files up to 30 MB are accepted. Very large images can run out of memory on older phones; if that happens, try a smaller file.
