Why Watermark Your Images?

Watermarking protects your work. Whether you're a photographer sharing previews with clients, a designer distributing work samples, or a content creator protecting original images from being reposted without credit — a watermark deters unauthorized use and makes your ownership visible.

The problem: many watermark photo online tools upload your images to a server, which introduces privacy concerns, especially for client photos or unpublished work. ShiftTools adds watermarks using the browser's Canvas API — your images are never sent anywhere.

Step-by-Step: Add Text Watermark to Image Free

  1. Open Watermark Tool on ShiftTools. No sign-up needed.
  2. Upload your images: Drag one or multiple JPG or PNG files onto the tool. All processing stays in your browser.
  3. Choose watermark type: Select "Text" to add text watermark to image (custom message, copyright notice, URL), or "Logo" to overlay a PNG logo image.
  4. Customize: Set font, size, color, opacity, and position (corner, center, tiled). Preview the result in real time.
  5. Apply to all: With batch watermark images enabled, the same watermark settings apply to every image in your batch.
  6. Download: Save individual files or download all as a ZIP.

Tips for Effective Watermarks

  • Use 30–50% opacity for a visible but non-intrusive watermark
  • Place watermarks in the center or across the entire image to prevent easy cropping
  • White text with a subtle shadow is readable on both light and dark backgrounds
  • For product photos, bottom-right corner watermarks are professional and minimal

Frequently Asked Questions

Can I batch watermark multiple images at once?
Yes. Import multiple images and apply your watermark settings to all of them in one step. Download as a ZIP to get all watermarked images together.
Is the watermark permanent?
Yes. The watermark is merged into the exported image. If you need to edit or remove it later, keep your original files — the tool does not modify your originals.
Can I use my own logo as a watermark?
Yes. Upload any PNG file (transparent backgrounds are supported) and position it anywhere on the image at any opacity.
Does the watermark tool work for photos going to clients?
Absolutely. Because processing is entirely local, your client images never touch a third-party server — they stay on your computer throughout.
What formats does the watermark tool output?
Output is JPG or PNG depending on the source file. PNG preserves transparency if your source is a PNG. JPG output uses your chosen quality setting.
