I requested indexing through the Google search console. It's been 5-6 days, the article is still not indexed

Hi, you can use resizeimage.io They offer lossless compression of hi-res images. It's lifetime free.

You can use the Google Search Console’s URL Inspection Tool to request indexing. This can sometimes prompt Google to prioritize indexing the page.

Linking that article from other internal indexed pages will be helpful. Winning some quality backlinks for the article will ensure the ranking with indexing.
