FAQ

Frequently asked questions

Yes. Enable the aspect ratio lock (the chain icon). When locked, entering a width automatically calculates the correct height, and vice versa. This prevents image distortion.

The output format matches the input format. JPG in → JPG out, PNG in → PNG out. PNG transparency is preserved. If you want to convert formats, use our dedicated PNG to JPG or WebP to JPG tools.

With aspect ratio locked, you only need to enter one dimension. Leave the other field empty and the tool will calculate it proportionally based on the original image dimensions.

No. All resizing is done in your browser using the Canvas API. Your images never leave your device.

Yes. You can set dimensions larger than the original. However, standard canvas scaling will interpolate pixels and the result may look blurry. For better upscaling quality, use our AI Upscale Image tool.

Yes. Set your dimensions once and add multiple images. All selected images will be resized to those dimensions when you click Resize Images. Download all as a ZIP.
