Use when Codex needs to cut out a subject from a local image file or image URL, produce a transparent PNG or WebP, export a flat JPG, or verify remove.bg account access before running image background removal.

Remove Image Background

Use this skill to remove the background from a single image through the remove.bg API.

Setup

Store the API key on this machine before the first real run:

/Users/rileybrown/.codex/skills/remove-image-background/scripts/remove_bg.py setup --key "<REMOVE_BG_API_KEY>"

Check configuration and account access:

/Users/rileybrown/.codex/skills/remove-image-background/scripts/remove_bg.py config:show
/Users/rileybrown/.codex/skills/remove-image-background/scripts/remove_bg.py account:get

Notes:

setup stores the key in the macOS Keychain by default.
REMOVE_BG_API_KEY or REMOVEBG_API_KEY overrides stored config for one-off runs.
Use --location global only when a plain config file is explicitly preferred over Keychain storage.

Quick Start

Remove the background from a local image and save a sibling output automatically:

/Users/rileybrown/.codex/skills/remove-image-background/scripts/remove_bg.py remove /absolute/path/to/image.jpg

Remove the background from an image URL and write to an explicit output path:

/Users/rileybrown/.codex/skills/remove-image-background/scripts/remove_bg.py remove "https://example.com/image.jpg" --output /tmp/image-no-bg.png

Common Options

--output <path>: choose the output path. When omitted, local files become <name>.no-bg.<ext> beside the input file, and URLs save into the current directory with a sanitized filename.
--format png|webp|jpg|zip: choose the output format. Default is the --output file extension when you provide one, otherwise webp for higher-resolution transparent output.
--size <value>: pass the remove.bg size parameter. Default 50MP.
--type <value>: pass a foreground hint such as person, product, car, graphic, animal, or transportation.
--crop: ask remove.bg to crop empty margins.
--bg-color <hex>: flatten the output onto a solid background color instead of transparency.
--max-retries <n>: retry 429 responses by honoring Retry-After. Default 2.

Workflow

Run config:show if background removal has not been configured on this machine yet.
Run account:get when you want to verify the key without spending a removal call.
Use remove with a local path when the user gives you an attached image or a file on disk.
Use remove with a URL when the image already lives on the web and downloading it first adds no value.
The default path favors maximum quality: size=50MP plus webp when no output extension forces another format.
Prefer png only when downstream tooling specifically requires PNG. Use jpg only when transparency is not needed.

Output

Successful runs write the processed file locally and print JSON with the output path plus useful response headers such as credits charged and detected foreground type.
Failed runs exit non-zero and include the HTTP status plus the response body excerpt.
