Position guide

Choose a position on the 9-grid. Center works for maximum protection; corners are less intrusive.

  • Center: Maximum protection, covers subject.
  • Corners: Subtle, stays out of the way.
  • Edge centers: Balanced protection and visibility.

Tips

  • Use 40–60% opacity for subtle branding.
  • White text works on dark images; dark text on light images.
  • Larger font sizes are harder to crop out.
  • Everything runs on-device; your photos never touch a server.

Protect your images with watermarks

Watermarking deters unauthorized use of your photos by making the source clear. Our tool draws text directly onto the image using Canvas, with full control over placement, size, opacity, and color. Batch-process entire folders of images and download them as a ZIP — no server uploads, ever.

Upload any number of photos.

2. Customize

Set text, position, size, and opacity.

3. Download

Save individually or as a ZIP batch.

Frequently Asked Questions

How do I add a watermark?

Drop your images into the upload area, type your watermark text, choose a position from the 9-grid selector, adjust font size and opacity, then click "Add Watermark". The tool draws your text on a semi-transparent overlay using the Canvas API and lets you download the result immediately.

Can I watermark multiple images at once?

Yes. Drop multiple images into the queue and click "Add Watermark". Every image gets the same watermark applied, and you can download them individually or as a single ZIP archive. There is no limit on batch size.

Can I change the watermark position?

Yes. The 9-grid position selector lets you place the watermark at any corner, edge center, or dead center of the image. Choose the position that best protects your image without obscuring important content.
