Add Text to Image
Add custom text to any photo or image directly in your browser. Upload an image, type your text, and control the font size, color, position, and outline. Download the result as a high-quality PNG. Your image never leaves your device — everything is processed locally using the HTML5 Canvas API. No login, no watermark, completely free.
How Adding Text to Images Works
This tool uses the HTML5 Canvas API to draw your uploaded image onto an invisible canvas element, then renders text on top of it at the coordinates you specify. The canvas preserves the original image resolution, so your output is the same quality as your input. Text is rendered with anti-aliasing for smooth edges, and the optional outline (stroke) is drawn first as a thicker path behind the fill text, creating the classic bordered text effect seen in memes, thumbnails, and social media graphics.
The position controls use percentage-based coordinates, where 0% is the top-left corner and 100% is the bottom-right corner. This means X Position 50% and Y Position 50% places text at the exact center of the image, regardless of its dimensions. This approach works consistently across images of any size or aspect ratio, making it intuitive to position text exactly where you want it.
Text Rendering on Canvas
Canvas X = Image Width x (X Position / 100)
Canvas Y = Image Height x (Y Position / 100)
Outline: strokeText() drawn before fillText() with larger lineWidth
The canvas renders text at the native resolution of your uploaded image, preserving full quality in the download.
When to Add Text to Photos
Adding text to images is one of the most common image editing tasks. Social media posts with text overlays consistently outperform plain images because they communicate a message instantly without requiring viewers to read a caption. Product images with pricing or feature callouts convert better in e-commerce. Event photos with date and location text become self-contained shareable graphics. Motivational quotes over nature or lifestyle photos are among the most shared content on Instagram and Pinterest.
Readability Best Practices
The most critical factor when adding text to images is readability. White text with a dark outline is universally readable against any background — this is the gold standard used in memes, subtitles, and video overlays. For a more subtle approach, add a semi-transparent background bar behind the text. Keep font sizes large enough to read on mobile screens, where most social media content is consumed. A minimum of 48 pixels is recommended for text that needs to be readable in social media feeds.
Comparison with Desktop Software
Traditional approaches to adding text to images require desktop software like Photoshop, GIMP, or Canva. These tools offer more features but also more complexity, learning curves, and in some cases subscription costs. This browser-based tool is designed for the most common use case: quickly adding readable text to an image and downloading the result. It requires no installation, no account, and produces results in seconds. For professionals who need layer management, blend modes, and advanced typography, desktop tools remain the better choice.
Supported Image Formats
This tool accepts any image format supported by your browser, including JPEG, PNG, WebP, GIF (first frame), BMP, and SVG. The output is always a high-quality PNG file, which preserves text sharpness and supports transparency. If you need a smaller file size, you can convert the PNG to JPG using our companion image conversion tools.
