Instant approximate dimensions in mm, cm, inches, or feet. Share or export the annotated image.

AI Tools

When the photo isn't perfect,
AI fills the gap.

Photo cut off at the edges? AI continues the scene naturally — keeping the right scale for measuring.

Paint over distractions. AI removes them and fills the area seamlessly so your measurement stays clean.
