remove.bg stops accepting self-serve API requests on 2026-12-01. PixMiller mirrors its main path at
POST /v1.0/removebg — same X-Api-Key header, same parameter names, HTTP 200 with the image bytes in the body. A matching GET /v1.0/account returns your credit balance.

| remove.bg value | PixMiller tier | 설명 |
|---|---|---|
preview / small / regular
|
preview | Watermarked preview, up to 640 px. Free — no credit charged. This is the default, as on remove.bg. |
medium / hd / 4k / full / 50MP
|
full | Full-resolution, watermark-free result, downscaled to the tier's megapixel cap (1.5 / 4 / 25 / 25 / 50 MP; PNG output is capped at 10 MP). 1 credit per image. |
auto
|
auto | Full resolution when credits are available, free watermarked preview otherwise. |
X-Credits-Charged
Credits actually deducted by this call (0 for the free preview tier).
X-Width / X-Height
Pixel dimensions of the returned image.
X-Type
Detected foreground class: person, product, animal, car or other (omitted with type_level=none).
X-Foreground-Top / -Left / -Width / -Height
Bounding box of the subject in the returned image.
X-RateLimit-Limit / -Remaining / -Reset
Rate limit state for your key, counted per image — one call uses one unit; Retry-After is added on 429.
Every remove.bg parameter is accepted and validated — size, type, type_level, format, roi, crop, crop_margin, scale, position, channels, bg_color, bg_image_url and bg_image_file behave as documented by remove.bg. These are accepted but never change the output, as on remove.bg for non-car subjects:
shadow_type, shadow_opacity, add_shadow, semitransparency
- size=preview (and its aliases small / regular — the default, as on remove.bg) returns our free, watermarked preview at up to 640 px and costs no credit; remove.bg returns a 0.25-megapixel image without watermark for 0.25 credits.
- medium, hd, 4k, full and 50MP all cost 1 credit, as on remove.bg. There is no free monthly preview quota, so /v1.0/account always reports free_calls = 0.
- X-Type is a coarse class (person / product / animal / car / other) derived from the segmentation model that was used; type_level = 2 and latest return the same coarse classes.
- Shadows (shadow_type / shadow_opacity / add_shadow) and car-window semitransparency are accepted but never rendered — as on remove.bg for non-car subjects.
- Input files are limited to 20 MB (remove.bg: 22 MB).
Errors on this endpoint use the remove.bg JSON:API envelope {"errors":[{"title":"…","code":"…"}]}
with 400 invalid_parameter / 402 insufficient_credits / 403 auth_failed / 429 rate_limit_exceeded.
This is a compatibility layer for the main HTTP path, not a certified drop-in for the official SDKs or CLI.
