Make iPhone videos smaller before sharing
Even a short iPhone recording can be awkwardly large when you try to share it. With 4K or a high frame rate, duration alone does not tell you how much space it needs.
Open tool →Steps
- Select videos in ClipForge and choose local or server conversion.
- Match the container, codec, resolution and video and audio settings to the destination.
- Check a short trial for sound and picture, then save the result.
File selection screen
Prepare a copy for its destination
Keep the original and make a separate sharing copy. A lower resolution may be enough for someone watching on a phone. Check brightness and colour in the saved video too.
Settings and checks
Keep the original in Photos. Try 720p or 1080p for sharing.
Where processing happens and device limits
Local conversion does not send files to the conversion server. Choosing server conversion uploads them. Local conversion supports up to 512MB; server conversion supports a combined selection up to 64GB. Memory and input codec support can cause failures even below these limits.
Troubleshooting
If playback fails, check the codec inside the MP4 container too. If size exceeds the limit, review bitrate, resolution and duration. After changing fps, inspect motion, synchronization and playback through to the end.
Frequently asked questions
Is specifying only target size or resolution enough?
No. Bitrate, duration, fps and codec affect size and quality even at the same resolution. Include audio in the size budget and inspect the exported size and playback.
