How to count people in a photo and get a headcount you can check

This AI people counter estimates how many people appear in a photo and marks each one, so you can verify the headcount against the picture. Upload a group, class, event or crowd photo, choose Count people, and review the numbered boxes or the dots and heatmap. It works as a crowd counter for one wide shot and as a photo counter for a small group, on a phone or a computer. The estimate still needs your review.

Count people in image uploads, photos and pictures

To see how many people are in this photo, upload the widest, highest-angle frame you have, because a higher-up, wider shot captures more of the group than a close one. Small groups are detected person by person with numbered boxes you can check one at a time, while packed scenes switch to crowd-density counting with dots and a heatmap that shows where people are concentrated. The marked image carries the total, so you can count the people again yourself against the same picture.

  1. Upload a group or crowd photo, or select Take a photo on a phone.
  2. Leave the options at their defaults so the tool picks person-by-person or crowd-density counting.
  3. Choose Count people and wait for the markers.
  4. Check the total against the photo, then download the marked image.

Use the AI crowd counter for events and gatherings

As a crowd counter from image uploads, it needs one wide photo taken from a raised position, with as much of the gathering as possible in frame. Crowd counting from photo uploads, and crowd counting online from a single image, gives an estimate of attendance, not an official figure: overlap hides some people, so treat the number as a range and cross-check it with a second photo or another method. Max accuracy (slower) combines results from several engines when they are available. Herds and flocks have a livestock counter with tips for photographing from a higher vantage point.

Include people facing away or in profile

Face-first counting can miss people turned away from the camera. Turn on Include people facing away to search for people in profile, from behind or with a hidden face as well, which suits queues, audiences and group photos taken from the back of a room. Partial bodies and overlap can still cause misses or duplicate markers, so check the result before you trust it.

Tune the count and check every marker

Detection sensitivity runs from Strict to Lenient: raise it toward Lenient if people are missed in a small group, and lower it if a scene is over-counted. Included markers shows more or only the strongest detections, and Overlay style switches between dots, a heatmap, both or none. These display controls change only the preview, so reset them before you download. A second pair of eyes on the markers is the real accuracy check.

Count people in several photos and keep a record

Bulk audit, a Premium option, counts a queue of photos with the same settings and shows each photo count as a headcount, plus a grand total on screen, with a link to each marked image. People counting has no tally sheet, so download each marked image to keep a record, or sign in and save the reviewed count in the History tab, which can export saved counts as CSV. Blur faces with automatic face detection before you share a photo of a crowd. For anything that is not a person, count objects with your own examples.

Before you count a crowd

  • Shoot from a raised spot so heads are not hidden behind the ones in front.
  • Keep the whole group inside the frame, because people cut off at the edge are easy to miss.
  • Use the sharpest copy you have, since tiny, blurred faces are easy to miss.
  • Treat the total as an estimate and compare it with a second count when the number matters.

Before you share the marked photo, blur faces with automatic face detection, and for anything that is not a person, count objects with your own examples. Herds and flocks are counted on a livestock page meant for photos taken from higher up.

Max accuracy (slower)On / Off
Runs every counting engine on the photo and cross-checks their results for the most dependable headcount, taking a little longer to process.
Detection sensitivitySliderRange: 0–1 · Default: 0.5
Controls how eagerly people are marked, from Strict to Lenient — raise it if people in small groups are missed, lower it if things that are not people get counted.
