Video to GIF: How to Make an Animated GIF That Is Not Huge

Updated November 3, 2026

A GIF plays anywhere — in e-mails, documents, chats and pages where a video will not start on its own. The catch is size: a few seconds of video can turn into a GIF of tens of megabytes. Here is why, and the three settings that keep a GIF small.

1. Why GIFs get so big

A video stores a full picture now and then and, in between, only what changed. A GIF stores every frame as a picture of its own, with at most 256 colours. So its size grows with three things multiplied together: how long it is, how many frames per second it has and how many pixels each frame has.

2. The three settings

Pixels in each frame of a 16:9 clip at each width, and frames in 10 seconds at each frame rate:

Width	Frame	Pixels per frame
320 px	320 × 180	57,600
480 px	480 × 270	129,600
640 px	640 × 360	230,400

Frames per second	Frames in 10 s
8	80
12	120
15	150

Put together, a GIF at 640 px and 15 frames per second has 7.5 times the pixels per second of one at 320 px and 8 frames. Halving the width alone cuts them to a quarter.

3. Good settings for each use

Reaction or meme for a chat: 320 px, 8–12 frames per second, 2 to 5 seconds.
Product demo or tutorial step: 480 px, 12 frames per second, under 10 seconds.
Screen recording with small text: 640 px so the text stays readable, 8 frames per second — screens change little between frames.
Fast movement (sport, dance) needs 15 frames per second to look smooth; keep those cuts very short.

4. Length limit

The tool makes GIFs of up to 480 frames: 60 seconds at 8 frames per second, 40 at 12 and 32 at 15. A longer cut stops there. In practice, keep it to about 15 seconds — beyond that a short MP4 is a much better file.

5. Square or vertical

In Size & frame you can crop the GIF to 1:1 (square, for chats and profiles) or 9:16 (vertical, for stories). A square GIF keeps the centre of a horizontal video, but at the same width it is taller — 480 × 480 instead of 480 × 270 — so choose a narrower width to keep it light.

6. GIF or MP4?

A GIF has no sound. If the place you are posting accepts video — WhatsApp, Instagram, most social networks — a short MP4 looks better and is many times smaller. Use GIF where video does not play by itself: e-mail, documents and slides, project pages, old chat apps.

Make your GIF

In video to GIF, drop the video, drag the handles to the moment you want (the first 10 seconds come selected), choose the width and frames per second and export. No watermark, and the video is processed by your browser and never leaves your device.
