Add Watermark
To use this tool, simply upload a photo from your gallery or camera, then enter your desired watermark text—for example, “property of ajakteman.com.” Then, adjust the text size using the slider to fit the photo, choose your desired color, and adjust the transparency (opacity) so the watermark isn’t too obvious but remains visible. You can also adjust the angle of the text and the spacing between the patterns so the watermark spreads across the entire image. Once you’re satisfied, click the “Refresh” button to see the results, and press “Save” to download the watermarked photo directly to your device.
Besides protecting product photos from plagiarism, this tool is also useful for marking ownership on personal documents such as ID cards, diplomas, certificates, and more before sharing them online. This way, you can prevent unauthorized individuals from misusing your important images for malicious purposes. The entire process takes place in the browser without sending data to any server, ensuring security and privacy.
This tool can be used on Android, iPhone, and laptops without installing additional applications. The interface is simple, lightweight, and responsive to various screen sizes. You can also use any browser like Chrome, Safari, or Edge. The resulting watermark will automatically adjust to the image size, ensuring it remains clean and proportional on all devices.
