Annotate a JWW drawing
Mark up a JWW drawing right in your browser. Draw lines and shapes, drop in text notes, and highlight areas that need attention, then export the marked-up drawing to share with your team. Nothing is installed and nothing leaves your device. Drop a .jww file below to get started.

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.
