The Bulk Toolkit

Background Removal

No signup required: this page gets a short-lived guest token for your browser, then uploads to the API. The server queues a job, runs the BiRefNet sidecar on each image, and stores a ZIP you download when the job finishes. Each result is a true transparent PNG (RGBA with an alpha channel — removed areas are see-through, not pasted onto white). Set BIREFNET_SERVICE_URL on the API and run toolkit-birefnet. Sign in later if you want a full account and premium quotas.

Up to 20 images per request (or a .zipof images — same as other bulk tools), up to 10 MB each on the API. Outputs are PNG with alpha (proper transparency for overlays and design tools). After upload, this page polls job status so the browser tab does not need one long hanging request while BiRefNet runs (often minutes per image on CPU).
