# How to turn a video into a GIF > Trim the video to a few seconds, add a caption if you want one, open Export and choose Animated GIF with a width of 480, 640 or 800 px and a length of 6, 10 or 15 seconds. Smaller and shorter loads faster and loops better. - Page: https://cutluma.com/guides/how-to-turn-a-video-into-a-gif - By the CutLuma team · Published 2026-10-10 · Updated 2026-10-10 · 3 min read - Try it: https://cutluma.com/editor?guest=1&tool=open (Make a GIF) ## Step by step 1. **Open the video** — Drop an MP4, MOV or WebM into the [video to GIF tool](https://cutluma.com/tools/video-to-gif). Screen recordings and phone clips both work. 2. **Trim to the moment** — A GIF is one gesture, one reaction or one step of a process. Drag the clip edges until only that is left. 3. **Crop if you can** — A square or tight crop with the [crop tool](https://cutluma.com/tools/crop-video) cuts the file size and makes the subject bigger in a chat window. 4. **Add a caption** — Optional: a bold text line at the top or bottom turns a clip into a meme or a labelled demo. 5. **Export as GIF** — In the export dialog choose Animated GIF, then a width (480, 640 or 800 px) and a length (6, 10 or 15 seconds, or the whole video). Download and drop it wherever you need it. ## Choosing a size GIFs store every frame as a full image, so file size grows fast with width and length. The export dialog offers three widths. 480 px is right for chat apps, comments, Slack and email, where the GIF is shown small anyway and a few megabytes keeps it snappy. 640 px suits documentation, GitHub issues and Notion pages. 800 px is for product pages and presentations where the GIF is the main content; expect a much larger file. Whatever the width, the height follows the shape of your project. A 9:16 project at 480 px wide is 480×853; a 16:9 project at 800 px wide is 800×450. Cropping to the part that matters before export is the best way to make the subject bigger without making the file bigger. ## Length and looping The lengths on offer are 6, 10 and 15 seconds, or the whole video. Six seconds is the sweet spot for reactions and most loops: short enough that the repeat feels natural. Ten seconds covers a short how-to step; fifteen is the ceiling before file size and attention both suffer. Use the whole-video option for a complete short demo and accept the large file. A GIF restarts from the first frame when it ends, so pick a start and end that look similar if you want a smooth loop: the same hand position, the same screen state. If the clip has a hard jump at the loop point, trim a few frames off either end until it settles. ## Where GIFs autoplay and where video is better The reason to make a GIF rather than an MP4 is that GIFs play automatically, silently, almost everywhere an image can go. - **Autoplay as an image:** chat apps, GitHub issues and pull requests, Slack, Notion, Confluence, most email clients and CMS editors. - **Better as MP4:** anywhere you need sound, more than 15 seconds, or sharp colour and detail, such as a social post or a landing-page hero. Export MP4 instead. - **Social apps convert anyway:** X, Facebook and many others turn uploaded GIFs into video, so upload an MP4 there and keep the GIF for places that need an image. ## Quality tips A GIF has at most 256 colours per frame, so gradients and fine photo detail can band. Clips with flat colours, screen recordings and bold text convert best. Add text in the editor rather than afterwards so it is rendered at full size; keep it big and high-contrast. Avoid fast camera movement, which makes every frame different and bloats the file. If you need a sharper result for a screen demo, record at the final size with the [screen recorder](https://cutluma.com/tools/screen-recorder) so nothing is scaled. ## FAQ **How do I make a GIF from a video for free?** Open the video in CutLuma, trim it, and choose Animated GIF in the export dialog. No account upgrade is needed. **Why is my GIF so large?** Width, length and motion. Try 480 px and 6 seconds, crop to the subject, and avoid clips with a moving camera. **Can a GIF have sound?** No. GIF is a silent image format. Export an MP4 if you need audio. **Does the GIF have a watermark?** Free exports carry the same small CutLuma badge as videos. Paid plans remove it. ## Tools used in this guide - [Video to GIF](https://cutluma.com/tools/video-to-gif) — Turn any video into an animated GIF.
