Screen Recording to GIF: The Developer's Guide for GitHub, Slack & Docs

A well-placed GIF in a GitHub PR description communicates more than three paragraphs of text. Here's how to go from screen recording to shareable GIF in under two minutes — optimized for GitHub, Slack, Notion, and technical docs.

Why GIFs Beat Videos in Developer Contexts

• GitHub: Renders GIF inline in PR descriptions and issues — no click-to-play
• Slack: Auto-plays in threads — no one clicks a video link
• Notion/Confluence: GIFs embed natively; videos require iframes
• README files: GIFs render on GitHub, npm, and any Markdown viewer without a player

Step 1: Record Your Screen

macOS

• Built-in: Cmd + Shift + 5 → select area → Record
• Output: .mov saved to Desktop
• Tip: Record only the relevant window, not the whole screen

Windows

• Built-in: Win + G (Game Bar) → Record → .mp4 saved to Videos/Captures
• Better: OBS Studio (free) → outputs .mp4

Linux

• OBS Studio → .mp4
• Or: ffmpeg -f x11grab for terminal-based capture

Browser

• Chrome DevTools → More Tools → Recorder → exports .webm
• Loom extension → .mp4 download

Step 2: Upload to the Converter

Open Moxion Screen Recording to GIF. Drag your file onto the upload area — .mp4, .webm, .mov, and .avi all work, up to 100 MB.

Step 3: Trim to the Key Moment

Use the start/end sliders to cut to exactly the interaction you want:

• Bug reproductions: 3–6 seconds showing the failure
• Feature demos: 4–8 seconds of the happy path
• UI animations: 2–4 seconds of the interaction

Tip: Keep GitHub GIFs under 10 MB — GitHub renders them inline up to 10 MB. Larger files show as a download link.

Step 4: Optimize for Your Use Case

Use case	FPS	Width	Lossy compression
GitHub PR	10–12	800–1000px	60–80
Slack thread	12–15	640–800px	50–70
Notion/docs	8–12	800px	60–80
README (npm/GitHub)	10	640–800px	70–80
Tutorial with text	12–15	1000–1200px	40–60

For finer control, open Advanced Studio to set dithering, color count, and compression.

Step 5: Export and Share

Click Export GIF, then:

GitHub PR
Drag the GIF file directly into the PR description text area. GitHub hosts it automatically.

Slack
Click the attachment icon → select your GIF. It embeds inline and auto-plays.

Notion / Confluence
Drag the GIF into your page. Both render it as an animated image.
