Apple has cracked down on apps that overtly claim to download YouTube video to your iPhone or iPad. However, it is still possible in iOS 9 and iOS 10. Our step-by-step guide will show you how to download YouTube videos to iOS.

YouTube promised to introduce offline watching, but this has only happened in the form of YouTube Red, which is an ad-free subscription service that's available only in the US at the moment.

Currently, you can use Documents 6 to download videos directly on your iPhone or iPad. This is available only in the UK App Store, and we're unaware of an equivalent for US users.

An alternative to the direct method is to use a PC or laptop and a free utility to download a video and transfer it straight to your device's Videos app with just one or two clicks.

We also explain explain whether it is legal to download YouTube videos. 

Documents 5

On your device, go to the App Store and search for "Documents 6". This is a free file management app that'll let you download YouTube videos. 

Once installed, launch Documents 6 and tap the bottom-right icon that looks like the Safari icon (a compass).

This will display a web browser where you can search for "savefromnet" (without the quotemarks).

Tap on the en.savefrom.net link in the search results.

Go to YouTube

You need to get the URL - the web address - of the YouTube video you want to download. One of the easiest ways is to launch the YouTube app on your iPhone.

Find the video you want and wait until any advert has finished playing and the video begins. Tap on the video to show the controls, then tap the share icon (an arrow pointing right).

Now tap Copy Link.

Return to the Documents 6 app, and tap in the white box to select it. Tap again to bring up the Paste option and tap that to paste in the URL you copied from the YouTube app.

Download video

Tap the green tick and you will see a list of various resolutions, so you can choose the quality you want. 

Tap the green Download link next to your preferred quality and rename the video if you want to. Now tap Done and the video will download. It's best to do this via Wi-Fi as videos can quickly use up your monthly data allowance.

Move video

Once downloaded, you'll see the video in the Downloads section of the Documents 6 app.

You can save this to your iPhone or iPad's Photos app (not the native Videos app, unfortunately). To do this, tap and hold on the video and drag it up until you see the folder list. Keep holding and drag it into Photos and then into Camera Roll.

Now you can just head to the Photos app and watch the video.

Download via PC

If you don't like the hassle of copying and pasting links and switching between apps then there's an easier way if you have a PC (or a Mac) using Softorino's YouTube Converter.

Head to the YouTube Converter website and download the version you want - Windows or Mac. The downside is that this app isn't free - it costs $19.99.

Connect your phone or tablet to your PC and tap the 'Trust' option if asked.

An alternative is YouTubeByClick which is free with an optional premium mode that gives you more control over the quality of the file you download. This won't transfer videos directly to your iPhone or iPad, so you'll have to do that via iTunes or other software.

Download & transfer

Now head to a web browser and copy the URL of a YouTube video you want to download. The video will automatically appear in the YouTube Converter program (and YouTubeByClick also works in the same way). You can copy more URLs and build up a list of videos to transfer to your iPhone or iPad.

You then need to choose the quality for the videos. Although you can select 4K, it's more sensible to choose 720p or 1080p as no iPhone or iPad yet has a 4K screen, and your chosen video may not even be 4K.

Click the Convert and Transfer to iPhone button and the videos will be downloaded and transferred to your iPhone's Videos app. It can take a while, so do this well in advance of needing the videos.
