Frequently Asked Questions

Can I resize an image without distorting it?

Yes. Enable the 'Lock Aspect Ratio' option and the tool will automatically calculate the correct height when you enter a width, keeping proportions intact.

What formats are supported?

JPG, PNG, and WebP are all supported for both input and output.

Does resizing reduce file size?

Yes. Reducing the pixel dimensions of an image directly reduces its file size, since there are fewer pixels to store.

Can I upscale a small image to a larger size?

Yes, but upscaling beyond 2× the original dimensions will reduce sharpness because the tool must interpolate new pixels.

Will the resized image have a watermark?

No. The tool is completely free and adds no watermarks to your images.
