How to Convert Video to GIF Free — Complete Guide (2026)

You want to turn a video clip into a GIF — for a Slack reaction, a blog post, a social media reply. Here is exactly how to do it, including the settings that keep your GIF small enough to actually share.

Step-by-Step: Video to GIF

1. Drop your video (MP4, MOV, WebM, AVI) into the converter
2. Set start and end time — aim for 3-8 seconds. GIFs over 10 seconds get very large
3. Choose dimensions:
   • 320px wide — Slack, Discord, messaging (small file)
   • 480px wide — Reddit, forums, general sharing
   • 640px wide — Blog posts, presentations
4. Set frame rate — 10-12 FPS for most uses, 15 FPS for smoother animation
5. Convert and download your GIF
6. Too large? Compress the GIF to reduce size further

GIF Size Calculator

Approximate file sizes for a 5-second clip:

Dimensions	10 FPS	15 FPS	24 FPS
320x240	1-2MB	1.5-3MB	3-5MB
480x360	2-4MB	3-6MB	5-10MB
640x480	4-8MB	6-12MB	10-20MB
800x600	6-12MB	10-18MB	15-30MB

Sweet spot: 480x360 at 10 FPS = 2-4MB. Small enough for most platforms, large enough to see clearly.

Platform File Size Limits

Platform	Max GIF Size	Recommended Dimensions	Notes
Slack	No hard limit, but 50MB max file	480x360	Auto-plays in channel
Discord	10MB (free), 50MB (Nitro)	480x360	Use Nitro for larger GIFs
Twitter/X	15MB	480px wide max	Auto-converts to MP4 for playback
Reddit	20MB	640px wide	Uploads to i.redd.it
iMessage	No hard limit	480x360	Large GIFs may not send over cellular
Email	~2MB recommended	320x240	Many email clients block large GIFs

GIF vs MP4 vs WebP — Honest Comparison

Format	File Size (5s, 480px)	Color Depth	Compatibility	Best For
GIF	3-6MB	256 colors	✓ Universal	Messaging, reactions, forums
MP4	300-600KB	✓ Full color	Most platforms	Web, social media, quality-matters
WebP	1-2MB	✓ Full color	Modern browsers	Web — best balance of size and quality

If your GIF is over 5MB, consider using our GIF to MP4 converter for a 90% smaller file that looks better.

Advanced: Perfect GIF Workflow

1. Trim the video to the exact clip first (easier than setting time in the GIF converter)
2. Need speed change? Speed up or slow down the clip
3. Convert to GIF at 480px wide, 10-12 FPS
4. Compress the GIF if it is over your platform limit
5. Want a boomerang effect? Reverse the GIF and combine

Creating GIFs from Images Instead

If you have a sequence of images (screenshots, slides, frames), use Images to GIF instead — upload your images, set the frame duration, drag to reorder, and download the animated GIF.
