Image Resizer
How It Works
This converter uses an HTML5 canvas built directly into the page. All resizing happens inside your own browser, so your images are never uploaded to a server. That means your files remain private and the process is fast. Once you upload a file, it appears on the screen so you can preview it. You can then enter the width and height (default is 800×1200), choose the format you want, and click Resize Image. Within seconds, you get a download link for your new image.
