Free Image Watermark Tool — Add Watermarks to Photos Online

Protecting your images from unauthorized use is essential — whether you're a photographer, designer, or content creator. theimgapp's Watermark tool lets you add text watermarks to any number of images instantly, with full control over placement, opacity, color, and size.

Why Watermark Your Images?

• Copyright protection: Discourage unauthorized copying and distribution

Watermark Best Practices

Placement

• Bottom-right: Most common, least intrusive
• Center: Maximum protection, most visible (best for preview images)
• Diagonal across: Common for stock photography previews

Opacity

• 20-40%: Subtle branding that doesn't distract from the image
• 50-70%: Visible protection while still showing the image
• 80-100%: Maximum protection for preview/proof images

Text Content

Common watermark text patterns:

• © 2026 Your Name
• yourwebsite.com
• SAMPLE or PROOF for preview images
• Your Brand Name

Tip: Keep watermark text short and readable. Long text becomes illegible at small sizes.

Other Ways to Protect Your Images

Beyond text watermarks, theimgapp offers additional tools:

• Text Behind — Place text behind the main subject for a creative effect
• Image Overlay — Overlay a logo image on top of your photos
• Metadata — View and manage image metadata including copyright information

FAQ

Can I add a logo/image watermark instead of text?

The Watermark tool is text-based. For image-based watermarks (logos), use the Overlay tool to place your logo on top of images.

Will the watermark reduce image quality?

The watermark is composited during processing with minimal quality impact. The output maintains the same resolution and format as the input.

Can I watermark multiple images at once?

Yes. Upload up to 50 images and the same watermark settings will be applied to all of them. Download the results as a ZIP.

Can I remove a watermark later?

No — watermarks are permanently embedded into the image. Always keep your original unwatermarked files safe.

What's the best color for watermarks?

White with 30-40% opacity works well on most images. For light images, try dark gray or black. Use the color picker to find what works best.
