How to recreate your long-lost Pinterest bookmarklet.

Right-click your bookmarks bar and choose Add Page (Chrome) or New Bookmarklet (Firefox).

In Name, put this:

Pin It

In URL, put this:

javascript:void((function(d){d.addEventListener('securitypolicyviolation',function(r){alert('ContentSecurityPolicyError!');});e=d.createElement('script');e.setAttribute('type','text/javascript');e.setAttribute('charset','UTF-8');e.setAttribute('debug','true');e.setAttribute('src','//assets.pinterest.com/js/pinmarklet.js?r='+(Math.random()*99999999));d.body.appendChild(e);}(document)));

For My Little Friend Safari:

• open about:blank in a new window (this will help you not have to mess around with favicons later)
• hit command-D
• choose Favorites under Add this page to:
• enter Pin It in the Name box
• right-click the Pin It bookmarklet you just made and choose Edit Address
• paste in the JavaScript from above

If You're Running Chrome or Firefox, Pinmarklet will Bother You to Install the Pinterest Browser Extension

• From time to time you'll see a big banner in the image grid, begging you to please install the extension.
• If you don't want to install the extension, click the "no, thanks" button to set a two-week cookie.

Why you Might Want the Extension After All

• Pinning with the extension is much better, especially if you pin a lot. You'll have free hovering Save buttons (which you can turn off in Settings) and you can right-click and pin an image without the intervening wait-for-the-grid / pick-an-image cycle.
• Pinning happens right there inline instead of in a pop-up window.
• You also get Visual Search for free. Right-click the body of the page to search a full screenshot, or choose the hovering selector button to search an individual image.

For those seeing the ContentSecurityPolicy error, that's probably happening because you're running pinmarklet on GitHub, which forbids external JavaScript embeds.

Thank goodness it still works on Safari.

I don't understand why there's no pinterest safari extension.

I can't comment on why there is currently no Safari extension, but I can talk about why there wasn't one at the time I left Pinterest.

As was true for Chrome and Firefox there was a version 1 extension for Safari, which did nothing but inject pinmarklet.js. That extension quit working along with many others when Apple shipped Safari 12, which instituted a whole new "App Extension" framework. App Extensions were incompatible with the WebExtensions API, which allowed Pinterest to use a single codebase to ship version 2 (and all subsequent versions) to Firefox, Chrome, and (later) Microsoft Edge.

Later on at WWDC20 Apple announced Safari Web Extensions, which came with a utility that was supposed to convert extensions built on WebExtensions. Unfortunately this utility did not work for the Pinterest extension, and management decreed that the team--which consisted of me--was to work on shipping features and not a Safari extension.

I'm not 100% sure what's happening with the Pinterest extension; as of 2024-02-04 there's a new version for Chrome that seems to have had all features except saving to Pinterest stripped away. It's possible that this smaller version might survive conversion to Safari but I can't say for sure, since it's an obfuscated bundle of React droppings. :(

Ahh, thank you so much for this simple solution. I'm still a user of the Pin It button, but I needed to add it in a different chrome profile. The last time I used the extension, I couldn't stand the Save buttons plastered all over the images on every website or having to turn them on and off when I wanted to pin something, if I remember correctly. It's been a while since I tried it, but I went back to the Pin It button and it satisfies my needs better than the extension.

Works great in Safari v17. Can only select one photo to pin each time you run the script, but it's a great workaround until Pinterest gets over their Apple antipathy and releases a native extension. (or until Apple decides to become more developer-friendly 🙄 hah!)

Working in 2026! Thanks so much for this. I have it on my Apple Mac desktop and wanted to install it on my Apple, but couldn't remember how to install it. I came across your helpful post on GitHub and completed it in no time. I find it a great backup, as some pages don't allow you to pin (the Pinterest button doesn't appear), but this simple little marklet seems to get the job done.
