Let’s say we don’t want to just resize, but we want to crop too. If for some reason you want to distort the image, you can do that too by adding the fit:scale parameter. We’ll assume that most people don’t want to distort their images when resizing, so even given resize=width:200,height:200, Filestack resizes to 134×200 to preserve the aspect ratio. We can also set a height dimension resize=width:200,height:200 Notice the image is smaller now, but the aspect ratio is preserved even though we only specified one dimension. Let’s start by resizing to a width of 200px by adding resize=width:200 to our base url. my S3 object url or in this case, Wikipedia Url), add the Filestack transformation API endpoint, an API key and the conversion parameter. We’ll just take the image URL that we want to transform (e.g. No installing and configuring ImageMagick. In order to resize, fit and align this image however we want, all we’re am going to do is append some simple parameters to the URL. Let’s start with an image like the one below.

All the examples with use images stored on s3, but all the examples will work with any image stored on any internet-accessible storage. In today’s post, we’ll show you how to automatically resize, fit, and align any image stored on an object store like AWS s3, Azure Blob Storage, or Google Cloud storage. ImageMagick is another solution that will allow you to truly crop the image to size, but at over 11,000 words just for the docs on cropping, ImageMagick is complicated, to say the least and overkill for most tasks (full disclosure, we use ImageMagick and use some of its options in our own backend, but we have a team of 20+ developers building Filestack and you probably don’t). Photoshop “just works” but a) it’s a really expensive way to just crop an image and b) do I seriously have to wait 37 seconds for it to initialize just to open an image? ImageMagick is probably overkill Resizing with Photoshop works but its slow If this is an ecommerce site, then suddenly your site is going to slow down way more than necessary and your users, especially on mobile, are going to go somewhere else.
