Why thousands choose this Free Online Bulk Watermark Tool
🔒 Private & secure — zero uploads, zero risk
Your images never leave your device. Period. All watermarking — whether text, logo, or tiled pattern — happens right inside your browser using client-side processing. No uploads, no servers, no snooping. Perfect for protecting sensitive photos, business assets, product shots, or personal memories before sharing them online.
✍️ Add watermark to multiple photos — text or logo, your choice
Why use a separate tool for text and logos? This free online bulk watermark tool handles both seamlessly. Type custom text — your name, brand, website URL, or copyright notice — and tweak the font size, color, and opacity until it looks just right. Or upload your own logo or signature image (PNG with transparency works best) and position it exactly where you want.
📍 Six placement options — including tiled for full protection
Position your watermark anywhere with one click: Top Left, Top Right, Center, Bottom Left, Bottom Right, or Tile (repeated across the entire image). The tile option is perfect for photographers and artists who want to deter unauthorized use without ruining the viewing experience. No guesswork — you see exactly where it will land before you download.
🎨 Fine-tune every detail — size, color, and opacity
A watermark should protect your work without overpowering it. Adjust font size for text watermarks, pick any color using a full color picker, and dial in the opacity slider to make it subtle or bold. For logo watermarks, the opacity control ensures your brand mark sits elegantly in the corner without distracting from the image itself.
📦 Batch watermark maker — protect dozens of images at once
Upload a handful of images or dump an entire folder — we handle it. Apply the same watermark settings across 10, 50, or 100+ photos in one go. Whether you're branding product photos for your Shopify store, protecting a client gallery, or adding copyright to vacation snapshots before posting on social media, it all happens in seconds.
