Uploadcare is a hassle-free file infrastructure. We cover every aspect of your file handling. This section walks you through our workflow and features.
First, you can upload files right in a browser on any device. Your local storage, social media or a cloud can be a source for those uploads. That is done with Uploadcare Widget. What you get by default is a button,
You can add the widget to a page with just three lines of code,
<!-- The best place for this is your <HEAD> tag --> <script>UPLOADCARE_PUBLIC_KEY = "demopublickey";</script> <script src="https://ucarecdn.com/libs/widget/3.x/uploadcare.full.min.js" charset="utf-8"></script> <!-- And this is how you set the place on a page where the widget will appear. Do not miss the name attribute --> <input type="hidden" role="uploadcare-uploader" name="my_file" />
Uploadcare Widget works as a simple form element and lets you upload any file types including images, videos, PDFs, and other documents. We support files of up to 5TB in size and ensure their reliable and fast uploading with our distributed uploads network.
There are other install methods like NPM or Bower.
You have probably noticed
UPLOADCARE_PUBLIC_KEY was set to
The public key points to an Uploadcare project your uploads go to.
demopublickey to a
public_key of any project in your
Uploadcare account account to route the widget uploads there.
Our demo account would still accept your uploads, but keep in mind we clear its
storage every 24 hours.
And that is where we get to the next concept, Storage.
You do not have to store any of the uploaded files on your servers. All uploads go to our storage, and you receive unique file identifiers or UUIDs. You can store those in your database, textfile or even Moleskine.
This is how UUIDs look like,
Uploadcare features a smart CDN that powers the delivery of every file uploaded to your account. Any file on Uploadcare can be accessed by using UUID-based URLs,
You can notice the original filename is still there: at the very end of the URL.
In fact, you can put any file name after the trailing
/. This can be helpful
when doing SEO or using custom names for processed file versions.
For instance, the image file in the above example is processed. We optimized it
for faster delivery by adjusting its size and quality. Take a look at those
URL directives. Same stuff can be applied to videos. All that relates to our
next concept, Processing.
The Uploadcare Image Transformations are coupled with our
File transformations are performed on-the-fly, and multiple caching layers are
used to ensure popular files are delivered even faster.
Media processing works simply by adding URL directives; we call those
operations. By using operations, you can acquire file info,
filter images and video, transform
GIFs into videos, implement
object recognition, and more.
For instance, let us enhance the above image to further increase its engagement rates on your Instagram or Pinterest,
Well, not really. There is much more. You can implement Uploadcare via our Libraries and Integrations or even operate on the lowest level via our REST API that also allows you to implement extra security features to instantly get your system PrivacyShield, GDPR, HIPAA or SOC2 compliant.
Don’t spend weeks on what you can do in minutes.
