How to Save YouTube MP4 Videos to iPhone

iPhones don't make this obvious — there's no download button in the YouTube app, and Apple blocks most downloader apps from the App Store. But Safari plus a web downloader gets it done with no jailbreak.

Follow these steps exactly and the video lands in your Files app, ready to watch offline or move to Photos.

iPhone owners get the worst deal from downloader apps — Apple bans them, so the App Store is a dead end. The Safari + web downloader method is the workaround Apple can't block, because it's just a website doing what websites do. xi is optimized for this flow: paste, download, save to Files, done. No profiles to install, no enterprise certificates to trust.

How to do it — step by step

Step 1. In the YouTube app, tap Share under the video, then Copy link.

Step 2. Open Safari and go to apiproai.com. Paste the link into the input box and tap Download.

Step 3. Choose MP4 and your preferred quality, then tap the download link.

Step 4. When Safari asks, choose Download. Then tap the downloads icon, tap the file, and choose Save to Files.

Step 5. Open the Files app — your video is there. To put it in Photos, open the video in Files, tap Share, then Save Video.

Tips

Use Wi-Fi: iPhone downloads over cellular can be slow and eat your data plan.
If Safari blocks the download, check Settings → Safari → Downloads is set to ask or to Files.
MP3 is better than MP4 for music — smaller files, and they play in the background.
iOS may not preview some formats in Files — but Save Video to Photos always works for MP4.

Common mistakes to avoid

Trying to download inside the YouTube app — iOS doesn't allow it; use Safari instead.
Looking for the file in Photos immediately — it goes to the Files app first, then you move it to Photos.
Downloading over cellular — iPhone downloads can be slow and data-hungry; use Wi-Fi.
Installing a 'downloader app' from outside the App Store — sideloading profiles is a security risk; Safari is enough.
Giving up when Safari shows a preview instead of downloading — long-press the link and choose Download Linked File.

Frequently asked questions

Do I need to jailbreak my iPhone?

No. This method uses only Safari and the Files app — no jailbreak, no sideloading, no shady profiles.

Why isn't there a YouTube downloader app on the App Store?

Apple's App Store rules prohibit YouTube downloading apps. Web-based tools like xi sidestep this entirely.

Where exactly is my downloaded video?

In the Files app, under Downloads or wherever you chose. From there you can move it to Photos.

Can I download directly to the Photos app?

iOS requires the Files detour, but it's two extra taps: Files → Share → Save Video. Done.

Does this work on iPad too?

Yes — identical steps in Safari on iPad.

After saving to iPhone

Move the video from Files to Photos (Share → Save Video) for easy viewing.
Free up space: delete the Files copy once it's in Photos to avoid duplicates.
For music, prefer MP3 downloads — they play in the background and use less battery.
Back up important videos to iCloud so a lost phone isn't a lost library.
