Overview

What this guide covers

Conversion path

Use Converterer to accept or prepare a GIF file, trigger a GIF to ICO job, and return the output to your app or workflow.

PHP example

Start with the example on this page, then adapt auth, file handling, polling, and result delivery to your environment.

Production usage

This is best suited to backend jobs, async processing, content pipelines, and repeatable conversion flows rather than one-off browser scripting.
