EraseBG vs unbagrnd

EraseBG removes image backgrounds in a browser on the user’s device, with no usage limits listed for its free plan. It accepts JPG, PNG, WebP, and HEIC images, including batches, and provides erase and restore brushes, undo and redo, background choices, and before-and-after comparison. Optional 2× and 4× upscaling runs on the device. Exports are full-resolution PNG, WebP, or JPG, and batches can be downloaded as a ZIP. Processing uses the device’s GPU or CPU; the browser uses GPU processing automatically when WebGPU is supported. The maker says images remain in tab memory and are not collected, stored, or transmitted. The model can be cached for later offline visits. The source is MIT licensed and can be copied to a web server for self-hosting. It is available on web, iOS, Android, and as self-hosted software. Safari exports above about 16 megapixels are scaled to that limit, and iOS may reduce large photos during processing before full-resolution export. There is no API.

unbagrnd removes photo backgrounds with on-device AI, and its desktop app processes images locally through ONNX Runtime. The maker says images, filenames, and metadata are not sent anywhere; the app makes a one-time model download and has no analytics, update checks, or telemetry. Users can choose among several models with different speed and accuracy tradeoffs; the default is described as 43 MB. Editing tools include brush erase and restore with undo and redo, edge shift and smoothing, background color and shadow styling, and alpha matte export. It is intended for single photos or folders, including cutout refinement and background styling. A Docker-based REST API can be self-hosted to process images inside the user’s container. Its documented defaults include a 20 MB image limit, dimensions up to 8192 pixels, batches of up to 10, and 60 requests per API key per minute. The API uses plain HTTP, so a reverse proxy is recommended for TLS when exposing it publicly. The software is free and MIT-licensed, with Android, Linux, macOS, Windows, API, and self-hosted platforms listed.
