FAQ
Is image watermarking really free?
Completely free. All processing happens in your browser, no server costs.
Does it support Chinese watermark text?
Yes. We use a system font stack including PingFang SC and Microsoft YaHei, so Chinese renders cleanly without garbled characters.
Are my images uploaded to a server?
No. All images are processed locally in your browser and never leave your device—ideal for sensitive documents like ID cards.
