BG0 vs Removal.AI

BG0 is a free web tool that removes image backgrounds in the browser and downloads transparent PNG files. Image bytes remain in the browser rather than being uploaded for processing. The remover accepts PNG, JPG, WebP, HEIC, and HEIF images up to 40 MB. It runs BiRefNet and can fall back to BiRefNet-lite when the selected model cannot run. First use requires an internet connection to download and prepare the model, after which the browser may cache it. There is no account, credit system, subscription, or stated usage limit. Developers can use the @bg0/browser library to add on-device removal to web apps without a server or API key; it runs through WebGPU or WebAssembly. The documented iOS path uses a single-threaded WebAssembly worker and BiRefNet-lite, with output limited to 1280 pixels on the longest edge. No manual touch-up editor is included. BG0 uses PostHog for anonymous analytics.

Removal.AI removes image backgrounds and can produce white, custom, or transparent backgrounds in three seconds or less. The web editor can replace backgrounds, add text and effects, and let users manually edit the foreground with a background eraser. Bulk Upload accepts up to 100 images per upload and uses half the credits per image; the service also describes processing over 1,000 images in one upload. A desktop app for macOS and Windows supports whole-folder processing, background colors, pause and resume, ecommerce optimization, and automatic cropping. The API takes direct uploads or image URLs and returns a file URL or Base64 output, with resolutions up to 25 megapixels. New API users receive 10 free preview credits per month by default, and a Figma plugin is available. The Free plan costs nothing and is limited to 0.25 megapixels and personal use. Paid options include credit packs billed once and monthly plans; the three-credit lifetime option is listed at $1.89 a month, billed once. JPG or PNG uploads can be up to 12 MB, and images above 36 megapixels are resized.
