How to Add Text to Images Online — Captions, Titles, and Watermarks
Add custom text overlays to your images with control over font, size, color, and position.
When to Add Text to Images
- Adding captions to photographs
- Creating social media graphics with quotes
- Adding title text to presentation slides
- Watermarking images with your name
- Creating memes or informational graphics
Text Customization Options
Font and Size
Choose from system fonts and adjust size relative to the image dimensions. Larger text for headlines, smaller for captions.
Color and Opacity
Pick any color for your text. Adjust opacity for watermark-style text that does not obstruct the image.
Position
Place text at predefined positions (top, center, bottom, corners) or drag to a custom location.
Background
Optionally add a semi-transparent background behind the text for better readability over busy images.
Tips for Readable Text
- Contrast — Use light text on dark images, dark text on light images
- Size — Make text large enough to read on mobile screens
- Background — Add a semi-transparent overlay behind text for busy backgrounds
- Fonts — Use bold or semi-bold weights for better legibility at small sizes
- Margins — Leave padding around text so it does not touch the image edges
