Remove the background from product photos, in a batch

Cut out catalog photos locally. Crop, cap the long edge, compare before and after, and download a ZIP of transparent PNGs.

Catalog photos are repetitive. The same table, the same sweep of paper, a different object in the middle. LocalBG treats that as a batch: drop the folder’s worth of JPG, PNG, and WebP files, and each one is cut out on its own. They do not share a canvas, and a failure on one file does not discard the others. When a row says it is ready, its PNG button is live. Download ZIP packs every finished PNG.

Crop and size before the model runs

A product frame often includes a stand, a tag, or a second object you do not want. Drag a rectangle on the preview, or type the crop as percentages. The same relative rectangle is applied to every file in the batch, which is what you want when the camera did not move. Reset it if the set is mixed.

The resize control is the long edge of the file you download. 2048 is the default. 1280 is enough for a grid thumbnail. “Original” still stops at 4096 so a 40 megapixel RAW export converted to JPG does not exhaust the tab. The model does not see that full raster. It sees a 512×512 normalized view, then the matte is scaled back with a bilinear filter. For a hard-edged product on a clean backdrop this is sharp enough. Fine mesh and motion blur remain the hard cases for any automatic matte.

Check the edge before you ship the file

Use the before/after slider on the finished row. Look at handles, glass, and anything the same color as the table. If the matte ate a highlight, crop tighter so the object fills more of the 512 view and run that file again. The free background remover guide covers the output formats. Nothing in this flow posts the catalog to a server.
