Adjust line and text styles for contrast, then export an annotated PNG, JPG, or SVG for review or documentation.
Mark overall width, height, depth, seat height, clearance, wall spacing, or placement notes on a photo or mockup.
Label panel size, safe areas, folds, openings, label placement, or other production notes on packaging visuals.
Communicate part dimensions, spacing, alignment, component names, or revision notes before CAD or production work.
Add manual spacing notes, arrows, labels, and redline-style callouts to screenshots without changing the source design file.
The editor displays values you type. It does not infer real-world measurements from pixels, calibrate image scale, open CAD dimensions, or guarantee manufacturing tolerances. Verify critical measurements in the original design or measurement source.
You can annotate mockups, furniture photos, packaging visuals, product sketches, screenshots, diagrams, and other JPG, PNG, or GIF references up to the tool's file-size limit.
No. You enter verified values manually. A normal image does not contain enough scale information to recover reliable real-world measurements.
Yes, for visual communication and review. For construction, manufacturing, or engineering decisions, keep the authoritative dimensions in the original CAD, drawing, or specification.
No. Editing and export happen locally in your browser.
