Compression (Accusoft Cloud-Hosted Only)

The Compression API allows you to reduce the file size of a JPEG, PNG, or GIF image without any loss of visual quality. The expected results are a new version of the input image that looks exactly the same visually, but occupies less space.

Available URLs

URL	Description
POST /v1/imageReducers/{{filename}}?qualityFactor{quality}&removeMetadata={remove}&jpegMode={mode}	Reduces the size of an image. This is the preferred method.
POST /{{api-key}}/reduce/{{filename}}?qualityFactor={quality}&removeMetadata={remove}&jpegMode={mode}	Reduces the size of an image. This method is provided for backward-compatibility.

POST /v1/imageReducers/{{filename}}?qualityFactor{quality}&removeMetadata={remove}&jpegMode={mode}

Using this API, you can upload an image, reduce the image, and then receive the reduced image in response. The file contents are sent to the server in the body of the POST request.

URL Parameters

Parameter	Description
`{filename}`	(String) The name of file to reduce (not a file path).
`{quality}`	(Integer) JPEG files only. The desired quality of the output file. Acceptable values are: `0-255`, where `0` is the highest quality/least amount of compression, and `255` is the lowest quality/most compression. The default setting is `22`.
`{remove}`	(Boolean) JPEG files only. Specifies whether to remove metadata from the output file. A value of `true` will remove the metadata; a value of `false` (default) will preserve any metadata.
`{mode}`	(String) JPEG files only. Specifies the JPEG Mode of the output file. A value of `sequential` will convert the file to sequential mode; a value of `progressive` (default) will convert the file to progressive mode; a value of `preserve` will not change the current mode.
