Tips for Adding Text to Images
- For readability, use a dark background behind text on light images, and a light background on dark images. Adjust opacity for a more subtle look.
- Use larger font sizes (48px+) for bold headlines, and smaller sizes (16-32px) for captions or watermarks.
- The Bottom-Left (BL) and Bottom-Right (BR) positions are popular for watermarks and photo credits.
Frequently Asked Questions — Add Text to Image
Is the add text to image tool really free?
Yes, completely free. No registration, no hidden charges, no watermarks, and no file size limits. All processing happens locally in your browser — your images never leave your device.
How does the text overlay work?
Our tool draws your image on a canvas, then renders your chosen text on top with the specified style — font size, color, background, opacity, and position. The text is rendered using the browser's built-in canvas text API with anti-aliasing for crisp, clear results.
Can I use any font or color?
The tool uses the system's default sans-serif font. You can choose any color using the color picker for both text and background. Opacity can be adjusted from 10% to 100%.
What image formats are supported?
JPG, PNG, WebP, BMP, AVIF, GIF, TIFF, SVG, HEIC and more. The result is saved in your original upload format.
Can I add multiple lines of text?
Currently the tool supports a single text overlay per image. For multiple text elements, you can download the result and run the tool again to add another layer.
Can I use this to watermark my photos?
Yes! The tool is ideal for watermarking. Use a semi-transparent white or gray text at 40-60% opacity in the bottom-right or center position for a professional watermark effect.
How large of an image can I process?
Our tool handles images up to 50 megapixels (50,000,000 pixels total). If your image exceeds this limit, you'll see a warning and can try a smaller version.
