Watermark an image
Put a semi-transparent watermark on your image: your own wording at the opacity and position you want, or a second image such as a logo with transparency.

Questions people ask
- Will my image stay in the same format?
- Yes, wherever the format can carry the result: a PNG comes back a PNG (with its transparency intact), a JPEG a JPEG, a WebP a WebP. There is no hidden conversion to something else. Because the pixels changed, the file is re-encoded by its own format , that is inherent to adding a mark, not an extra loss step.
- Text or logo watermark?
- Both. Type a wording and it is drawn with a clean bundled font, auto-sized to about 60% of your image and placed where you ask. Or upload a picture with transparency (a logo PNG is ideal) in the second slot and it is used as the watermark instead, scaled to at most 40% of your image with its aspect ratio untouched.
- What happens to transparency?
- It is handled as data. On PNG and WebP the overlay blends into existing alpha channels; on JPEG, a format with no alpha channel at all, the watermark composites onto the visible pixels, so what you see is the same either way. Animated images are refused outright rather than quietly flattened to a single frame.
- My phone photo lies sideways. Where does the mark go?
- Where you see the image. Orientation signals in the file are applied first, so the wording falls on the picture as your viewer displays it, and the output states its orientation in plain pixels rather than trusting a header next time.
- How strong should the watermark be?
- Opacity is yours: 30-ish is the usual readable-but-understated mark, 10 is a whisper and 90 is nearly solid ink. A watermark advertises ownership, it is not a technical lock, and anyone with an editor can remove or crop around an open mark.
- What happens to my files?
- The upload is deleted as soon as processing finishes; the watermarked image stays available for about 10 minutes and is then deleted automatically.
