ThunderSoft GIF Joiner is an intuitive application that allows you to combine several animated GIF files into a single one.

Multiple source formats supported

Despite its name, the utility can be used to process several additional formats, such as BMP, PNG and JPEG. In other words, you can merge animated files with static images.

You only need to add the items you want to join, by manually browsing to their location since drag and drop actions are not supported. Once you have created a list within the main window of ThunderSoft GIF Joiner, you can re-arrange files by moving them up or down, depending on the position you want them to occupy.

Adjust speed and replay times

Before saving the created GIF, you can choose the target folder and assign the output file the name you prefer.

Additionally, you can keep the original speed for each source animated GIF, or you can set it at 20%, 50%, 150%, 200%, or 300%.

You can also modify the replay times for each frame, ranging from 0 to infinite. Another parameter that can be altered is how long each image is displayed for (you can enter the time in seconds).

Conclusion

All in all, ThunderSoft GIF Joiner can come in handy to all those looking for a quick way to merge several animated GIF files into a single one, while also throwing some static frames in the mix.

Nonetheless, no effects editing operation are supported, so there is no enhancing that can be made prior to the conversion to GIF. If this is what you need, you might want to look for a different solution.
