Most users computer systems, one way or another, came across Flash animation. Many cartoons, banners on websites, or even simple Internet games are made in this format. But what are SWF files and how are they created or edited if some changes need to be made to the finished project? This and much more will be discussed further.

What are SWF files?

Few people think about what a SWF animation file actually is, considering it an ordinary video.

In fact, the files themselves are compiled derivatives of the original FLA format, which in turn is a project in which the original structure can be seen and modified. Naturally, this requires some SWF editor-files. But which one? Today, so many programs have been created for creating and editing Flash animation that it is quite easy to get confused in them.

How to open a SWF file?

We'll get back to the editors a little later. For now, let's look at how to open a SWF file in the simplest situation. There are at least two options: either use some kind of software player that supports this format(KMPlayer), or start playback in a web browser.

In the second case, for correct playback, a prerequisite is the presence of the installed Flash Player plugin from Adobe or its equivalent in the form of a Macromedia Flash extension, which is, in general, the same thing.

The principle of editing a finished Flash video

Now a few words about how editing is carried out in general terms finished project. An editor for SWF projects of the most primitive type will not be able to simply open a file, since the finished SWF file, as already mentioned, is compiled and contains a minimum of information about the initial structure.

Thus, before using the simplest SWF file editor, the finished file must first be converted, so to speak, into readable form. In other words, it needs to be decompiled into its original FLA form. For this purpose, special utilities are used, which will be discussed separately.

The best editors for creating animation from scratch

Nevertheless, to create a video (and not edit it) at the initial stage, the most simple applications, and entire professional-level software packages.

It will not be possible to describe them all, but among the programs designed for this purpose, several of the most popular can be identified:

  • Alligator Flash Designer.
  • SWiSH Max.
  • Adobe Flash Professional.
  • Corel R.A.V.E.
  • Sony Vegas Pro.

Alligator Flash Designer

This SWF editor in Russian is the simplest of all those presented below and is intended mainly for quickly creating animated banners that will be used on websites on the Internet.

There are not so many tools at the disposal of a novice web designer, however, there are about one hundred and thirty different effects, the ability to create animated text, drawings or insert sound. The interface is extremely simple and clear, so this application is very well suited for mastering the basics of creating animation of this type.

SWiSH Max

This animation file editor is very similar to the previous utility, although it looks a little more complex for a beginner.

With its help you can create more professional works of good quality. Any user can figure it out thanks to the fact that the application itself includes video tutorials that explain the basics of creating animated videos.

Adobe Flash Professional

The Adobe Flash SWF file editor is a professional-level software package that not everyone can master the first time.

He has so many tools in his arsenal that, according to many professional web designers and animators, you can use them to realize any fantasy. By the way, if you look at the world rankings software this direction, namely Adobe applications Flash CS and CC series are the undisputed leaders.

Corel R.A.V.E.

Here we have another professional SWF editor with capabilities comparable to the previous package from Adobe.

The most interesting thing is the ability to draw two-dimensional objects, determine their movement along a predetermined path, snap to the specified path, create a double of the animated object to change only the size, color or location, after which the program automatically performs the necessary transformations and animates the image. Naturally, this is not all that this application is capable of. You can study it and admire more and more new possibilities for a very long time.

Sony Vegas Pro

This video processing package certainly needs no introduction. Even those who have never worked with this type of multimedia know about it. Of course, this is not a SWF editor as such, but it does have tools for creating animation, and they are very worthy of attention.

The program allows you to create and edit animation videos (in this case the emphasis is on them) using more than 200 effects, editing can be done based on 8-bit mode, and at the finalization stage you can switch to 32-bit to improve quality. You can also apply color filters to eliminate differences in different fragments, set the storyboard frequency at 30 fps or higher, and also set a variety of image aspect ratios, including even transformations and transitions between them (4:3, 16:9, 16: 10), etc. In general, there are enough tools.

Additional utilities for working with Flash

Speaking about creating and editing animated videos, we cannot ignore some additional utilities that may be useful in your work. In particular, this concerns the conversion of the final SWF file to the original FLA project format through decompilation (formatting the code), as well as some additional tools used to improve image quality and reduce size final file without loss of quality.

Among the most necessary programs The following can be noted:

  • Flash Decompiler Trillix.
  • Sothink SWF Decompiler.
  • Flash Optimizer.
  • Sparkle SWF Optimizer.

Flash Decompiler Trillix

A novice user will need this program to convert a SWF file to FLA format so that the project can be opened even in the most simple editor and make the necessary changes to it.

