FAQ
Do you upload my images?+
No. Watermarking runs entirely in your browser. Your files never leave your device.
Can I use a logo image as a watermark?+
This tool supports text watermarks. Image/logo overlays may arrive in a later update.
Will the watermark be baked into the file?+
Yes. After download, the text is part of the pixels — it cannot be removed easily.
