Resize Image to Custom Dimensions API

What it does

Image Resize lets you send a PNG or JPEG and get back a resized image as binary output. You provide the source file plus target width and height, and you can optionally set format to png or jpeg if you want the output converted instead of keeping the input format.

Use it when you need consistent image dimensions for product galleries, profile uploads, email templates, or thumbnails. The endpoint accepts images up to 15 MB, so it fits common application workflows without adding an image processing stack to your own service.

The response is the resized image file itself, which makes it easy to store, pass to another service, or return directly from your backend. If you are normalising user-uploaded images or generating fixed-size assets for a web app, Image Resize gives you a simple transformation step with predictable inputs and outputs.
