Keep it short
Use the smallest useful moment.
A reaction, demo or tiny loop usually works better than converting a whole clip just because you can.
Video, GIF & Audio
Pick the short bit you need, choose the frame rate and size, then export a looping GIF.
Choose a short video.
Worth knowing
The shorter and smaller the selection, the better the result. GIFs become huge quickly because they are much less efficient than modern video.
Keep it short
A reaction, demo or tiny loop usually works better than converting a whole clip just because you can.
Keep it sensible
A smaller GIF often looks almost identical in a chat or post while weighing a fraction of the file size.
If GIF is not required
If the platform accepts video, repeating a short MP4/WebM-style clip is usually lighter and smoother than GIF.
What next?
Use the result you just made as the starting point, not a reason to open a full editor.
Useful to know
Media exports combine dimensions, frame or sample rate, codec, bitrate and duration. File size is the result of those choices, not one magic quality switch.
A browser utility is good for a focused conversion or edit, but it is not colour grading, audio mastering, motion tracking or a full timeline.
Play the exported file from beginning to end and check picture, sound, crop, timing and orientation.
Play the export all the way through once. Broken audio, a bad final frame or a mistimed subtitle often hides near the end.
