This free image annotation tool lets you mark up any PNG or JPEG image directly in your browser — no account, no software installation, no cost. Draw arrows, add shapes, drop text labels, highlight key areas, and hide sensitive data in seconds.
Simply upload your image, use the annotation tools to mark it up, and download or share the result. It’s the fastest way to communicate visual feedback without lengthy written descriptions or back-and-forth emails.
How to Use the Free Image Annotation Tool
- Upload your image: Upload your image — drag and drop a PNG or JPEG file into the tool, or click to browse your files. (Supported formats: PNG, JPEG only.)
- Select an annotation tool: Select an annotation tool — choose from arrows, rectangles, circles, freehand drawing, text labels, highlights, or the cover marker to hide sensitive information.
- Mark up your image: Mark up your image — click or draw directly on the image to add your annotation. Reposition, resize, or delete annotations at any time before saving.
- Save and share: Save and share — click the checkmark (Done) button to confirm your annotations. Download the marked-up image as a PNG, or copy it to your clipboard to paste directly into a task, email, or chat.
💡 For the sharpest results, use Google Chrome or another Chromium-based browser. Safari and Firefox may render image captures slightly differently.
