Finally a free watermark tool that actually respects privacy. No uploads, no accounts, and the text customization is better than paid tools.

Frequently Asked Questions

Everything you need to know about image resizing

Can I add watermarks to images in bulk?

Yes. Upload up to 12 images at once and apply the same text or image watermark to all of them in a single step.

What types of watermarks can I add?

You can add text watermarks with full font, color, and style control, or image watermarks by uploading your own logo or graphic. Both types support opacity, rotation, scale, and precise grid-based positioning.

Is this watermark tool really free?

Completely free. No account, no subscription, no hidden fees. Watermark as many images as you need at no cost.

Are my images private when adding watermarks?

Yes, 100% private. All processing happens entirely in your browser — your images never leave your device or reach any server.

How does the position grid work?

The grid system divides your image into a customizable grid (e.g., 3x3 or 5x5). You can activate one or multiple grid cells to place watermarks at those positions. This gives you precise control over watermark placement.

Can I save and reuse my watermark settings?

Yes. All settings are synced to the URL. Simply copy the URL to save your exact configuration, and paste it later to reload the same settings. You can also start from built-in templates.

Which image formats are supported?

You can watermark JPG, JPEG, PNG, and WebP images. The output preserves your original format.

Will adding a watermark reduce image quality?

The watermark is composited onto your image using canvas rendering. The output quality matches your original — no additional compression is applied.
