Free Online Image Watermark Adder
Add text or a logo watermark to photos with position and opacity controls.
Text watermarks are drawn with a slightly bold font. For a logo, a PNG with a transparent background gives the cleanest result. Increase the padding to keep the mark away from the edges.
About the Image Watermark Adder
A watermark helps people find the original source of a photo and makes casual copying less attractive. This free tool lets you add either a text watermark or a logo image to a JPG, PNG, or WebP photo. Choose one of nine positions, then fine-tune the size, opacity, rotation, and padding until the mark is visible without taking over the picture. The preview is rendered on a canvas at the full image size, so what you see is what you download. All processing happens locally in your browser, and the original file is never uploaded.
Text watermarks
Text mode is ideal for copyright notices, photographer names, brand names, and social media handles. The size control works as a percentage of the image width, which means the mark stays proportionate whether the photo is 800 pixels or 6000 pixels wide. White text works on dark photos and black text works on bright ones; a mid-gray or brand color can be a good compromise. Because the text is re-measured against the image, very long strings are automatically reduced so they do not run off the edge.
Logo watermarks
Logo mode accepts a PNG, JPG, or WebP image and scales it to a percentage of the photo width. A transparent PNG is the best choice because it blends naturally over the photo. Position the logo in a corner for a subtle brand mark or use the center position with low opacity for a stronger protective watermark. Rotation is useful for diagonal marks that are harder to crop out, and padding keeps the mark clear of the image border.
Frequently asked questions
Can a watermark be removed?
Any visible watermark can be removed with enough effort and image editing skill, especially if it sits over a plain background. A watermark discourages casual reuse and identifies ownership, but it is not a technical copy-protection measure.
Does the watermark reduce image quality?
Only the watermarked pixels are changed. The rest of the image is redrawn at its original resolution. Choosing JPG re-encodes the whole image, so use a high quality setting if the source is a JPG.
Why does my transparent logo look different?
Very dark or light logos can disappear against similar parts of a photo. Try a different position, add a little rotation, or use a logo with a subtle outline or contrasting color.
