About Image Watermark Editor

Protect your photos and brand your content without leaving your browser. This tool uses the HTML5 Canvas API to composit your watermark logo (PNG with transparent background) or custom text directly onto your image — all client-side, all private.

Common use cases: adding a copyright logo to portfolio photos, branding product images before posting on Shopee, Tokopedia or Instagram, protecting travel photography, and batch watermarking creative work.

How to Use

  1. Upload your source image (JPEG, PNG, WebP, GIF).
  2. Upload a PNG watermark logo (transparent background recommended), or type text watermark.
  3. Choose a preset position or drag the watermark freely on the preview.
  4. Adjust opacity, size, and margin with the sliders.
  5. Select output format (PNG / JPEG / WebP) and download.
