Why are good GIFs hard to make?
GIF is from 1987. It stores each frame as an indexed image with at most 256 colours, compressed with LZW, a lossless scheme designed for flat graphics, not camera footage. A video frame can contain tens of thousands of distinct colours, so turning video into GIF means choosing which 256 to keep and faking the rest.
Bad converters use a generic web palette and produce the familiar blotchy, banded GIFs. This converter runs two passes: first it analyses your whole clip and builds a palette from the colours that actually appear in it, then it maps every frame onto that palette with ordered (Bayer) dithering, which blends neighbouring colours to suggest the missing shades with a fine, stable pattern that doesn't crawl from frame to frame.
What size should a GIF be?
GIF file size grows with width × height × frames, so the size setting matters more than anything else:
- Small: 320 px wide, 10 frames per second. For reactions in chats, forum posts and comments. A 3-second clip is usually under 1 MB.
- Medium: 480 px wide, 12 fps. The best all-rounder for blogs, documentation, Slack and email. A 5-second clip is usually 1–4 MB.
- Large: 640 px wide, 15 fps. Smoothest motion and most detail, for product demos and tutorials. Expect 3–10 MB for 5 seconds.
Keep it short
Every second of GIF costs real megabytes, because GIF compresses nothing between frames: each frame is stored almost from scratch. A 3-second loop is a GIF; a 30-second one is a 40 MB file that loads slowly and many sites will refuse. Pick the moment that matters with Set start and Set end. Two to six seconds covers almost every reaction, demo or highlight.
If you need longer animations, MP4 is the better format: it's 5–10 times smaller for the same clip, and most platforms that show 'GIFs' actually play MP4 behind the scenes. Twitter/X, for example, converts uploaded GIFs to MP4.
Which clips make good GIFs?
Some footage turns into small, crisp GIFs; some fights the format every step of the way:
- Screen recordings of interfaces: flat colours suit the 256-colour palette and come out crisp and small.
- Short reactions and expressions: faces with a mostly still background compress well.
- Product shots on plain backgrounds.
- Harder cases: fast camera pans, confetti, water and smoke change almost every pixel every frame, so they make big, noisier GIFs. Use Small and a shorter clip for those.
Looping and playback
The GIF is set to loop forever, which is what every browser, chat app and social site expects. There's no sound, because GIF can't hold audio. Frame timing follows the chosen frame rate. Very high frame rates aren't worth it: browsers slow down GIF frames shorter than 20 ms, so a GIF can't play smoothly at 60 fps anyway.
Private and watermark-free
Many free GIF makers upload your video and stamp a logo on the result. This one runs ffmpeg inside your browser: the video is read from your device, the GIF is built in memory and you get a preview before downloading. There's no watermark and no upload. You can make a GIF from a TikTok, Instagram or Facebook video by saving it first with one of our downloaders.
Can I make a GIF on my phone?
The converter works in Safari on iPhone and Chrome on Android. On iPhone, tap Choose a file and pick the video from your photo library; the finished GIF is saved to Files → Downloads. To post it, share it from Files into the app you want. On Android, the GIF lands in Downloads and appears in your gallery.
Some apps change GIFs on the way through. WhatsApp, for example, converts GIFs to short looping MP4 videos when you send them, and many social networks do the same after upload. That's expected and doesn't affect quality much, because the GIF is usually the lower-quality of the two anyway.
