Protect Your Images with Watermarks

Watermarking is essential for photographers, designers, and businesses who share images online. A watermark deters unauthorized use while still allowing your work to be displayed. This tool lets you add professional text watermarks to multiple images simultaneously, saving hours of manual work in photo editing software.

Why Watermark?

In Africa's growing digital economy, content creators and photographers need to protect their intellectual property. Whether you're a Lagos wedding photographer, a Nairobi food blogger, or a Cape Town real estate agent, watermarking your images before posting online helps establish ownership and brand recognition. A subtle watermark can prevent image theft while maintaining visual appeal.

Best Practices

Place watermarks where they can't be easily cropped out — the center or a tiled pattern works best. Use semi-transparent watermarks (20-40% opacity) that protect without obscuring the image. Include your brand name, website, or copyright symbol. For portfolios, a diagonal tiled watermark provides the best protection against unauthorized use.

Frequently Asked Questions

Are my images uploaded to a server?

No. All watermark processing happens entirely in your browser using HTML5 Canvas. Your images never leave your device. This ensures complete privacy and works even without an internet connection (after the page loads).

Can I watermark multiple images at once?

Yes. Select multiple images when uploading, and the same watermark settings will be applied to all of them. Use the "Download All Watermarked" button to process and download each watermarked image.

What image formats are supported?

You can upload PNG, JPG, WebP, BMP, and GIF images. All watermarked images are downloaded as PNG files to preserve quality and transparency.
