optipng home page
optiPNG is a PNG optimizer that recompresses image files to a smaller size, without losing any information. This program also converts external formats (BMP, GIF, PNM and TIFF) to optimized PNG, and performs PNG integrity checks and corrections. If you wish to learn how PNG optimization works, or to know about other similar tools, see the PNG Tech article A guide to PNG optimization. DOWNLOAD opti

Performance Tuning PostgreSQL
Introduction PostgreSQL is the most advanced and flexible Open Source SQL database today. With this power and flexibility comes a problem. How do the PostgreSQL developers tune the default configuration for everyone? Unfortunately the answer is they can't. The problem is that every database is not only different in its design, but also its requirements. Some systems are used to log mountains of da
pngquant Home Page
pngquant is a command-line* utility to quantize and dither 32-bit RGBA PNGs down to 8-bit (or smaller) RGBA-palette PNGs, usually with a significant reduction in file size. (Other PNG image types, even colormapped images, may also be processed, but they will first be expanded to RGBA, which isn't the most efficient way to do so.) This is the same technique used for many of the images on the Miscel
PNGCRUSH
[DOWNLOAD] [CHANGELOG] Pngcrush is an optimizer for PNG (Portable Network Graphics) files. It can be run from a commandline in an MSDOS window, or from a UNIX or LINUX commandline. Its main purpose is to reduce the size of the PNG IDAT datastream by trying various compression levels and PNG filter methods. It also can be used to remove unwanted ancillary chunks, or to add certain chunks including
How To Optimize PNG — Smashing Magazine
This post describes some techniques that may help you optimize your PNG-images. These techniques are derived from laborious hours spent on studying how exactly the PNG encoder saves data. We’ll start with some essentials about the PNG format and will then move to advanced optimization techniques. As a web designer you might be already familiar with the PNG image format which offers a full-featured
ImageOptim — better Save for Web
ImageOptim makes images load faster Removes bloated metadata. Saves disk space & bandwidth by compressing images without losing quality. Faster web pages and apps Reduces image file sizes — so they take up less disk space and download faster — by applying advanced compression that preserves quality. Image files scrubbed clean Removes invisible junk: private EXIF metadata from digital cameras, em
