How to make a GIF from a video that isn't huge

File size grows with every frame. Two to six seconds is enough for a reaction, a product demo or a how-to step. Trim the clip to the exact moment before converting — your phone's Photos app can do this in seconds.

A GIF 480 pixels wide at 10 frames per second looks smooth in chats and documents. Going to 640 px and 15 fps looks better but roughly doubles the size. For tiny loops in email signatures, 360 px at 8 fps is plenty. Localvert's MP4 to GIF presets use exactly these combinations.

Screen recordings, animations and shots with a steady camera and flat colors compress well. Shaky handheld video, grass, water and gradients like a sunset sky use up the 256 colors quickly, creating grain and large files.

Many places limit GIF uploads: some chat apps reject files over 8–10 MB, email providers block large attachments, and documentation sites slow down when pages carry heavy animations. Aim for under 3–5 MB for anything you will share widely. If a GIF comes out too big, shorten the clip first, then lower the size preset.

If your GIF shows text or interface steps, record at a larger zoom level so the text stays readable at 480 px wide. Move the mouse slowly and pause briefly on each step. A loop that starts and ends on the same frame looks smoother than one that jumps back to the beginning.

Chat apps, social networks and most websites autoplay short silent MP4 clips as if they were GIFs — at a fraction of the size and with full color. Use real GIFs where video isn't supported: email, some forums, documentation and README files.
