[Add Watermark to Image](https://edesy.in/tools/add-watermark-to-image) puts your name, website or logo on photos before you share them. Everything runs in your browser, so your photos are not uploaded.

## How to Use

1. Drop one or more JPG, PNG or WebP photos onto the tool.
2. Choose the **Text** or **Logo** tab.
   - **Text**: type in **Watermark text** (it starts as "© Your Name"), set **Font size** and **Colour**.
   - **Logo**: choose a file under **Logo image** and set **Logo size**.
3. Adjust **Opacity** (50% by default) and **Rotation** (-45° to 45°).
4. Pick a **Position**: one of nine spots such as Top left, Centre or Bottom right (the default), or **Tile across image**. Use **Margin** to move a placed mark away from the edge, or **Spacing** to spread tiles out.
5. Click a file name in the list to preview it, then click **Download** for one photo or **Download all (ZIP)** for the batch.

## Things to know

- **Size is relative**: font and logo size are set as a % of image width, so the mark looks the same on photos of different sizes.
- **Output**: downloads keep the original resolution and format. WebP stays WebP where your browser can save WebP (Safari saves PNG instead). The preview is scaled down.
- **Downloads are disabled** until there is watermark text, or a logo has been chosen.
- **File limit**: up to 25 MB per photo.
- **Privacy**: photos and logos stay on your device.

## Tips

- The logo can be a PNG (transparent works best), WebP or JPEG. A transparent PNG looks cleanest.
- For proofs, tile a word such as SAMPLE or DRAFT at around 30-45° rotation so it is hard to crop out.
- White text at 40-60% opacity is visible on most photos without hiding the subject.
