How to Add a Watermark to an Image
- 1
Upload your JPG, PNG, or WebP photo by clicking the upload zone or dragging the file directly from your computer or phone.
- 2
Type your custom watermark text (for example, '© Your Studio Name' or 'FOR VERIFICATION ONLY') and select single-corner placement, center placement, or full-image tiled repetition.
- 3
Fine-tune the typography size, text color, and alpha opacity slider (25%–40% is ideal for subtle protection that preserves viewing clarity).
- 4
Inspect the live canvas preview and download your watermarked image at full native resolution in PNG, JPG, or WebP format.
Practical Use Cases
Branding Product & Property Listings
Add your store name or agency handle to original product photography and apartment listing photos so competitors cannot scrape and reuse your catalog assets.
Securing KYC & Identity Document Scans
Overlay a tiled watermark stating 'Submitted only for [Bank/Rental Application] on [Date]' across Aadhaar, PAN, or passport photos to prevent identity reuse.

Technical Specifications & Best Practices
- ✓Use 25% to 40% opacity with white or light-gray text for general photography so the watermark deters theft without ruining the viewer experience.
- ✓Choose 'Repeat across image' when protecting sensitive documents or high-value proofs so the watermark cannot be removed by simply cropping the edges.
- ✓Export as WebP or JPG (85% quality) for fast web publishing, or choose PNG for lossless text edges on graphics and document scans.
- ✓Always keep an unwatermarked master copy archived on your device, as baked-in raster watermarks cannot be stripped later.
