grew tremendously over the years.
To reduce bandwidth requirements, these libraries are usually minified and GZIP compressed.
Surprisingly, most Content Delivery Networks (CDNs) give you a quite bad level
of GZIP compression.
(open source) is currently the best GZIP compressor and produces the smallest files.
It produces files fully compatible to the DEFLATE algorithm (used by GZIP) but in order to find even better compression
it is based on a random walk (trial-'n'-error
I run a brute-force search to find optimal Zopfli parameters.
That means: when decompressed by the browser, my files are 100% identical to the original minified versions.
There is no difference to the developer, to the administrator or to the end-user:
except my files are smaller and therefore load a tiny bit faster.
size(mine) < size(original) but content(mine) = content(original)
Everything you find on the website can be used in in non-commercial as well as commercial projects without any obligations
However, if you are a super-kind person, then please send me a short mail. Or a postcard. Or both.
My server analyzed these already minified and zipped projects and compressed them even further:
On average, my files
than the smallest files you find on these major public content delivery networks:
Not a single file
from these CDNs is smaller or has the same size as my compressed files.
How To Use It
Select your desired library from the table above, for example
hotlink to my server's copy
- download the smallest file and store it on your server
As mentioned before, after decompression my files are 100% identical
to their original version.
The only difference is I spent much more time finding the (almost) optimal compression.
No matter which CDN you use, it's always a good idea to have a fallback in case the CDN is unreachable or - even worse -
delisted your specific library.

You can try another CDN instead of falling back to your local server, too.
I created this website as a hobby project because every time a byte is wasted, a kitten cries. Seriously ;-)
By the way: if you run a small website it's totally fine to hotlink to the compressed files on my server.
However, high-traffic websites should copy my files to their own server.
And in the best of all worlds, major CDNs would replace their (too) large versions ... well, I'm just dreaming.
