How to resize an image
Choose an image using the resizer above and adjust the available width, height or size settings. Download the result and inspect its dimensions before using it. If the tool provides an aspect-ratio lock, keep it enabled when you want to avoid stretching or squashing the image.
Understand pixels, dimensions and file size
Image dimensions describe width and height in pixels, while KB or MB measures the storage size of the file. Reducing dimensions can lower file size, but the final result also depends on image format and compression. A smaller image may look sharp on a phone yet appear blurry when enlarged for a poster or print.
Choose sizes for different uses
A website thumbnail, profile picture, document scan and printed photograph can have very different requirements. Check the destination’s recommended dimensions, aspect ratio and accepted formats before exporting. Preserve the original image so you can create separate versions for each purpose without repeatedly resaving a reduced copy.
Frequently asked questions
Does resizing improve a blurry photo? No; it does not restore missing detail. Why does the image look stretched? Width and height may have been changed without preserving the original ratio. Is resizing the same as cropping? No; cropping removes part of the picture, while resizing changes its dimensions.
