I have been working on a JavaScript project that retrieves original quality media from public Instagram post URLs directly in the browser without any backend server dependency. The concept is similar to how snapinstaink works as a browser based tool where a public post URL is parsed to extract the direct media file URL and then downloaded as a blob through the Fetch API. My current implementation uses fetch to request the public post page, parses the response text to locate the highest resolution media node, and then triggers a blob download in the browser. The main challenge I am running into is handling CORS restrictions when fetching the Instagram page directly from client side JavaScript without a proxy. Has anyone implemented a similar browser based media retrieval project in JavaScript and found a clean way to handle the CORS issue without introducing a full backend server.
Paraphrased you’d like to find a way to work around CORS. I’m sure there’s a reason the website has CORS and going around it (if indeed at all possible) will probably a violation of their TOS. Therefore, we can’t help you.
