A practical tool, a clearer next step

Compare Your Progress Photos

Align two photos in your browser. Compare side by side, with a slider, or as an overlay, then download a new PNG.

Your photos stay in this browser tab. Nothing is uploaded or saved by this tool.

Choose two photos, then match your position and scale. Use similar lighting, posture and camera distance for a fair comparison.

JPEG, PNG or WebP · up to 15 MB and 40 megapixels per photo.

Choose both photos to see your comparison.

A visual comparison is not a body-fat measurement. Alignment and lighting can change how progress looks.

How to interpret the result

Use JPEG, PNG or WebP photos up to 15 MB and 40 megapixels each. Adjust zoom and position separately. Images stay in this browser tool; it does not estimate body fat or send photos for AI analysis.
