Step-by-step Guide for Optimizing Flash files

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

1. Browse to SWF file you want to optimize using File Explorer and add it to Task List panel:


2. Select target folder to save the result:


3. Select desirable filename:


Note, that SWF extension is required

4. Customize optimization parameters.
Flash Optimizer uses 2 different approaches into the process of involving users to optimization. First one is very simple and partially universal and was designed for typically structured SWF’s. This is when you 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 stipulated. 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 settings preset:


  • Best compression – Lower quality
  • Good compression – Middle quality
  • Basic compression – Partially quality loss
  • Medium compression – Good quality
  • Sprite compression (for SWF’s with embedded images)
  • Custom compression – establish quality manually and save settings for subsequent optimizations

Second approach lets you customize every single parameter of Flash Optimization. Note, that we recommend joining both approaches for best results. Probably you might find it very helpful to load one of existing Optimization sets at first and then apply some manual customization to find the best compression settings for your SWF. At this point it is very important for you to understand that we greatly encourage experiments and applying absolutely unexpected settings. Bold experiments in Flash Optimizer are the only way to truly master all its functions. So don’t hesitate and straight click every “red button” you come across.

5. Click “Preview compression” button to preview SWF file optimization and compare with original movie.

Use “Switch to optimized/original info” and “Details” buttons to compare original and optimized movie. Then click “Compress” button to proceed to compression and save the result on the hard drive (click “Compress all” button if you would like to optimize batch of Flash movies).




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