Annotate Image - Add Labels to Photo

Yes, absolutely. All image annotation happens entirely in your browser using client-side JavaScript. Your image is never uploaded to any server, ensuring complete privacy and security.

Yes, completely free with no registration, hidden fees, or usage limits. Annotate as many images as you need.

Yes, once the page loads, you can annotate images completely offline without an internet connection.

The tool supports all common image formats including JPG, PNG, WebP, and GIF. The output is typically saved as PNG to preserve annotation quality.

Use the X (horizontal) and Y (vertical) coordinate inputs. X=0 is the left edge, Y=0 is the top edge. Adjust the numbers to move the text, or click the image to set coordinates visually (if supported).

Currently, the tool adds one text annotation at a time. To add multiple labels, download the first annotated image, then re-upload it and add the next annotation.

The background color adds a colored box behind your text to improve readability. Use “transparent” for no background, or enter a color name or hex code like “#000000”.

The tool uses a standard sans-serif font for clarity. You can adjust the size (8-200 pixels) to make text larger or smaller based on your image dimensions.

Perfect for adding watermarks, labeling diagrams, creating educational materials, marking up screenshots, adding captions to photos, highlighting features, or preparing images for presentations.

Yes, the tool maintains the original image resolution. The annotation is rendered directly on the canvas, so your final image quality matches the input quality.
