Free Image Watermark Tool
Protect your images with text or logo watermarks. Customize position, opacity, rotation, and tiling. Process multiple images at once. Everything runs in your browser — your images stay on your device.
How to Use
- Upload images — Drag and drop or click to browse. Supports PNG, JPG, WebP. Multiple files supported for batch processing.
- Choose watermark type — Text watermark with custom font, size, and color, or logo watermark with any uploaded image.
- Adjust settings — Set opacity, rotation, and position. Enable tiling for full-image coverage that resists cropping.
- Download — Export as PNG (lossless) or JPG (adjustable quality). Download individually or batch-download all images.
Watermark Best Practices
- → Use 20-40% opacity for a professional look that protects without distracting from the image.
- → Enable tiling for maximum protection. Single watermarks can be cropped out. Tiled patterns make unauthorized use much harder.
- → Use white text on dark images and dark text on light images. Ensure the watermark is visible regardless of the image content.
Common Use Cases
Adding a faint copyright line to photography before posting to social media, so scraped reposts at least carry attribution. Stamping draft mockups with a "DRAFT — do not distribute" overlay before sending to clients, where the watermark is the friction that keeps a comp from accidentally going to production. Branding product photos for an e-commerce listing with a subtle logo in the corner so the image survives reposting on third-party marketplaces.
Marking exam materials, internal documents, or photos shared with reviewers with the recipient's name, so the source of any leak is identifiable. Adding a tiled diagonal watermark to a portfolio shot specifically to deter unauthorized stock submissions. Batch-processing a wedding gallery so the photographer's name is embedded in every preview before clients download them.
How We Compare
Photoshop, Affinity Photo, and Pixelmator all do watermarking well and offer pixel-precise control. They're the right tool when you need that precision and you're already in the file. For a quick stamp across a folder of fifty images, they're overkill — you'd build a Photoshop action or use the export presets to script it. Mobile apps like iWatermark are convenient on a phone but lock features behind in-app purchases.
This tool focuses on the batch case: drop a folder of images, set the text or logo, adjust opacity and position, and download a ZIP. Everything runs client-side, so originals never leave your device. The output preserves the source dimensions and doesn't re-encode through a low-quality JPG step. For metadata changes alongside the visible watermark, see EXIF viewer.
One pragmatic note: visible watermarks deter casual reuse but don't prevent determined theft — modern AI inpainting models can remove them. For genuinely high-value imagery, layer this with invisible watermarking (steganography) or DMCA-monitoring services, treating the visible mark as the friction layer rather than the protection.
