Learn How to Optimize Flash Files

This tutorial provides simple step-by-step guide to Flash optimization.

1. Browse to the SWF file you want to optimize using File Manager panel or File –> Open and add it to the Task List panel.
2. Customize optimization parameters.

Flash Optimizer uses two different approaches to the process of involving users to optimization.

The first one is very simple and partially universal and was designed for typically structured SWFs: choose an Optimization set provided with Flash Optimizer. Optimization sets are simple files that store information about which Optimization parameters were selected and which ratios and margin values were used. Every Optimization set can have a name, can be saved, loaded, or deleted.

So, if you are unsure of what optimization parameters will be the best for your particular SWF file, we advise applying one of predefined Optimization sets, created by developers of Flash Optimizer. Flash Optimizer currently offers the following Optimization presets:

  • default – optimal compression settings for a SWF file
  • Best compression – Lower quality
  • Basic compression – No quality loss
  • Good compression – Middle quality
  • Sprite compression (for SWFs with embedded images)
  • Fine compression – Good quality

The second approach lets you customize every single parameter of Flash Optimization. Note, that we recommend joining both approaches for the best results. Probably you might find it very helpful to load one of the existing Optimization sets at first and then apply some manual customization to find the best compression settings for your SWF.

1. Click “Optimize current task” button on the main toolbar to be able to preview SWF file optimization or “Optimize all tasks” to proceed with compression and save the results to the hard drive.


If you are not satisfied with the optimized file quality, select different optimization settings and repeat this step.

2. Click “Save” or “Save As” toolbar buttons to save optimized Flash file. In case you have clicked “Optimize all tasks” button, you may omit this step: all files were automatically saved in the same folder with suffix you have set in “Preferences”.

Please, note that the demo version saves files in monochrome (grayscale) mode only and as a result, an optimized file can be smaller in size than the one which was optimized with the registered version, which preserves colors, however it could be even larger. For proper comparison please use “SWF Info” button. Additionally, make sure that ActionScripts work correctly after optimization – we advise you to disable Scales optimization.
