One or more JPEG, PNG or WebP images, up to 20 in one run. Mixed shapes are fine: each one gets the same relative mark.

    One JPEG, PNG or WebP logo, used when the type is Logo image. A transparent PNG keeps the photo underneath.

      Preview the first image

      Set the mark and choose images, then preview how it looks on the first one.

      A logo image needs its own file below. A PNG logo with transparent background works best.

      Used when the type is Text. Keep it short; long text is shrunk to fit the width limit.

      The text width or logo width as a share of each image width, so the mark stays proportional across mixed shapes. Tiled marks use the same value for spacing.

      1 is fully solid and 0.05 is nearly clear. Light marks stay readable without hiding the photo underneath.

      Rotates the mark around its own center. Diagonal marks suit tiled placement but are hard to read in a corner.

      A six-digit hex color such as #ffffff for white or #111111 for near black. Used by Text marks only.

      Space between the mark and the image edge for the four corner placements. Ignored by Center and Tiled.

      PNG output ignores this setting because PNG is lossless.

      How to use Watermark Image

      1. Choose your images in the Images field, up to 20 in one run.
      2. Set Watermark type to Text or Logo image, then add the text or logo file.
      3. Pick a Placement, then set Size in percent of the image width and Opacity.
      4. Set the Angle, Text color and Margin if the mark needs them.
      5. Choose an Output format, then select Watermark the images.

      Example: Watermark Image

      Mark two different PNGs with a text watermark.

      You add
      image-1.png and image-2.png in one run. Watermark type: Text. Watermark text: SAMPLE. Placement: Bottom right. Size: 18 percent of the image width. Opacity: 0.35. Angle: 0 degrees. Text color: #ffffff. Margin: 4 percent. Output format: PNG.
      You get
      The result reports that 2 images were watermarked and downloads a zip. Each file keeps its own name with -watermarked added, because the two sources have different names.

      Options

      Size in percent of the image width
      Runs from 2 to 100. The mark is measured against each image separately, so portrait and landscape files keep the same relative mark size. A tiled mark uses this value for its spacing.
      Placement
      The four corners use the margin. Center and Tiled ignore it. A tiled mark covers the whole picture and stops at 400 draws per image.
      Opacity
      1 is fully solid and 0.05 is nearly clear. A light mark stays readable without hiding the photo.
      Margin in percent of the image width
      Space between a corner mark and the nearest edge. It has no effect on the center and tiled placements.

      Per image64 MiB each, 40 megapixels each, 128 MiB total
      One to 20 JPEG, PNG or WebP images per run, 64 MiB each, 128 MiB in total and 40 megapixels per image. Every image is measured before its mark is drawn, so the mark keeps the same share of width across mixed shapes. Tiled marks stop at 400 draws and the spacing grows on very large images. A watermark is a visible mark and does not prevent copying, editing or removal. JPEG has no transparency, so transparent areas become white. Two sources with the same name get a numbered suffix in the ZIP, and a text mark needs text and a six-digit hex color.

      Choosing a placement and a colour

      A corner keeps the subject clear, which suits product shots and listing images. The center sits over the subject and suits a proof you do not want cropped. Tiled marks cover the whole picture. White text disappears against a bright sky, so pick a colour that contrasts with the area under the mark. PNG keeps transparency and ignores the quality setting, while JPEG and WebP use it.

      Questions about Watermark Image

      Does a watermark stop people from using my photo?

      No. It labels the file and makes casual reuse obvious. Anyone can crop around the mark, cover it or edit it, and a simple mark can sometimes be removed automatically. Keep the unmarked original.

      Why is the mark a different pixel size on each image?

      The size setting is a share of each image's own width, so a 1600-pixel-wide photo gets a 288-pixel mark and an 800-pixel-wide one gets 144 pixels. The two marks look the same size in their own pictures even though the images differ in width.

      Why is one file in the ZIP called product-photo-watermarked-2.png?

      Two files in the run shared the name product-photo.jpg. The tool adds -2 to the later entry so the two files cannot collide inside the ZIP.

      Can I watermark a PDF or a video?

      No. This tool takes JPEG, PNG and WebP images only. For a PDF, use the PDF watermark tool.
