100MB Target - Perfect for Email & File Sharing
Most email providers allow 25-100MB attachments. Compress to 100MB to maximize quality while staying under limits.
Compress Video to 100MB
Why 100MB Matters
Email Provider Limits
- Gmail: 25MB (via attachment), 10GB (via Google Drive link)
- Outlook: 20-100MB depending on plan
- Yahoo: 25MB attachment limit
- ProtonMail: 25MB on free, 500MB on paid
100MB Strategy
- Works for most business email providers
- Good balance of quality vs. file size
- Can fit 3-10 minutes of HD video
- Fast upload even on slower connections
How Much Video Fits in 100MB?
| Video Quality | Duration in 100MB | Best Use Case |
|---|---|---|
| 4K (3840x2160) | ~1-2 minutes | Short clips, demos |
| 1080p HD | ~5-8 minutes | Presentations, tutorials |
| 720p | ~10-15 minutes | Longer content, webinars |
| 480p | ~20-30 minutes | Training videos, lectures |
Recommended: 1080p for 5-8 Minutes
This gives excellent quality for computer/tablet viewing while fitting typical presentation or demo video lengths. Most business use cases fit perfectly.
Step-by-Step: Compress to Exactly 100MB
- 1Check Original File Size
Right-click video → Get Info (Mac) or Properties (Windows). If it's 150-500MB, easy to compress to 100MB. If it's 5GB+, you'll need more aggressive settings.
- 2Use MediaOptim Target Size Feature
Drag video → Select "Target File Size" → Enter 100MB. The software calculates optimal bitrate automatically.
How it works:
- • Analyzes video duration, resolution, codec
- • Calculates max bitrate to hit 100MB exactly
- • Adjusts quality settings to maintain best possible quality
- • Result: 99-101MB (within margin of error)
- 3Choose Codec: H.265 vs H.264
H.265/HEVC (Recommended)
- • 50% better compression than H.264
- • Better quality at same file size
- • Works on all modern devices (2018+)
H.264 (Universal)
- • Works on all devices (even old ones)
- • Slightly lower quality at 100MB
- • Use if recipient has old device
- 4Process and Verify
Click "Compress". Processing takes 1-5 minutes depending on video length. Verify output is 99-101MB (small margin is normal).
- 5Test Quality Before Sending
Watch compressed video at full screen. Check fast-motion scenes for artifacts. If quality is acceptable, you're done.
Too much quality loss? Try 150MB target or reduce video length instead of quality.
Alternative: If Video Won't Fit in 100MB
Option 1: Trim Video Length
Cut unnecessary intro/outro or split into 2-3 shorter clips. Better to send 3x 100MB videos than 1x 300MB video at awful quality.
Option 2: Use Cloud Link Instead
Upload to Google Drive/Dropbox/WeTransfer, send link. Preserves full quality, no size limit. Recipient downloads when ready.
Pro: Full quality preserved • Con: Requires extra step for recipient
Option 3: Lower Resolution
If video is 4K, reduce to 1080p. If 1080p, reduce to 720p. Quality loss is often imperceptible on smaller screens.
FAQ
Can I compress to exactly 100.0MB or will it vary slightly?
It will vary 99-102MB typically. Video encoding isn't perfectly predictable due to frame complexity variations. MediaOptim aims for 100MB and typically lands within 2% margin (98-102MB).
Will quality be acceptable for business presentations?
Yes, for 5-8 minutes of 1080p content. Text remains readable, motion is smooth. Avoid if video has lots of fine detail (small text, complex graphics) - those benefit from higher bitrates.
What if I need under 25MB for Gmail?
See our Compress to 25MB guide. For Gmail specifically, consider using Google Drive link (up to 10GB) instead of direct attachment.
Can I batch compress multiple videos to 100MB each?
Yes. MediaOptim supports batch processing with target file size. Add multiple videos, set 100MB target, process all at once. Each video compresses to ~100MB independently.
Compress to 100MB Automatically
Set target size, click compress. MediaOptim calculates optimal settings to hit 100MB exactly while maximizing quality.
