Libraries
Get up and running faster with official and third-party libraries.
Not a developer? There are plenty ready to use Tools & Apps by remove.bg and our community.Output formats
You can request one of three formats via the format
parameter:
Format | Resolution | Pros and cons | Example |
---|---|---|---|
PNG |
Up to 10 Megapixels e.g. 4000x2500 |
+ Simple integration + Supports transparency - Large file size |
Download 7 MB |
JPG |
Up to 50 Megapixels e.g. 8000x62500 |
+ Simple Integration + Small file size - No transparency supported |
Download 1 MB |
ZIP |
Up to 50 Megapixels e.g. 8000x6250 |
+ Small file size + Supports transparency - Integration requires compositing |
Download 3 MB |
Please note that PNG images above 10 megapixels are not supported. If you require transparency for images of that size, use the ZIP format (see below). If you don't need transparency (e.g. white background), we recommend JPG.
How to use the ZIP format
The ZIP format has the best runtime performance for transparent images.
In comparison to PNG, the resulting file is up to 80% smaller (faster to download) and up to 40% faster to generate. For performance optimization we recommend using the ZIP format whenever possible. Above 10 megapixels, usage of the ZIP format is required for transparent results.
The ZIP file always contains the following files:
color.jpg | A non-transparent RGB image in JPG format containing the colors for each pixel. (Note: This image differs from the input image due to edge color corrections.) – Show example |
alpha.png | A non-transparent grayscale image in PNG format containing the alpha matte. White pixels are foreground regions, black is background. – Show example |
To compose the final image file:
- Extract the files from the ZIP
- Apply the alpha matte (alpha.png) to the color image (color.jpg).
- Save the result in a format of your choice (e.g. PNG)
Sample code for linux (requires zip and imagemagick):
$ unzip no-bg.zip && \
convert color.jpg alpha.png \
-compose CopyOpacity \
-composite no-bg.png
A zip2png
command is integrated in our command line interface. More code samples can be found here.
OAuth 2.0
If you want to authenticate users with the click of a button instead of having them enter an API Key, get in touch to try our OAuth 2.0 login.
API Reference
Rate Limit
You can process up to 500 images per minute through the API, depending on the input image resolution in megapixels.
Examples:
Input image | Megapixels | Effective Rate Limit |
---|---|---|
625 x 400 | 1 MP | 500 images per minute |
1200 x 800 | 1 MP | 500 images per minute |
1600 x 1200 | 2 MP | 500 / 2 = 250 images per minute |
2500 x 1600 | 4 MP | 500 / 4 = 125 images per minute |
4000 x 2500 | 10 MP | 500 / 10 = 50 images per minute |
6250 x 4000 | 25 MP | 500 / 25 = 20 images per minute |
8000 x 6250 | 50 MP | 500 / 50 = 10 images per minute |
Exceedance of rate limits leads to a HTTP status 429 response (no credits charged). Clients can use the following response headers to gracefully handle rate limits:
Response header | Sample value | Description |
---|---|---|
X-RateLimit-Limit
|
500
|
Total rate limit in megapixel images |
X-RateLimit-Remaining
|
499
|
Remaining rate limit for this minute |
X-RateLimit-Reset
|
1728622268
|
Unix timestamp when rate limit will reset |
Retry-After
|
59
|
Seconds until rate limit will reset (only present if rate limit exceeded) |
Higher rate limits are only available to high-volume solution users; get in touch here.
Exponential backoff
Exponential backoff is an error handling strategy in which a client periodically retries a failed request.
The delay increases between requests and often includes jitter (randomized delay) to avoid collisions when using concurrent clients.
Clients should use exponential backoff whenever they receive HTTP status codes 5XX
or 429
.
The following pseudo code shows one way to implement exponential backoff:
retry = true
retries = 0
WHILE (retry == TRUE) AND (retries < MAX_RETRIES)
wait_for_seconds (2^retries + random_number)
result = get_result
IF result == SUCCESS
retry = FALSE
ELSE IF result == ERROR
retry = TRUE
ELSE IF result == THROTTLED
retry = TRUE
END
retries = retries +1
END
