FAQ

Yes, completely. All processing is done client-side in your browser. No data or images are ever sent to any server. Your files never leave your device.

The tool supports common formats including JPEG, PNG, WebP, and GIF. You can download the result in your preferred format.

When the aspect ratio lock is enabled, changing the width automatically recalculates the height proportionally, and vice versa. This prevents your image from appearing stretched or distorted.

No installation is required. The tool runs entirely in your web browser, so you can use it on any device without downloading anything.

Yes, the image resizer is completely free with no usage limits or hidden fees.
