A visible label, not copy protection
A watermark can help viewers recognize the source of an image when it is shared. It does not prevent someone from copying the file, cropping the label, or editing it out. Keep your original and use the watermark as attribution rather than as a security guarantee.
How to add a watermark
- Select an image you own or have permission to edit.
- Enter a short label, such as your name or website. It appears immediately in the preview.
- Adjust the text size, color, opacity, and rotation. Size refers to pixels in the original image, not the displayed preview.
- Drag anywhere on the preview to move the text center. On a phone, use a finger. The horizontal and vertical sliders provide the same control without dragging.
- Download the PNG and inspect the result at the size you intend to share.
Make the label readable without hiding the subject
White text often works on darker areas; dark text is easier to read on light areas. A subtle outline is added to help the label stand out. Lower opacity lets the image show through, but can make small lettering hard to see. For a 2000-pixel-wide photo, try a text size of 60 pixels, then adjust after viewing the exported image.
Position matters
A corner label is less intrusive but easier to crop away. A central label is more visible and may distract from the subject. Leave some space around the text so that letters do not fall outside the image when rotated. The preview is scaled to fit this page; the exported PNG retains the source dimensions.
File size and privacy
PNG keeps transparency and does not use JPEG-style lossy compression. A watermarked PNG can therefore be considerably larger than an input JPG. If you need a smaller copy, use the PNG-to-JPG converter after watermarking, understanding that it replaces transparency with white. Images are processed only in this browser tab.
