ThunderSoft GIF to SWF Converter is a reliable application that you can use when you need to batch-convert animated GIF files. This program has a pleasant design: all the functions are at sight, making the application look very organized. Besides the .gif extension, the tool also works with .jpeg, .png, and .bmp formats. It can convert multiple images at once, which is quite useful. The software provides a preview of the resulting file, allowing you to see it frame by frame.
The most important aspect of this program is that it gives you an ability to edit your files however you like. You can change the resolution, the frame rate, and you can also add a background music or color. It can add your personal logo to the converted file as well. Another nice thing is that you can extract the GIF file into a sequence of static images, splitting your file into .bmp, .jpeg, or .png frames.
In conclusion, I think the developers did a good job. The app's features do make up for its minor drawbacks; still, I think that more supported formats and maybe some themes would have been a welcome improvement.
