Bulk Edge Detection Free

Runs 100% in your browser — your files never leave your device.

Turn a folder of photos into sketch outlines, isolate shapes across many images, or preview edges for a whole set at once. A Sobel operator is applied to every file, and all the detection runs locally in your browser.

How it works

    Drop one or more JPG, PNG, or WebP files into the box. Nothing is uploaded.

  2. 2

    Detect edges the batch

    Set the control once — it is applied to every file in the batch.

  3. 3

    Download the results

    Process the batch, then download each edited image individually.
