Why Add a Watermark to Your Images?
A watermark is text or a logo overlaid on an image to assert ownership, brand attribution, or confidentiality. Photographers add watermarks to portfolio images shared online to deter unauthorized commercial use. Businesses stamp "CONFIDENTIAL" or "DRAFT" on documents and mockups before sharing with external parties. Designers add their brand name to client previews so work can't be used before payment is received.
Unlike cloud-based watermarking tools that upload your image to a remote server — which is a serious privacy concern when the image contains proprietary designs or unreleased work — Edita's watermark tool processes everything locally in your browser. Your original image never leaves your device.
How to Add a Watermark
- Upload your image. Select a JPG, PNG, or WebP file.
- Enter your watermark text. Type your name, brand, copyright notice, or status label.
- Adjust position, opacity, and size. Place it at a corner, center, or across the full image as a tiled pattern.
- Download the watermarked image. Output is generated instantly in your browser.
Privacy Advantage
Most watermarking tools require uploading your image to their server. If you're watermarking a pre-release product photo, an unreleased design mockup, or a client's confidential document, that upload is a security risk. Edita eliminates that risk entirely — processing happens in browser memory using the Canvas API, and no data is transmitted anywhere.

After watermarking, compress the image before sending. If you need the watermarked image in a different format, use the Image Converter.
