remove.bg migration: what changes, and what to check before switching

An independent guide to the announced website, account and API changes, with official sources and a migration checklist.

These guides are available in English. Choosing another language opens that language’s help center.

This is an independent guide from remove.ac. It is not an official remove.bg notice, and it does not present remove.ac as an official successor, migration partner or endorsed provider.

remove.bg says its standalone website and accounts will become unavailable on December 1, 2026 at 09:00 CET. That is 08:00 UTC or 16:00 in Beijing. Its self-service API stops accepting requests from December 1; Enterprise API contracts continue. The API FAQ gives a date without specifying a time of day. remove.bg official FAQ

Start with the service you actually use

For people using the website, remove.bg directs background removal users to Canva. For self-service API users, it points to Leonardo.Ai. These are different paths; choosing a website replacement does not settle your API integration. remove.bg official FAQ

Check your balance and subscription separately. The FAQ says unused pay-as-you-go credits expire on December 1. Annual subscriptions receive an automatic proportional refund for unused time after the cutoff. Monthly subscriptions end automatically, with a final renewal on or after November 1 provided free. Before remove.bg account access ends, export your credit usage report and invoices from remove.bg. remove.bg official FAQ

An API migration needs more than a new destination

The Sync API path described in Leonardo's official migration guide requires a new API key and endpoint. Authentication changes to a Bearer token; requests and responses use JSON. Its documented output options do not include every remove.bg format. Read the mapping for the requests your application actually makes. These are Leonardo's requirements, not a claim about remove.ac compatibility. Leonardo official Sync migration guide

  1. List the inputs, parameters, output formats and batch sizes you use.
  2. Keep a representative set of images, including difficult edges and failed cases.
  3. Compare actual downloaded results, error handling, rate limits and charges.
  4. Change a small workflow first, with a fallback that will still be available when you need it.

Treat this as a preparation checklist, not a promise that any replacement will match your existing results.

Where remove.ac stands

remove.ac provides an on-device browser workspace for single-image and batch background removal. In on-device mode, the browser loads an approximately 78.2 MiB (82 MB) FP16 BiRefNet-Lite model via ONNX Runtime Web (WASM), predicts a 1024×1024 alpha matte, and applies a guided filter against your original image to export a full-resolution transparent PNG (up to 32 megapixels and 12,000 pixels per side). Manual Erase and Restore brush editing with Undo and Redo, solid or image background replacement, and PNG, JPG, WebP and batch ZIP exports run in the current browser tab.

First use downloads the model and browser runtime, so offline availability is not guaranteed. In on-device mode, selected image files are not uploaded to a server, and a local processing failure never switches to server processing automatically. Public API, Select subject, production authentication and paid plans are not enabled; local test-account screens are separate from production authentication.

For an existing plan or contract, use the provider's official policy and support channels.

Next step

Identify your website, account or API workflow, then review its current official documentation before making a production change. To test browser-only processing on your own image without uploading it to a server, open the on-device image editor or the local batch queue.
