Watermark Studio – Protect Your Images in Seconds

Watermark Studio is a fast, privacy-friendly watermarking tool that runs entirely in your browser. Add a text or logo watermark, fine-tune its size, opacity, and rotation, choose between tiled or corner placement, and export a crisp PNG. Need to watermark many files? Use the built-in Batch Process to export a ZIP of images in one go. No files ever leave your device.

Key Features

  • Live preview: What you see on the canvas is what you download.
  • Accurate positioning: Center, corners, or Tiled mode across the whole image.
  • Full control: Opacity, size, rotation, and edge offsets.
  • Text or logo: Use a typed text watermark or upload a PNG/SVG logo.
  • Batch mode: Process many images and download them as a single ZIP.
  • Presets: Save and reuse your favorite settings for repeat work.
  • Client-side: Images never upload to a server; everything happens via Canvas in your browser.

How to Use

  1. Load an image: Upload your photo or pick a sample from the dropdown.
  2. Choose watermark type: Upload a logo (image) or enter Text Watermark.
  3. Adjust style: Select text style (simple, bold, shadow, outline) and color; or tweak logo size.
  4. Place the watermark: Pick a position (center/corners) or select Tiled for repeated marks. Use offsets for fine alignment.
  5. Fine-tune: Set opacity and rotation until it feels right.
  6. Download: Click Download Image to save a PNG.

Batch Watermarking

Open the Batch Process tab, select multiple images, then click Process Batch. When finished, use Download All as ZIP to get everything at once. Batch mode applies your current watermark style and placement to every file.

Tips for Best Results

  • Use a transparent PNG logo for clean overlays.
  • Tiled mode offers strong protection for social sharing.
  • For small photos, reduce size and rotation to keep text sharp.
  • Save a Preset for each brand or campaign to speed up recurring work.

Privacy & Performance

This tool is 100% client-side. Your images and watermarks are processed locally via Canvas — nothing is uploaded or stored remotely.
