Watermark Image
A watermark stamps your name, brand, or copyright notice onto a photo so people know whose work it is and think twice before reusing it without credit. Photographers, marketplace sellers, designers, and social media creators all use watermarks for the same reason: images travel far on the internet, and a small line of text in the corner travels with them. This free tool adds a clean text watermark to any image, directly in your browser.
You control how the mark looks. Type your own text, pick one of five positions, choose any colour, and adjust the opacity and size with sliders. A semi-transparent mark in a corner is the classic choice: visible enough to claim the image, subtle enough not to spoil it. The preview updates as you change every setting, and the download renders at the full resolution of your original photo. The faint dark outline behind the text keeps it readable on both light and dark parts of a picture. Nothing is uploaded; the whole process stays on your device.
How to use
- Click the file box and choose the photo you want to protect.
- Type your watermark text, such as your name, brand, or website.
- Choose a position: one of the four corners, or the centre for a stronger mark.
- Set the colour, then use the opacity and size sliders until the mark looks right.
- Click Download Watermarked Image to save the finished picture as a PNG.
Frequently asked questions
Can a watermark be removed by someone else?
A determined person with editing software can weaken or crop out almost any watermark, so treat it as a deterrent and a credit line, not a lock. Corner marks are easiest to crop, while a larger, more transparent centre mark is the hardest to remove cleanly.
What opacity should I use?
Between 40 and 70 percent works for most photos. Lower values look elegant but are easier to ignore; higher values are clearer but can distract from the image itself. The slider lets you judge on your own photo.
Does watermarking reduce quality?
The photo is redrawn once and saved as a PNG, which is lossless, so the only change is the watermark itself. The output keeps the full width and height of the original image.
Are my images uploaded anywhere?
No. Your photo is drawn and stamped locally in your browser and never leaves your device.
