Frequently Asked Questions
Is this tool really free?
Yes, absolutely. The Image Watermark Tool by StudioSEO Tools is completely free to use for adding text or logo watermarks to your images. No registration required, no hidden costs.
Do you upload my images to a server?
No. This tool processes your images locally in your browser using HTML5 Canvas technology. Your images are never uploaded to our servers, ensuring complete privacy and security. Everything happens on your device.
Can I add a tiled watermark across the entire image?
Yes. Enable the "Tiled watermark" checkbox and adjust the tile gap slider to create a repeating watermark pattern across your entire image. This is perfect for protecting images from unauthorized use.
What image formats are supported?
You can upload PNG, JPEG, and WEBP images. For export, you can choose PNG (best quality, supports transparency), JPEG (smaller file size), or WEBP (modern format with good compression). You can also adjust the quality slider for JPEG and WEBP exports.
Can I use my own logo as a watermark?
Yes. Switch to "Logo" mode and upload your logo image. We recommend using a PNG file with a transparent background for best results. You can then adjust the logo size, opacity, rotation, and position to fit your needs.
What's the best watermark position to prevent removal?
For maximum protection, use the tiled watermark feature with moderate opacity (30-50%). This makes it extremely difficult to remove the watermark without damaging the image. For single watermarks, placing them in the center or using a diagonal position works well.
