+### Lottie to GIF
+ThorVG provides an executable `lottie2gif` converter that generates a GIF file from a Lottie file.
+
+To use the `lottie2gif`, you must turn on this feature in the build option:
+```
+meson setup builddir -Dtools=lottie2gif
+```
+To use the 'lottie2gif' converter, you need to provide the 'Lottie files' parameter. This parameter can be a file name with the '.json' extension or a directory name. It also accepts multiple files or directories separated by spaces. If a directory is specified, the converter will search for files with the '.json' extension within that directory and all its subdirectories.<br />
+<br />
+Optionally, you can specify the image resolution in the 'WxH' format, with two numbers separated by an 'x' sign, following the '-r' flag.
+<br />
+Both flags, if provided, are applied to all of the `.json` files.
+
+The usage examples of the `lottie2gif`:
+```
+Usage:
+    lottie2gif [Lottie file] or [Lottie folder] [-r resolution] [-f fps]
+
+Flags:
+    -r set the output image resolution.
+    -f specifies the frames per second (fps) for the generated animation.
+
+Examples:
+    $ lottie2gif input.json
+    $ lottie2gif input.json -f 30
+    $ lottie2gif input.json -r 600x600 -f 30
+    $ lottie2gif lottiefolder
+    $ lottie2gif lottiefolder -r 600x600
+    $ lottie2gif lottiefolder -r 600x600 -f 30
+```
