Loading the tool…
To add a watermark to an image, add your photos, choose Text or Logo, set the size, opacity, rotation and position (or tile it across the image), check the live preview and press Apply. The same watermark is stamped on every photo in your browser; nothing is uploaded.
Put your name or logo on photos before you share them. Choose text or an image, fine-tune the size, opacity and angle, and place it in a corner, the centre, or repeated across the whole picture. It is a free tool from Websolindia, a New Delhi website design and SEO company that builds fast, image-optimised websites.
Unlike most online image tools, this one does not upload your pictures. Your browser decodes each image, applies the edit with our own pixel code and shows a live preview before you download. You can process up to 30 images at a time and download them one by one or together as a ZIP.
Once your image is ready, you may also want the Add Border to Image Online, the Rotate Image Online or the Round Image Corners. All of our free image tools are listed in the Image Editing Tools Online collection and the Websolindia Image Converter.
Use this table to choose settings with confidence.
| Setting | Effect | Tip |
|---|---|---|
| Opacity 30–60% | Visible but unobtrusive | Good default |
| Opacity 70–100% | Strong, hard to miss | Use for 'SAMPLE' stamps |
| Tile | Repeats across the image | Hardest to crop out |
| Rotation −30° | Diagonal stamp | Classic 'draft' look |
| Margin | Distance from the edge | 3% keeps it off the border |
This is exactly what happens to your image, with no hidden step. You can check that nothing is uploaded by watching your browser's network tab while you use the tool.
| Step | What happens |
|---|---|
| 1. Read and decode | Each photo is decoded; camera orientation is applied. |
| 2. Make the watermark layer | Text is drawn on a transparent canvas with your font, colour and optional outline; a logo is scaled to your chosen percentage of the photo width. |
| 3. Rotate | The layer is rotated by your angle, with the canvas enlarged to fit. |
| 4. Place it | One of nine anchor positions with your margin, or a staggered grid at 1.8 × the layer size for tiling. |
| 5. Blend and save | The layer is composited over the photo: result = layer × (α × opacity) + photo × (1 − α × opacity); the file is saved in your chosen format. |
| Setting | Default | Choices | What it does |
|---|---|---|---|
| Watermark type | Text | Text; Logo or image | |
| Watermark text | © Your Name | Any text | |
| Font | Sans-serif | Sans-serif; Serif; Monospace; Rounded; Bold display | |
| Bold | On | On / Off | |
| Text colour | #ffffff | Any colour | |
| Dark outline (easier to read) | On | On / Off | |
| Text size (% of image width) | 8 | 2 to 40 | |
| Logo or image file | None | Choose a file | A PNG with a transparent background works best. |
| Logo size (% of image width) | 22 | 3 to 80 | |
| Opacity | 60 | 5 to 100 | |
| Rotation (degrees) | 0 | -90 to 90 | |
| Position | Bottom right | Top left; Top centre; Top right; Middle left; Centre; Middle right; Bottom left; Bottom centre; Bottom right; Repeat across the image | |
| Margin from the edge (%) | 3 | 0 to 15 | |
| Save as | Same as the original | Same as the original; PNG (keeps transparency); WebP (smaller, keeps transparency); JPG (smallest for photos) | |
| Quality | 92 | 1 to 100 | Used for JPG and WebP output. 85–92 suits most images. |
| What | Formula | Notes |
|---|---|---|
| Text size | photo width × size % | Scales with each photo, so batches look consistent. |
| Margin | shorter side × margin % | Distance from the edges. |
| Blend | layer × a + photo × (1 − a), a = α × opacity | Per colour channel. |
| Component | Role | Where it runs |
|---|---|---|
| Browser text rendering | Draws the text layer | Your browser |
| Our compositor | Alpha blending and tiling | Your browser |

Yes. The same watermark is applied to every photo, scaled to each photo's size, and you can download a ZIP.

Use the dark outline option for light text, or choose a colour that contrasts with your photos.
Yes, with the Add Border to Image Online.
Yes. It is free, needs no sign-up, adds no watermark and has no daily limit. It is provided by Websolindia.
No. Your images are read and processed inside your browser on your own device. They are never sent to Websolindia or anyone else, which is why the tool is safe for private photos.
No. New files are created from the pixels, so camera details, GPS location and other embedded metadata are not copied. Keep your originals if you need that information.
Up to 30 images per batch and 150 MB per image. Images above roughly 120 megapixels are declined with a clear message rather than freezing your browser.
Current versions of Chrome, Edge, Firefox and Safari on computers, phones and tablets. Large images and AI or AVIF features run faster on a computer.
