Brand your photos and discourage copying

A visible watermark tells people who made an image and makes it less tempting to reuse without credit. Add a line of text such as © 2026 Your Name or upload your logo, then set the size, opacity, angle and position with a live preview.

Choose a single mark in any of nine positions, or a tiled pattern that covers the whole picture — harder to crop out. Load many photos at once and the same watermark is applied to all of them at full resolution, downloaded together as a ZIP.

How to watermark photos

  1. 1

    Add your images

    Select one or many photos. Use the arrows to preview each one.

  2. 2

    Create the watermark

    Type your text (with font, colour and outline) or upload a logo — a transparent PNG works best.

  3. 3

    Place it

    Pick a corner or the centre, or switch to a tiled pattern. Adjust opacity, size and rotation.

  4. 4

    Download

    Save one image, or all of them as a ZIP.

Key features

  • Text or logo

    Use your name, website or brand logo.

  • Nine positions or tiled

    A discreet corner mark or full coverage.

  • Readable on any photo

    An optional outline keeps light text visible on bright areas.

  • Scales with each image

    Size is relative to the photo width, so the mark looks the same on every size.

  • Batch and private

    Watermark hundreds of images without uploading them.

Common uses

  • Photographers: Share previews with clients without giving away clean copies.
  • Online sellers: Mark product photos so competitors can't reuse them.
  • Documents and ID copies: Add a note such as “For bank KYC only” to a copy of an ID card.

Tips and good to know

  • Opacity around 40–70% is visible without ruining the photo.
  • A tiled watermark at an angle is much harder to crop or clone out than a small corner mark.
  • Watermarking PDFs? Use the PDF Watermark tool.
  • Remove hidden location data before sharing with the Image Metadata Viewer.

Frequently asked questions

Can I add my logo as a watermark?

Yes. Switch to Logo / image and upload your logo; transparent PNG logos give the cleanest result.

Can I watermark many photos at once?

Yes. Select several images and they are all watermarked with the same settings and downloaded as a ZIP.

Will the watermark reduce image quality?

No. Your photos keep their original resolution and format; only the watermark is added.

Can a watermark be removed?

Determined people can sometimes edit out a small corner mark. A tiled pattern across the whole image is far more difficult to remove.

Is it safe for private photos?

Yes. Everything runs in your browser; the images are never uploaded.
