How to Add Chapters to YouTube Videos (and Why They Don't Show)
Add chapters to a YouTube video with timestamps in the description. The four rules chapters must follow, automatic chapters, and fixes when they don't appear.
Step-by-step: save any YouTube or Shorts thumbnail to your phone's gallery on iPhone (Safari) or Android (Chrome) — no app needed.
You don’t need an app to save a YouTube thumbnail on your phone. Your browser can do it in under a minute.
https://youtu.be/ or https://youtube.com/shorts/.If Safari saved the thumbnail to Files → Downloads, open it there, tap the Share icon and choose Save Image. It now appears in Photos, ready for Instagram, CapCut or any editing app. To skip this step next time, use the long-press → Save to Photos method instead of the Download button.
Tap the ⋮ menu in Chrome and choose Downloads: every file you saved is listed there, newest first. Gallery and Google Photos usually show downloads in a Download album; if an image is missing there, open the Files app and look in the Download folder.
A Short’s link (youtube.com/shorts/…) works the same way. Keep in mind that YouTube stores most Shorts thumbnails as a landscape image with bars at the sides, so for a full-screen vertical picture use the Shorts thumbnail downloader, which shows what each size looks like.
Saving thumbnails for a whole playlist or a list of links one by one is slow. Paste all the links into the video ID extractor: it gives every video’s HD thumbnail link, so you only tap and save.
A thumbnail belongs to the creator who made it. Saving it for reference, a review or a reaction is common; uploading it as your own thumbnail is not. Read can I use someone else’s YouTube thumbnail? before you publish it anywhere.
No. Everything works in your phone's normal browser. Be careful with thumbnail "apps" that ask for extra permissions — they aren't needed.
On iPhone it goes to Photos (if you chose Save to Photos) or the Files app → Downloads. On Android it goes to the Downloads folder and appears in Google Photos / Gallery.
Yes. Paste all the links into the video ID extractor; it lists every video with a direct HD thumbnail link, so you can open and save them one after another without going back to YouTube.
You probably saved a small size such as Medium or Default. Choose HD (1280 × 720) or SD (640 × 480). If HD is not available, the video was never uploaded in HD and SD is the sharpest version that exists.
Paste a link and download every available size, up to 1280×720.
