How to Add a Text Watermark to a Photo Online
You want your name on a photo before it goes online. Image Watermark lets you type the text and see the result live, but there is one default to change before you download.
Type your text, choose position, size, opacity and colour, then download the watermarked copy.
Stamp your name on a photo
- Open Image Watermark and add a JPEG, PNG or WebP with Select Image.
- Replace the text first. The Watermark text box starts with "© LovePDFImg". Type your own name, handle or notice, such as "© Your Name 2026".
- Choose a Position: Bottom Right (the default), Bottom Left, Top Left, Top Right, or Center (diagonal).
- Adjust Font size (12 to 120, default 32), Opacity (10 to 100%, default 50) and Color (a colour picker, white by default). The preview updates as you change each setting.
- Press Download Watermarked Image. The file is saved as
photo-watermarked.jpg, in the original format.
Corner or diagonal?
Corner positions keep the stamp out of the way. It sits a margin in from the edges, and that margin grows with the font size, so large text still has some breathing room. The trade-off is that a corner stamp can be cropped off. A thief with a crop tool removes it in seconds.
The Center (diagonal) option writes the text across the middle of the picture, tilted upward at 30 degrees. It is much harder to crop out, and it also spoils the picture more. Use it for proofs, previews and stock samples that you do not want used without payment, and use a corner for credit lines on pictures you are happy to have shared.
Settings that work together
| Goal | Position | Opacity | Size |
|---|---|---|---|
| Discreet credit | Bottom Right | 50 to 70% | Small, about 3 to 5% of the image width |
| Proof for a client | Center (diagonal) | 30 to 40% | Large, so it spans the frame |
| Social media post | Bottom Left or Right | 60% | Readable on a phone screen |
These are starting points. Because font size is in pixels of the picture, a stamp that looks right on a 1000-pixel image will be tiny on a 4000-pixel one. Check the preview on your actual image rather than reusing numbers from another file.
Choosing the colour
White at 50 percent is the default and works on dark and mid-tone areas. On a bright sky or snow it nearly disappears, so switch to a dark colour. The tool applies a single flat colour, so on a mixed background a mid-tone grey tends to be readable on both light and dark areas. Look at the corner you are stamping, not at the picture as a whole.
What to write in the watermark
Keep it short and recognisable. A name with a copyright symbol and a year is the classic form, for example "© Asha Rao 2026". A website or social handle works if you want viewers to find you. Long sentences clutter the picture and become unreadable on a phone. Avoid putting contact details such as a phone number or home address in a public image.
A copyright notice on the picture is a courtesy and a deterrent. It does not by itself create rights, and the legal position differs between countries, so if protection matters, seek proper advice instead of relying on a stamp.
A sensible routine for a set of photos
- Resize first with Resize Image to the size you will publish, since the stamp is sized in pixels.
- Stamp one image and judge it at the size viewers will see it.
- Repeat the same text, position, size, opacity and colour for the rest, so the set looks consistent.
- Keep the unstamped originals in another folder.
What this tool does not do
- Text only. There is no logo or image watermark option.
- One watermark per run. Each image is processed one at a time. For many photos, repeat the same settings.
- Not tamper-proof. A watermark deters casual copying and records credit. A skilled editor can remove or paint over it, especially a corner one on a plain background.
- No undo after saving. Keep the original photo.
Before publishing, view the result at the size a visitor will see it. A watermark that is crisp in the full-size preview can be unreadable once the picture is shrunk to a thumbnail, and one that is clear in a thumbnail can look heavy at full size. Adjust until both work.
Quality, size and metadata
The stamp is drawn on the picture and the file is saved again. JPG and WebP are saved at 92% quality, so a very small loss is possible, and PNG stays lossless. Pixel dimensions do not change. Embedded camera tags are not copied, so GPS location is dropped. That is a useful side effect, covered in removing EXIF data from photos. If you need a smaller file afterwards, use Compress JPG, and see shrinking images for upload limits.
For PDFs instead of photos
Documents use a different tool. PDF Watermark stamps every page, and how to add a watermark to a PDF explains its settings. If your picture is a scan that will be sent as a document, you might first turn it into a PDF with Images to PDF.
Processing happens in your browser. The photo is not uploaded.
Frequently Asked Questions
Why does my watermark say "© LovePDFImg"?
That is the default text in the box. Replace it with your own name or notice before downloading.
Can I use a logo image as the watermark?
No. The tool supports text only.
What does Center (diagonal) do?
It writes the text across the middle of the picture, tilted upward at 30 degrees, which is harder to crop out than a corner stamp.
Will the watermark stop people copying my photo?
It discourages casual copying and shows credit, but it can be removed by a skilled editor. Do not rely on it for strong protection.
Does it change my image size or quality?
Dimensions stay the same. JPG and WebP are saved again at 92 percent quality, and PNG stays lossless.
Is the photo uploaded?
No. The watermark is drawn in your browser.
