6. Frequently Asked Questions (FAQ)

1. How do I add a logo to my photo?

Simply upload your main photo, then switch to the "Logo Image" tab in our editor. Upload your logo file (PNG, JPG, or WEBP). You can then resize it, adjust transparency, and drag it to the perfect spot.

2. Will the watermark lower my image quality?

No. We use advanced backend processing to merge the watermark. The final output maintains the original resolution and color depth of your source image.

3. Can I make the watermark transparent?

Yes. The "Opacity" slider gives you full control. Set it to 50% or lower for a subtle "ghost" effect that protects the image without distracting the viewer.

4. What formats are supported?

You can upload PNG, JPG, JPEG, WEBP, GIF, and BMP files. The tool typically exports in high-quality JPG or preserves the original format where possible to ensure compatibility.

5. Is my data secure?

Security is built into our architecture. We process images in a temporary, isolated session. Once you download your result, the files are permanently deleted from our system. We do not store or sell your photos.

6. Is this tool really free?

Yes. It is free forever. There are no watermarks from *us*—only the watermark *you* choose to add. No email sign-up is required.

7. Can I protect my image with a tiled pattern?

Yes! Check the "Tiling Pattern" box in the tool. This repeats your watermark across the entire image diagonally, offering maximum protection against cropping.

8. Does it work on iPhone and Android?

Absolutely. The tool is designed with a "Mobile-First" approach. All touch gestures work natively, making it easy to watermark photos directly from your camera roll.

9. How do I rotate the watermark?

Use the "Rotate" slider to spin your text or logo 360 degrees. A slight diagonal rotation (e.g., 45 degrees) is popular for copyright notices.

10. What is 'Stroke' on text?

Stroke (or outline) adds a border around your text characters. This feature is crucial if your image has mixed dark and light areas, ensuring your watermark is always visible.
