Tutorials

Vector graphics tutorials

Application

  • SVG with Inkscape - Fully featured SVG drawing program, also capable of PNG output
  • Using Dia - page not maintained - Well suited to technical diagrams & flowsheets - PNG output, limited SVG support
  • Using Microsoft Word - page not maintained - Familiar to many users, easy to use - PNG only, no SVG support

Specific tasks

Photo editing tutorials

Combination tutorials

Filesize optimisation tutorials

Open source programs

  • PNGCrush - Old tried and true program that reduces PNG sizes using multiple zlib compression trials on disk.
  • OptiPNG - Essentially a newer version of PNGCrush, it economizes the trial (reducing from 100s of short ones to a maximum of 7 longer ones) and does everything in memory. Usually produces identical results, and is much faster.
  • AdvanceCOMP - A group of programs designed to reduce ZIP compression in many contexts, including PNGs (using AdvPNG).
  • Jhead - A program for viewing, altering, or removing Exif data of JPEGs. Amongst other things, this allows for reducing file sizes.
  • FileOptimizer - A Windows GUI program (recommended for beginners) that uses multiple open source and freeware tools (including most of those listed here) to optimize a large number of media filetypes. Achieves better compression than any of the others used by themselves. Released under the LGPL.

Freeware programs

  • PNGOUT - A program that optimizes PNGs by eschewing the usual zlib compression for a slower but more complete algorithm.
    • PNG Gauntlet - GUI for OptiPNG, PNGOUT, and DeflOpt (similar to AdvPNG in AdvanceCOMP)
  • Image Analyzer - Amongst other things, allows for lossy compression of PNG files. (Often, however, merely posterizing the image at a level that does not produce color banding results in smaller files of the same or higher quality.)
  • JPG Cleaner - Removes Exif data from JPEGs, making the files smaller.
  • JPGExtra and PNGExtra - Programs that losslessly optimize JPEGs and PNGs by cleanly removing all non-image data.