Essentially, this is an advanced converter with editor capabilities in which changes can be made on the fly. You can also use it to perform batch conversions. And all this is done without the mandatory installation of Adobe and Macromedia plugins.

Sothink SWF Decompiler

This program is also a decompiler-editor, albeit a paid one. Its capabilities are very interesting. It is focused on quick creation or editing banners, videos and even Flash games.

For beginners, the application provides a special “Wizard” based on the choice of the type and structure of the future project from the available templates. In addition, you can work with the source code, apply all kinds of filters, effects, or create vector images in a special WYSIWYG environment.

Flash Optimizer and Sparkle SWF Optimizer

These two small utilities, as the name suggests, are some kind of optimizers that allow you to reduce the size of the finished SWF file to save space without losing quality. They will be especially useful to all those who post their work on the Internet or create banners and online games in Flash format.

As stated on the official websites of the developers, these utilities allow you to perform compression and reduce the size of the original object by as much as 70%. They have several types of optimization using automatic conversion after setting the necessary parameters.

What to use?

Finally, the most important question: “What to choose from all this?” We think that novice animators and web designers should start with the simplest utilities. For those who have at least a little knowledge of creating and editing SWF videos, professional utilities will undoubtedly be suitable. Here the choice is up to the user. However, if you wish and study reference information, which is available in most of the applications presented, you can master working with them very simply. But which editor is better? The palm rightfully belongs to the developments of Adobe, although other editors and decompilers should not be discounted.

→ Sothink SWF Quicker

Sothink SWF Quicker - powerful utility to work with flash. If we consider it for animation, it is better to look towards the Adobe product line. But for working with flash applications it is indispensable. In essence, this is a full-fledged editor for flash, but its main feature is convenient work With swf format. With its help you can open a swf file and edit it Action-script and save. It is very convenient if you need to change the mp3 player to flash to suit your needs by introducing a couple of your own functions into its source code.

It was like this. An mp3 player for online listening to music was introduced on one of the entertainment portals. The customer's requirements were completely achievable. The player had to be able to work with a playlist and have standard set buttons The choice fell on Dewplayer. Everything was going great, cross-browser compatibility was excellent and the work was nearing completion. But suddenly a minor problem arose - the player was made by the French and apparently they did not expect to include support for the Cyrillic alphabet. That is, when playing the track, the Russian characters in the running line with the name of the song were “krokozyabla”. I didn’t want to give up the work I had done and a solution was found.

Dewplayer has a wide range of features, including javascript support. This means you can access the player’s methods through js. Therefore, if you implement your methods in Action-script, the output will be all the necessary functionality. And it was necessary to create a function that would return the name of the current track.

So download and install Sothink SWF Quicker. Let's launch. In the tab File choose a position import.

In the window that opens, set the file type .swf and click on “patient”.

After selecting a file, the program may warn that the file is protected and ask: should I import anyway? The answer is yes. After the swf file is opened, look at the lower right corner. Click on the tab Action. We get an Action-script available for editing. I won’t read lectures on flash programming, I’ll continue on my own)).


After making changes, we perform the reverse procedure - export. On the top panel we find the tab Export. IN context menu click on Export Movie. Next we save it in new file or replace the one that is open.


SWF (Small Web Format) is a proprietary video format used for Flash animation, vector graphics, audio and video content on the Internet.

The advantage of the format is its small size; due to this, videos in SWF format load and play faster, and vector images are scaled without distortion.

The scope of use is quite diverse - banners, websites, lightweight games (for example, social networks), presentations, cartoons.

Opening SWF files using a browser

Almost any browser can be used to open SWF files ( Google Chrome, , , Safari, etc.).

However, it is worth mentioning that Flash player must be installed in the browser. In some it is installed by default, i.e. By installing a browser, you also install a Flash player.

To open a SWF file, simply drag 'n' drop it into the browser window. If the file does not open, you may need to update your browser's Flash player.

The advantage of opening SWF files using a browser is quick view file, without the need to download special software (usually the Flash player is already installed in the browser).

The disadvantage of viewing SWF files in a browser is the relatively low functionality (the ability to pause, rewind, stop video sequences) compared to players.

Opening SWF files using Flash player

There are quite a large number of paid and free Flash players that can be found on the Internet. The functionality of free players is essentially no different from their paid counterparts.

Quite a popular program, although no, it’s not just a program, but a whole multimedia combine, from Korean developers, which, in addition to viewing SWF files, supports most modern multimedia formats.
