What is image watermarking?
Image watermarking is the practice of overlaying a semi-transparent logo, text, or pattern onto photos to assert ownership and discourage unauthorised reuse. Photographers, e-commerce sellers, and content creators use watermarks to protect their work before sharing it online.
SimpleTool's Image Watermarker applies your watermark in bulk — up to 500 photos in a single pass — entirely in your browser. Your photos and logo are never uploaded to any server. The output is standard JPG, PNG, or WebP files you can share anywhere.
Who needs bulk watermarking?
Product photographers
You finished a 200-photo product shoot and need to send proofs to the client. A consistent watermark protects every image before it leaves your hard drive.
Etsy & eBay sellers
Competitors copy your product photos and undercut your listings. A tiled watermark makes stolen images unusable without buying the originals.
Wedding & portrait photographers
You share a proof gallery with 300 photos. Watermarks prevent social media sharing of unpurchased prints while letting clients browse and choose.
Stock photo contributors
You preview your work on a portfolio site but need watermarked versions for public display and clean originals behind the paywall.
Real estate agents
You watermark 50 property photos with your agency logo before uploading to MLS and Zillow so every listing carries your brand.
Social media content creators
You add a subtle handle or website URL to every image post so viewers know the source even when screenshots circulate without credit.
