ADD TEXT TO IMAGE
Put a caption, watermark, or label on a picture — position, colour, size and outline.
Size and outline width are percentages of the image, so the caption looks the same whether the photo is 800px or 4000px wide.
This tool runs entirely in your browser. Your images are never uploaded, so nothing is queued, logged, or retained.
Why an Outline Matters More Than Colour
White text is unreadable over a bright sky and black text disappears into shadow, which is why almost every caption you have seen on a photograph carries a contrasting outline. A stroke of one or two pixels against the fill colour keeps text legible over any background, regardless of what is behind it — the reason subtitles and meme captions have used that exact treatment for decades. This tool turns the outline on by default.
Nothing Leaves Your Device
This tool is drawn entirely on a canvas inside your browser. Your images are never uploaded, which means they are never queued, logged, or retained — and the tool keeps working with your network disconnected.
Key Features
- Nine-point positioning plus fine offset control
- Contrasting outline enabled by default, with adjustable width
- Font size expressed as a percentage of image height, so it scales with the picture
- Multi-line text with adjustable line spacing and opacity
