Can I watermark multiple images at once?

For single images, use this dedicated watermark tool for the best positioning and preview experience. For watermarking many images with the same settings, use the Batch Image Processor, which supports watermark overlays as part of the batch processing pipeline. Both tools apply the watermark locally in the browser without uploading your images.

What types of watermarks can I add?

The tool supports both text watermarks (custom text, font, size, color, opacity, rotation) and image watermarks (upload a logo PNG with transparency). Text watermarks can be positioned at preset locations (corners, center, tiled) or placed with custom coordinates. Image watermarks maintain the transparency of the source PNG, making them ideal for logo overlays that blend naturally with the photo.

Are my images uploaded to a server when adding a watermark?

No — the watermark is composited entirely in the browser using the HTML5 Canvas API. Your source images and the watermark graphic are drawn together on an off-screen canvas, and the merged result is exported locally for download. Neither your photos nor your logo or brand assets are transmitted over the network.

What opacity should I use for a watermark?

For deterrence with minimal visual intrusion on a portfolio or preview site, 20–30% opacity is the standard range — visible enough to identify and deter theft, subtle enough not to obscure the work itself. For explicit copyright marking on sample images sent to clients, 40–60% opacity is more appropriate since legibility matters more than aesthetics. Avoid opacity below 15% as the watermark becomes too easy to overlook or remove.

What is Watermark Tool?

The watermark tool overlays a custom text string or uploaded image watermark onto any JPG, PNG, or WebP photo, with full control over position, opacity, size, font, color, and rotation — and outputs a watermarked image ready for distribution. Add watermark functionality protects intellectual property, asserts brand ownership, and deters unauthorized reuse of photography, design work, and digital art. The watermark is composited in the browser and exported as a flattened image, ensuring the overlay is permanently embedded in the output file.

Why use Watermark Tool?

Browser-based watermarking eliminates the need for batch watermark plugins or desktop software, making it practical for individual photographers and small businesses to protect every image before publishing. Customizable opacity settings let you strike the right balance between visibility (deterring theft) and unobtrusiveness (not obscuring the subject), while tiled watermark mode provides comprehensive coverage against cropping attacks. Since files are processed locally, the unwatermarked original never leaves your device — only the protected output is downloaded.

How it works

Stock photographers watermark preview images with their studio name and copyright notice before submitting to microstock agencies or sharing proofs with clients. Wedding photographers add a subtle logo watermark to gallery previews shared on social media to drive traffic back to their portfolio without obscuring the images. Digital artists and illustrators add text copyright watermarks to artwork shared on social platforms to establish authorship and discourage unauthorized commercial use.

Pro Tip

Place watermarks over areas of high detail — faces, backgrounds — rather than in corners alone, since corner watermarks are trivially removed by cropping. For the most theft-resistant protection, use a diagonal tiled watermark at 20–30% opacity, which covers the entire image while keeping it clearly viewable for legitimate use.

Frequently Asked Questions

A well-placed watermark significantly increases the effort required to remove it, deterring casual theft. A corner watermark is relatively easy to crop away; a tiled or centered watermark over the subject is much harder to remove without visibly damaging the image. For the strongest protection, use a semi-transparent tiled watermark at 20–30% opacity that covers the entire image — AI inpainting tools can still attempt removal, but the effort deters most unauthorized use.
