Why choose Knockout
Background removal in your browser.
Knockout is a free option for removing backgrounds without uploading a photo. Use it for an individual cutout, a small queue of photos or a social thumbnail. If you are comparing it with remove.bg or another editor, start with the workflow you need.
Why creators switch
Make a transparent PNG or prepare a product shot without creating an account. Your browser supplies the processing power, so speed and image limits depend on your device.

Do we reduce image quality?
The model works on a smaller copy, and exports apply its mask to the original within device limits. Inspect hair, glass and fine details. A transparent PNG preserves the resulting pixels without JPEG compression; it cannot restore detail the model missed.
If you used the remove.bg API
Knockout does not provide a hosted API. For automated catalog processing, compare the current API, pricing, quality and privacy terms of other services. Their availability and terms can change; consult their official documentation.
After the cut
The social thumbnail maker is a separate tool for YouTube, Instagram Reel, LinkedIn, or X. Drop your own photos there. If you already have a cutout, you can optionally bring it. Still on this device.
