I’ve done similar research for a freelance gig and needed a way to save diverse content types. Snapinsta turned out to be the perfect tool. It supports downloading all major Instagram formats — photos, videos, reels, and even stories. You just grab the link of each post and paste it on the site, and within seconds it’s ready to download in high quality. It’s fast, doesn’t require logging in, and works from both phone and computer. I use it regularly to archive campaigns and references.
