How to Add a Watermark to Your Photos, One or a Hundred at Once

To watermark a photo for free without uploading it, open it in the AI Web Center image editor, go to Watermark, type your name or choose a logo, and set the position, size, opacity and angle; Tiled repeats it over the whole picture. To watermark many photos, set the watermark up once, then use Convert many images with Add the watermark ticked, and download them all as a ZIP.

Photographers, artists, real estate agents, Etsy sellers: if your pictures go online, they get copied. A watermark won’t stop a determined thief, but it makes clear whose work it is, and it turns a copied picture into an advertisement that points back to you.

Watermark one photo

  1. Open the photo in the image editor and click Watermark.
  2. Type your text, such as © Jane Doe Photography or your website, or click Logo and choose your logo file.
  3. Pick a position: one of nine spots, or Tiled over the whole image.
  4. Set the size (as a share of the photo’s width), the opacity and the angle. Leave Soft shadow on so it reads on light and dark parts alike.
  5. Save.

Because the size is relative to the photo, the mark looks the same on a small phone shot and on a 50-megapixel file.

Watermark a whole set

Set the watermark up once in the editor, then scroll down to Convert many images:

  1. Choose the photos, or a ZIP of them.
  2. Tick Add the watermark from the editor above.
  3. Pick the format and, for the web, a longest side such as 1600 or 2048 pixels.
  4. Click Convert and download the ZIP.

All of this happens in your browser. Your photos and your logo aren’t uploaded anywhere, and the saved copies carry no location or camera data.

Corner or tiled?

  • Corner, small, fairly solid: looks professional, barely gets in the way, and is easy to crop off. Good for a portfolio and social posts.
  • Center, large, see-through: hard to remove, but it dominates the photo.
  • Tiled at an angle: a repeating pattern over the whole image, the way stock photo sites mark their previews. Best for proofs you send a client before they pay.

What a watermark can’t do

Image tools that fill in a removed area keep improving, ours included. Our own image editor has a Remove tool for date stamps and your own old watermarks, and it says plainly to use it only on photos you own or may edit. In the United States, removing a credit or copyright notice to hide infringement is illegal on top of the copyright infringement itself. A tiled mark over detailed parts of the photo remains the hardest to remove cleanly.

The best protection for full-quality files is not to post them at all: share web-sized copies with a watermark, and keep the originals for paying clients.

Key takeaways

  • Text or logo, in a corner or tiled, sized relative to the photo.
  • Set it once and stamp a whole set with Convert many images.
  • Corners look better; tiles protect better.
  • Post web-sized, watermarked copies; keep the originals.

Frequently asked questions

Where should a watermark go?

A small mark in a corner looks professional but is easy to crop off. A larger, semi-transparent mark across the middle, or a tiled pattern, protects better but gets in the way of the photo. For portfolio pieces, a corner is common; for proofs you send to clients before they pay, tiled is the usual choice.

What opacity should I use?

Between 30 and 60 percent for a mark over the photo, so it's clearly there without hiding the picture; up to 80 percent for a small corner mark. Turn on the soft shadow so white text stays readable on light areas.

Does a watermark protect my copyright?

Your copyright exists without one. A watermark makes it obvious who the photo belongs to and how to reach you, which discourages casual copying and helps people find you. In the United States, removing copyright information such as a credit on a photo to hide infringement is itself against the law (17 U.S.C. § 1202).

Can I use a logo with a transparent background?

Yes, a PNG or WebP with transparency works best: only the logo shows, at the opacity you choose. A JPEG logo comes with its white or colored background.
