Image I/O
Input
Our API supports several options to provide source images that need to be processed.
HTTP(S) URL
URL of the input image should be from 1 to 512 characters. The image must be accessible by our system.
Image upload
Our API also supports the ability to upload image content directly. Just make sure that all respective headers are set. See Upload API Reference for more info.
Connected storage
You can connect Cloud Storage and use it as a source for images. Currently, our API supports AWS S3 and Google Cloud Storage.
After connecting your Cloud Storage, you can refer the storage name as an input.
Input image file types
Our API supports the following image formats as inputs: BMP, GIF, JPEG, PNG, TIFF, WEBP, AVIF, and HEIC.
Output
Configuration of result output is optional.
By default, you may omit the output option from the request payload. In this case, our system stores the result in a temporary bucket with a lifespan of 24 hours and provides a public URL to the image.
Alternatively, you can use a connected Cloud Storage: just configure the path to the folder where you want to store results.
Output image file types
The following image formats are supported for the output: JPEG, PNG, WEBP, and AVIF.
Basic and advanced output options
See the full list of the advanced format-specific options below:
Name | Type | Description |
---|---|---|
| integer | Specifies the amount of JPEG lossy compression in the range 1 - 100. Defaults to 85. |
| boolean | Progressive JPEG loads in a browser in successive waves until a clear picture is formed, thus improving the image loading speed. Used by default. |
Color space
Name | Type | Description |
---|---|---|
| string | Is the color space for digital images. Use the RGB color mode if your image is supposed to be displayed on any kind of screen. |
