Image Watermark Tool is an online image watermark coding tool that can add watermarks to your pictures on local devices without any network connection. It supports various adjustments such as watermark transparency, watermark spacing, watermark size, watermark gradient, and so on. This is to protect your sensitive documents (such as ID card, driver's license, passport, etc.). The most important thing is that your image will not be sent to any server. All operations are completed in the local browser, or you can build your own.
