Annotate images for site inspections, repairs, lessons, product feedback, instructions, or everyday communication. Point out what matters, add context, and share an image that's easy to understand. ANNOTATE WITH PRECISION • Add arrows, lines, shapes, and text • Highlight details with Spotlight and Loupe • Show dimensions and angles with measurement tools • Draw directly when a quick sketch works best • Snap to 0°, 45°, 90°, or 180° so every line stays straight • Align shapes on an adjustable grid, or start from a blank A4 page PROTECT AND PRESENT • Blur or pixelate private information • Censor a face, a name, a plate, or an address before you send the photo • Use Mosaic for free, and unlock Crystallize, Mezzotint, Pointillize, and Color Halftone with PRO • Erase or crop a freeform area with Lasso Select (PRO) • Crop and combine images to add more context • Organize annotations into editable projects • Export and share the result as an image or PDF TOOLS FOR EVERY DETAIL • Create lines, curves, arrows, rectangles, ovals, rounded rectangles, triangles, parallelograms, polygons, arcs, coordinate shapes, rings, and freehand drawings • Use unlimited vertices in polygons, lines, and curves • Select Multiple shapes to move, copy, or delete them together, and Group them (PRO) to keep them as one • Customize arrowheads, line styles, width, size, color, font, dash pattern, fill, and opacity • Add plain text, comic speech bubbles, pointer text, zigzag bubbles, and thought bubbles • Use hundreds of icons, insert images, and import your own fonts • Zoom and pan with precision and use a finger-following loupe • Work in portrait or landscape with automatic rotation and dark mode • Make collages or stitch multiple photos into a panorama • Add Markdown notes to every project and reopen it anytime • Generate high-resolution images, PDFs with custom templates, or editable project files MADE FOR SCREENSHOTS TOO A screenshot explains a bug, a setting, or a step far better than a paragraph does. Drop an arrow on the button, circle the error, blur the account details, and send it. Annotium keeps the screenshot markup sharp at full resolution, so nothing you point at gets lost when the image is opened on another screen. FROM QUICK MARKUP TO A FINISHED REPORT Start with one arrow. Add measurements, callouts, and notes as the job grows. When the photo set is complete, export every annotated image into a single PDF with your own template, or share the editable project file so a colleague can pick up where you stopped. BUILT FOR REAL WORK Annotium helps contractors, inspectors, technicians, teachers, students, designers, support teams, and anyone who needs to explain something visually. PRO SUBSCRIPTION You can start free with Annotium. An annual PRO subscription unlocks advanced tools and workflows and renews automatically until you cancel.
