What you can do here

  • Draw shapes

    Lines, arrows, rectangles, and circles — plus a freehand pen and a highlighter for marking up areas.

  • Add text notes

    Type notes directly on the drawing, right where you need them.

  • Select & adjust

    Move and resize any annotation with the Select tool, or remove it with the eraser.

  • Style your markup

    Pick the color and line width for every drawing tool.

  • Export with markup

    Download as SVG, PNG, or PDF — your annotations are included in the output. Need the plain drawing as DXF instead? Convert it on the main page.

Why use this tool

Marking up a drawing is usually a hassle

Reviewing a drawing usually means printing it out, marking it up by hand, and scanning it back in, or describing changes over email and hoping nothing gets lost along the way.

Draw directly on the drawing, in your browser

This tool opens your drawing directly in the browser and lets you draw, write notes, and highlight sections on top of it, without changing the original file. When you're done, export the marked-up view as an image or PDF to send back.

Who it's for

Useful for site supervisors marking up plans in the field, engineers flagging issues for a colleague, or anyone who needs to review a drawing and share feedback quickly.

Why do it here

Everything runs locally in your browser. Your drawing is never uploaded to a server, so it works for confidential or client work, and there's nothing to install or sign up for.
