Free Watermark Tool — Add Text Watermarks to Images Online
Add custom text watermarks to any image for free. Control text, font size, opacity, color, and position. Runs entirely in your browser — no upload, no signup, download as PNG.
Skycally's Add Watermark tool lets you permanently stamp any image with a custom text watermark in seconds — directly in your browser. Type your watermark text, customize the font size, opacity, color, and choose from 9 placement positions, then click Apply to see the result and download it as a PNG.
Watermarking is essential for photographers, content creators, and businesses who share images online. A well-placed watermark protects your work from unauthorized use, establishes brand identity, and makes it clear who created or owns the content. With opacity control from 10% to 100%, you can make the watermark subtle and professional or bold and visible depending on your needs.
The 9-position grid covers all corners, all four edges, and the center — giving you precise placement control. Font size ranges from 12px to 120px to accommodate everything from small copyright notices to large prominent branding stamps.
All processing runs locally in your browser using the Canvas API. Your image never leaves your device, making this tool completely private and safe for sensitive or proprietary images. Output is always a full-quality PNG regardless of the input format.
Frequently Asked Questions
Can I change the watermark position?
Yes. A 9-point position grid lets you place the watermark in any corner, along any edge, or in the center of the image.
Can I control the watermark opacity?
Yes. Use the opacity slider to set transparency from 10% (nearly invisible) to 100% (fully opaque).
What image formats are supported?
PNG, JPG, and WEBP are supported as input. The output is always saved as a full-quality PNG.
Will the watermark reduce image quality?
No. The watermark is drawn on a canvas copy of your image at full original resolution. Output PNG quality is lossless.
Can I add an image watermark (logo) instead of text?
Currently the tool supports text watermarks only. For logo/image watermarks, a more advanced tool or desktop software would be needed.
Is my image uploaded to a server?
No. Everything runs locally in your browser using the Canvas API. Your image never leaves your device.
Can I add multiple watermarks?
Currently one watermark is applied per image. For multiple watermarks, apply and download, then re-upload the result to add another.
What font is used for the watermark?
The watermark uses the system sans-serif font (Arial on most devices) in bold style, with a matching font size that you control via the slider.
