The smallest 256x256 single-color PNG file, and where you've seen it
Do you recognise these images? There's a good chance you've seen some of them before now, probably several times. Here's a hint: They all depict the same thing. 103 bytes 156 bytes 178 bytes 379 bytes 921 bytes 1,189 bytes They all look pretty similar - so why the size difference? A quick intro to PNG The basic PNG file is comprised of recurring chunks. Each chunk is comprised of four parts: Lengt
KeyJ's Blog : Blog Archive » MP3 for image compression
During some random discussion with my colleague today, I rediscovered an experiment I did quite some years ago: MP3 compression of image data. This is, feed raw 8-bit-per-pixel grayscale image data into an MP3 encoder, let it compress it, and decode the MP3 file again. After some conversion (the decoder will always produce 16 bit signed output, but 8 bit unsigned image data is needed), a raw image
BPG Image format
News (Apr 21 2018) Release 0.9.8 is available. Introduction BPG (Better Portable Graphics) is a new image format.

Kazuho@Cybozu Labs: Compressing URLs in your Webapp, for size and speed
Last year I had a chance to talk about the internals of our service: Pathtraq at Percona Performance Conference (slides), in which I described the methods we use to compress the URLs in our database to below 40% of the original size, however had not released the source code since then. I am sorry for the delay, but have finally uploaded the code to github.com/kazuho/url_compress. It is generally
punypng - PNG Image Optimization and Compression - Gracepoint After Five
* Flash required. Supported Types: JPG, GIF and PNG (Max 500KB each) What is punypng? punypng is a free optimization service that can dramatically reduce the file size of an image by converting it into a highly-compressed, lossless PNG image. That translates to outrageously efficient web page loading, and just makes the web more puny. Making the web more puny isn't cheap, so help support our cause
MonaTweeta II
MonaTweeta II Preliminary result of a little competition between me and Ralph Hauwert (who had the initial idea) with the goal to write an image encoder/decoder that allows to send an image in a tweet. The image on the left is what I currently manage to send in 140 characters via twitter. This is the tweet for the image: 圑嘌婂搒孵怤實恄幖戰怴搝愩娻屗奊唀唭嚟帧啜徠山峔巰喜圂嗊埯廇嗕患嚵幇墥彫壛嶂壋悟声喿墰廚埽崙嫖嘵奰恛嬂啷婕媸姴嚥娐嗪嫤圣峈嬻尤囮愰啴屽嶍屽嶰寂喿嶐唥帑尸庠
