Will resizing an image to be larger make it blurry?

Yes, enlarging an image beyond its original resolution stretches existing pixels and typically introduces some blurriness, since no new detail can be created. Resizing down to a smaller size doesn't have this problem.

Does resizing change the image format?

No, the resizer keeps your original file format (JPG stays JPG, PNG stays PNG) — only the pixel dimensions change, unless you separately choose to convert the format using one of our converter tools.

What's the difference between resizing and cropping?

Resizing changes the overall dimensions of the whole image while keeping all of its content, whereas cropping removes part of the image to keep only a selected region. Use our Image Cropper if you need to cut out a specific area instead.

Can I lock the aspect ratio while resizing?

Yes, keeping the aspect ratio locked prevents the image from looking stretched or squashed; unlocking it lets you set width and height independently if that's what you need.
