Compress Images API

Hosted on ApyHub

What it does

The image compression API reduces the file size of raster images. Send a public image URL or upload the file (up to 100 MB per request), set compression_percentage from 1 to 100, and get the compressed image back as a file download or as a time-limited signed URL. It supports JPEG, PNG, WebP, GIF, TIFF and BMP.

Set preserve_format to true to keep the original format, and use output to name the result. The four endpoints cover each combination of input and output: URL in or file in, file back or link back.

Use the image compression API wherever image weight costs you something. Compress user uploads before they reach storage, shrink product photos for faster catalog and landing pages, reduce attachment size in email and chat workflows, and cut bandwidth for mobile apps on slow connections. A batch job over an existing media library can lower storage and CDN costs without re-shooting a single image.

Compression works best as one step in an image pipeline. Resize to the display dimensions first with the Image Resize API, then compress. For modern web formats, convert with the JPEG to WebP API. When compressed scans or receipts need to become a document, the Image to PDF API turns them into a PDF.

Query Parameter(s)

Attribute	Type	Mandatory	Description
output	String	No	Output file name.
preserve_format	Boolean	No	Defaults to `false`.
compression_percentage	Integer	Yes	Compression level as a percentage between `1` and `100`.

Request Body

Parameter	Type	Mandatory	Description
url	String	Yes	Publicly accessible URL of the raster image to compress. Supported formats: JPEG, PNG, WebP, GIF, TIFF, BMP. If the URL does not start with a recognised scheme (`http`, `https`, `ftp`, `sftp`), `https://` is prefixed automatically.

About this endpoint

What it does

Compresses an image fetched from a publicly accessible URL and returns a time-limited signed URL for the compressed file.

Query Parameter(s)

Attribute	Type	Mandatory	Description
output	String	No	Output filename base.
preserve_format	Boolean	No	Default: `false`.
compression_percentage	Integer	Yes	Compression level. Minimum: `1`, maximum: `100`.

Request Body

Parameter	Type	Mandatory	Description
url	String	Yes	Publicly accessible URL of the raster image to compress. Supported formats: JPEG, PNG, WebP, GIF, TIFF, BMP. Must be a URI. Hosts without a recognised scheme (`http`, `https`, `ftp`, `sftp`) receive an `https://` prefix automatically.

Response

Returns a JSON object with a data string field containing a time-limited pre-signed URL to the stored compressed image. The URL is always present on a 200 response and should be downloaded or forwarded before it expires.

Attribute	Type	Mandatory	Description
data	String	Yes	Time-limited pre-signed URL to the stored compressed image. Always present on a `200` response. Download or forward the file before the URL expires.

About this endpoint

What it does

Compresses an uploaded raster image and returns the compressed file as a binary download. You send the image in a multipart request body, along with query parameters that control the output name, whether to preserve the original format, and the compression percentage.

Query Parameter(s)

Attribute	Type	Mandatory	Description
output	String	No	Output filename/base name for the compressed file.
preserve_format	Boolean	No	Default: `false`. When `true`, preserves the original image format.
compression_percentage	Integer	Yes	Compression percentage from `1` to `100`.

Request Body

Parameter	Type	Mandatory	Description
image	Binary	Yes	Raster image file to compress. Supported formats: JPEG, PNG, WebP, GIF, TIFF, BMP. Format: binary file upload.

Response

Returns a binary file download containing the compressed image. The response schema is a string with binary format, so the success response body is the file content itself rather than a JSON object.
