These are required-reduction calculations, not claimed results. 500MB to 98MB needs about an 80% reduction; 1GB to 98MB needs about 90%. Large files use more memory and processing time, so keep the device powered and the tab open.
500MB → 98MB
≈ 80% reduction
1GB → 98MB
≈ 90% reduction
Compress video with no server upload
Your selected video is processed on your device, not sent to a compression server.
Compress by percentage or target MB
Choose roughly how small the MP4 should be. The compressor accepts smaller results instead of chasing an exact file size.
Load online, process locally
Keep a connection available to load the page and video engine. Local processing does not guarantee offline access.
Compress MP4 to under 100MB with a large-file preflight
Use compress MP4 to under 100MB when a large recording needs a lighter delivery copy. The page calculates reduction, bitrate, resolution, and estimated processing time from your source.
Compress MP4 to under 100MB with a 98MB target
The compress MP4 to under 100MB workflow shows 100MB as the external limit and 98MB as the encoder target. The 2% margin is used for the final hard check.

Compress MP4 to under 100MB from 500MB
A 500MB source must shrink about 80% to compress MP4 to under 100MB at the 98MB safety target. This is a calculation, not a claimed quality result.

Compress MP4 to under 100MB from 1GB
A 1GB source must shrink about 90% to compress MP4 to under 100MB. Device memory, source duration, and motion decide whether 1080p or 720p is realistic.

How to compress MP4 to under 100MB
To compress MP4 to under 100MB, check the source size and estimated time first, then inspect the duration-based bitrate before choosing Auto, 1080p, or 720p.
Preflight the file to compress MP4 to under 100MB
Choose MP4, MOV, M4V, WebM, or MKV. The compress MP4 to under 100MB tool reads size, duration, and dimensions locally and estimates processing time.
Review bitrate to compress MP4 to under 100MB
The compress MP4 to under 100MB panel calculates total bitrate, audio reserve, video budget, required reduction, and expected output dimensions.
Choose 1080p or 720p to compress MP4 to under 100MB
Keep Auto when compress MP4 to under 100MB is feasible. Cap at 1080p or 720p when a long or very large source needs more useful detail per pixel.
