Protect your images with a custom watermark
The Image Watermark tool stamps your JPG, PNG or WebP pictures with text — your name, brand, handle or copyright notice — positioned exactly where you want it. Control the size, colour, opacity and placement so the mark is clearly visible to would-be thieves but never obscures the image itself.
Publishing photos online without a watermark is an open invitation for uncredited reuse; a subtle, well-placed mark makes your images self-attributing as they travel. The tool applies the watermark as part of the image pixels, so it survives downloading, screenshots and re-uploads to other platforms.
Watermarking runs entirely in your browser: your originals — and their protected versions — never leave your device. Batch-apply the same mark across up to twenty files in one pass, and combine with the Image Compressor to publish protected, fast-loading images in one workflow.
Like every Piclizer tool, this one runs entirely in your browser — your files stay on your device.
