When using internet on your iPhone or iPad you may have noticed that some websites do not allow you to zoom in. This is a weird restriction several websites put on, which causes inconvenience for the users. So if you have a bad vision or want to properly view an images by zooming in you simply can’t. Luckily though someone has found a simple workaround to this issue enabling iOS Safari users to perform two finger pinch to zoom on any webpage of their choice.
All you have to do is follow a set of simple steps as shown in the video above. You will need the JavaScript code during the process which you can found below.
javascript:document.querySelector('meta%5Bname=viewport%5D').setAttribute('content','width=device-width,initial-scale=1.0,maximum-scale=10.0,user-scalable=1');
What you are doing here is you are creating a new bookmark and replacing its URL with the code above. Then whenever you find a page that restricts zooming you just have to go to the bookmarks menu and tap on the hacked JavaScript bookmark.
