The 640×360 Image Converter is a straightforward online tool that lets you quickly resize any picture to a width of 640 pixels and a height of 360 pixels. This is a common resolution for web videos, banners, thumbnails, and digital displays. You do not need to download any software or learn complicated editing programs. Just upload your image, choose your preferred format, click the button, and your resized image will be ready to download within seconds.

How It Works
The converter uses an HTML5 canvas that runs entirely in your browser. That means your images never get uploaded to a server, they stay on your device the whole time. Once you select a file from your computer, it appears on the preview canvas. You can then adjust the width and height (default is 640×360), pick the output format you want, and click Resize Image. The tool instantly creates the new version for you to save.

Tips for Best Results
Start with a larger, high-quality image to prevent blurriness after resizing.
Use PNG or WEBP for graphics that need a transparent background.
Keep the aspect ratio in mind to avoid stretched images.
For sharper results, avoid repeatedly resizing the same image, work from the original each time.
