Supports PNG, JPG and WEBP images
UtilityGlen's free online image annotator gives you a fast way to draw on images, mark screenshots, add text, place arrows and badges, highlight important details, blur sensitive areas, crop images, rotate or flip them, and export the finished result as PNG or JPG.
Whether you are explaining a bug, reviewing a design, creating a tutorial, documenting a process, giving visual feedback, or preparing a marked-up image for a report, you can do it directly in your browser without installing a separate desktop image editor.
Use simple annotation tools when you need speed, or combine multiple tools when a screenshot or image needs a detailed visual explanation.
Use the pencil tool to circle details, sketch corrections, underline areas, or add freehand notes directly over your image.
Add clear directional arrows when a visual explanation needs an unmistakable focal point.
Hide names, email addresses, account details, private messages, or other information before sharing a screenshot or image.
Add captions, comments, short instructions, labels, and callouts exactly where they belong.
Draw squares, rounded rectangles, circles, and lines to frame the exact area you want viewers to notice.
Emphasize text, objects, interface controls, or important image details while keeping the original content visible.
Drop recognizable status symbols onto an image or drag a badge to create a directional marker. Great for reviews, approvals, corrections, questions, warnings, and visual feedback.
Correct image orientation, mirror the image horizontally or vertically, and crop away unnecessary areas before exporting your final annotation.
No complicated project setup. Open an image, mark what matters, make adjustments, and export the finished version.
Choose, drag and drop, or paste an image.
