GIF Sender
Send GIFs naturally in WhatsApp conversations.
CRITICAL: WhatsApp GIF Workflow
WhatsApp doesn't support direct Tenor/Giphy URLs. You MUST:
- Download the GIF
- Convert to MP4
- Send with
gifPlayback: true
Complete Workflow
Step 1: Search for GIF
gifgrep "SEARCH QUERY" --max 5 --format url
Search in English for best results.
Always get 5 results and pick the best one based on the filename/description - don't just take the first result.
Step 2: Download the GIF
curl -sL "GIF_URL" -o /tmp/gif.gif
Step 3: Convert to MP4
ffmpeg -i /tmp/gif.gif -movflags faststart -pix_fmt yuv420p -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" /tmp/gif.mp4 -y
Step 4: Send via message tool
message action=send to=NUMBER message="" filePath=/tmp/gif.mp4 gifPlayback=true
Note: Use invisible character (left-to-right mark, U+200E) as message to send GIF without visible caption.
One-liner Example
# Search
gifgrep "thumbs up" --max 3 --format url
# Pick best URL, then:
curl -sL "https://media.tenor.com/xxx.gif" -o /tmp/g.gif && \
ffmpeg -i /tmp/g.gif -movflags faststart -pix_fmt yuv420p -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" /tmp/g.mp4 -y 2>/dev/null
# Then send with message tool, gifPlayback=true
When to Send GIFs
✅ Good times:
- User asks for a GIF
- Celebrating good news
- Funny reactions
- Expressing emotions (excitement, facepalm, etc.)
❌ Don't overuse:
- One GIF per context is enough
- Not every message needs a GIF

Security & Safety Notes
- Source domains: gifgrep only searches trusted GIF providers (Tenor, Giphy)
- File handling: All downloads go to
/tmp and are overwritten each time (-y flag)
- Empty caption: The
character (U+200E, Left-to-Right Mark) is used as an invisible caption so WhatsApp sends the GIF without visible text. This is a standard Unicode control character, not an injection technique
- WhatsApp integration: Uses the platform's built-in
message tool — no separate WhatsApp credentials needed
- ffmpeg safety: Processes only GIF files from trusted providers; no arbitrary file execution
Why This Works
- WhatsApp converts all GIFs to MP4 internally
- Direct Tenor/Giphy URLs often fail
- MP4 with
gifPlayback=true displays as looping GIF
- Small file size = fast delivery
