What this site doesn't do
It doesn't download videos or audio, from YouTube, TikTok, Instagram, Snapchat or anywhere else. Platforms' terms don't allow it unless they offer a download button themselves, the videos belong to the people who made them, and download tools break every time a platform changes. If you need your own video back, YouTube Studio and the TikTok app let you download your own uploads.
It doesn't log in to your accounts or scrape private posts. The link tools only read what a platform makes public for embedding, which is why Instagram, Snapchat, X and Twitch posts can't be grabbed here. The caption, hashtag and image tools work for all of them.
Want to reuse a thumbnail or a profile picture? Read Can I use someone's thumbnail? first.
