The extractor recognises 5 distinct Unsplash URL shapes, which is why the link already sitting in your address bar normally works without you hunting for a share button. Whatever it resolves to comes back with its container intact. Everything from Unsplash goes through the gallery route, which enumerates a post's files instead of negotiating a stream. Some Unsplash URLs name a collection rather than a single item, and those return everything the collection holds. No credentials are involved anywhere in this path — neither yours nor ours.
Shortcut — stick tikt.com/ on the front of the Unsplash address instead of copying it here:
tikt.com/https://www.example.com/path/to/media
The whole process
1. Open the Unsplash post
Find the Unsplash post, album or profile page holding what you want and copy its address. A post URL gets you that post; a profile URL gets you what the profile has published.
2. Paste it above
Drop the URL into the field at the top of this page. The gallery extractor enumerates the files attached to that Unsplash page rather than guessing at one.
3. Take the files
Each file is listed at the size it was uploaded to Unsplash. Save one, or save the lot — nothing has been resampled or re-encoded in between.
