Send raw file bytes#

The Binary body type sends the raw bytes of a file as the request body. Use it to upload an image, a document, or any file that goes out unchanged rather than wrapped in a form. You select a file on disk, and the app sends its bytes when you send the request.

Select a file#

Switch the body type to Binary and select Choose file. A file picker opens for you to select one file. The panel then shows the file name, a button to select a different file, and a bin icon to clear it.

The request holds the file path, not a copy of the contents. The app reads the bytes from disk at send time, so the file goes out as it stands when you send. Large files stay out of the way until then.

The Content-Type it sets#

A binary body goes out as application/octet-stream. To send a different type, add a Content-Type header on the Headers tab, such as image/png. The app then uses your value.

Choose between Binary and form-data#

Use Binary when the body is the file itself. Use form-data when the file is one field among several, or when the endpoint expects a multipart upload.
