Draw on photos: mark up pictures with arrows, notes and measurements
Take a photo of the job, the room or the problem, and draw right on it. Circle what matters, add arrows and write the sizes and notes next to them. Lekh turns your rough circles and arrows into clean shapes, so the marked-up photo is clear enough to send to a customer or a colleague.

How to mark up a photo in Lekh
1.Add the photo. Import a photo, a screenshot or a plan onto a board, or several photos side by side.
2.Draw on it. Circle, underline and point with arrows using your finger, a pen or a mouse. Lekh cleans up the shapes as you draw.

3.Write the details. Add text anywhere for sizes, notes and part numbers. Turn on scaling if you also want to sketch to scale beside the photo.
4.Share it. Export the board as a PDF or PNG, or share the cloud board with your team.
