Hyde Park - How well did Instagram downloads work without installing apps?

I prefer not installing a separate app for something I only do occasionally. A browser tool feels lighter because I can use it when needed and then simply close the tab. That also keeps my phone and laptop cleaner. For public Instagram photos, videos, and Reels, how well did downloads work for you without installing anything extra?

No-install tools are ideal for me when the task is occasional and simple. I like knowing that I can use the downloader from a browser without changing anything on the device itself. That keeps the process portable too, because I can repeat the same method on another computer or phone. If the site works well in the browser, I do not really miss having a dedicated app.
