Croppi: A Safari Extension for Easily Cropping Images


Croppi is a simple iOS Safari extension that allows users to easily take screenshots, crop them, and save them to either the clipboard, or a file that can be saved. I created it because I quickly became frustrated with how many steps it took to take a screenshot, crop the relevant section, and save it.

Not only that, but after the process, I'm left with hundreds of soon-to-be useless photos in Camera roll, taking up space.

Croppi in Action!

So, I created an extension that reduces the friction of taking and cropping screenshots, without having to actually store the images. Instead, Croppi can save cropped images directly to the clipboard!


As with most things in life, there are unfortunately some limitations that users should be aware of.

  • The free version places a watermark in the images. Purchasing the premium version (which can be done in the app) removes this watermark. Please support indie developers like me!
  • Invoking the extension while zoomed in makes it difficult to use. Fixed!
  • Invoking the extension while zoomed out makes the interface smaller. This affects sites that are, by default, zoomed out to fit your iphone's width, such as iOS's implementation of "browser.tabs.get/setZoom" is absolutely busted, so there's not much I can do about this.


The plugin works INSIDE the web page that you're viewing, so it needs permissions to read/access the page that you're on.

But rest assured: this plugin does not save, store, or transmit any webpage data to me, Apple, or any third party companies. All webpage and image data stays directly on your phone, where it belongs.

Closing Remarks

Overall, it was a little more time consuming than I expected (roughly 2 weeks' worth of my after-hours free time), but this was a fun little app to create. While some of iOS16's new features make this app somewhat obsolete (before iOS16, one could not take a screenshot and NOT save it to Camera Roll!), I still think that it's a nifty little extension that should save users some time and frustration when taking screenshots in Safari!

On one final note: Apple, please fix your Safari extension APIs!
