How to Run a Reverse Face Search on a Phone

A phone can run a reverse face search in full: open FaceSearch in the mobile browser or the app, choose a photo from the camera roll or a screenshot, crop to the face, and search. The steps are the same on iPhone and Android; the differences are in how each handles photo formats and cropping.

In short

  • No desktop is needed. The whole procedure works from the camera roll.
  • Crop to the head and shoulders before searching, especially on a screenshot.
  • Screenshots of a playing video work, but pause first so the frame is not blurred.
  • iPhone photos may be HEIC; convert or screenshot them, since the search accepts JPEG, PNG and WebP.
  • Portrait mode blurs the background, not the face, so it is safe to search.

Can you run a reverse face search from a phone?

Yes, and nothing about the search is reduced on mobile. The same sources are searched and the same results are returned as on a desktop. FaceSearch runs in any mobile browser and also ships native apps for iPhone and Android, so a photo can go from the camera roll to a result without leaving the phone.

How do you search a photo that is already on your phone?

The camera roll is the usual starting point, and the only preparation that matters is making sure the intended face is the one being read.

  • Open FaceSearch in the browser or the app and choose the upload control.
  • Pick the photo from the camera roll, or take one now.
  • If more than one person is in the shot, crop to the head and shoulders of the person you mean before uploading.
  • Run the search and open each result at its source page rather than judging from the thumbnail.

How do you search a face from a screenshot?

A screenshot is often the only way to get an image out of an app that does not allow saving, and it works well as long as the capture is deliberate. Take the screenshot, then crop away the interface — the status bar, buttons and captions are not part of the face and only shrink the region the model gets. If the screenshot is of a video, pause it first: a frame captured mid-motion carries blur that the search cannot recover from.

Does the iPhone photo format matter?

It can. iPhones save photos as HEIC by default, and FaceSearch accepts JPEG, PNG and WebP. Most sharing paths convert automatically, so this rarely surfaces, but if an upload is rejected there are two reliable fixes: take a screenshot of the photo, which produces a PNG, or switch the camera to Most Compatible in Settings so new photos are saved as JPEG. Portrait mode needs no special handling — it blurs the background and leaves the face sharp.

Should you use the app or the mobile site?

Either. The apps and the site search the same index and return the same results, and an account carries its credits and history across all three. The apps are more convenient for repeated searches because the camera roll and the camera are one tap away; the mobile site is the faster choice for a photo someone has just sent you in a browser.

Why does a phone search sometimes return fewer matches?

Almost always because of what happened to the image before it was uploaded, not because of the phone. Every app that forwards a photo re-compresses it, and each pass removes detail the model needs.

  • A photo saved from a chat app has usually been compressed at least twice.
  • A screenshot of a photo inside another app is a copy of a copy.
  • Zooming in before screenshotting enlarges pixels without adding detail.
  • Where possible, get the original file rather than a forwarded version of it.
