Image sharpening speed-up

cdn api November 07, 2018

We increased the performance of the sharp Image Processing operation. Image sharpening is one of the most commonly used on-the-fly operations on Uploadcare.

Our internal benchmarks show that we increased the operation performance by up to 5x. This means that the sharpening-enabled image operations will become faster when output images have not been cached by our CDN yet.

No actions are required on your end.

Increased ZIP/TAR archive limits

cdn api May 04, 2018

You can now get larger file groups as ZIP or TAR archives. A new limit of a total uncompressed size of files in a group you archive is 2 GB.

Check out our docs for details on file groups and archiving.

Video Processing

rest api, cdn api March 21, 2018

Introducing Video Processing. You can now optimize videos, transcode them, cut fragments, and generate thumbnails.

Video Processing is available to all our customers and works via REST API, here is how:

  • You post a processing job by making a REST API request; all the processing params are passed in the request.
  • Once the job is finished, you get a UUID of a processed output.
  • At the same time, the output becomes addressable via a CDN URL.

Here is what you can do with videos:

“quality” Image Processing operation update

cdn api February 05, 2018

Before the update, producing higher quality JPEGs from their low-quality originals could lead to increased output file sizes.

Now, if no destructive operations are applied, your output JPEG quality is limited to the initial input quality. I.e., when you provide low-quality JPEG inputs, using higher quality presets will neither increase file sizes nor change your initial compression. Learn more.

Convert GIF to video

cdn api July 07, 2017

You can now convert GIFs to either H.264 or WebM video formats on the fly via our new gif2video operation. Video files are generally much smaller than GIFs hence their delivery is significantly faster.

The gif2video feature is disabled by default and should be explicitly enabled for your project. Learn more in our docs.

Download multiple files as ZIP or TAR archives

cdn api June 08, 2017

Now, instead of iterating through individual files and downloading them one by one you can get a whole pack in one go. We've introduced the archive operation for that. It allows you to get groups as either zip or tar archives.

Current limits are:

  • total uncompressed size of files in a group should not exceed 100 MB
  • archives include original files only — CDN API operations info is discarded

Detect faces in your images

cdn api January 19, 2017

From this point on you can detect faces in photos with Uploadcare. We're happy to announce the detect_faces CDN API operation.

enter image description here

The operation gives you coordinates of faces found in your images in a neat JSON:

{"faces": [
  [120, 380, 560, 560],
  [1235, 310, 635, 635],
  [2375, 110, 740, 740]
]}

Use it to further improve your image workflow or build stuff from scratch!

Make use of WebP images with Uploadcare

widget, cdn api January 19, 2017

You can now upload WebP images with our widget, process those on-the-fly using Uploadcare CDN or convert your existing images to WebP by adjusting their format.

Extract colors from your images

cdn api October 28, 2016

You are now able to extract colors from your images with the main_colors CDN API operation. Basically, the operation is about analyzing an image in order to extract a given number of dominant colors as a list of RGB values.

Increased CDN limits

cdn api July 25, 2016

We've increased CDN image dimensions limits. This means that you can retrieve larger images from CDN and process larger original files from your users.

Maximum source image resolution is increased from 50 to 75 Megapixels. This allows, for example, to handle panoramas from iPhone 6s.

Maximum output resolution is increased from 2048×2048 to 3000×3000 pixels (look at this example).

Default values for -/preview/ operation stay the same, so preview without arguments will produce images with resolution up to 2048×2048 to save bandwidth.

Auto enhance via CDN

cdn api June 07, 2016

We've added an auto enhance operation to our CDN image processing API. It automatically tunes levels, contrast and sharpening.

So instead of original on the left you get enhanced version on the right:

The feature is available on all plans with no extra charge :)
