How do I compress a video to 100 MB?

Drop the video onto the compressor above. 100 MB is already set as the target (you can switch to another size or a percentage), so click Compress and download the result.

Which video formats can I compress to 100 MB?

MP4, MOV, MKV, WebM and AVI. Each file keeps its own format.

Which format should I use for a 100 MB video?

MP4 is the safest choice: it plays on every phone, browser and chat app. WebM is as efficient but less widely accepted. Compressing keeps each file's format, so convert first if the destination needs MP4.

How much quality will I lose at 100 MB?

100 MB is roomy for anything up to ten minutes or so; hour-long recordings will need a lower resolution. A 3-minute clip at 100 MB gets about 4.4 Mbps for video and audio together (1080p, high quality). Each file keeps its own format.

What if my video won't fit in 100 MB?

Trim to the part that matters: length is the biggest lever. At 100 MB, a 1-minute clip gets about 13.3 Mbps (1080p, close to the original); trimmed to 30 seconds it gets 26.7 Mbps (1080p, close to the original). 720p is plenty on a phone: 720p has less than half the pixels of 1080p, so the same bitrate looks much cleaner. Most people watch shared clips on a phone anyway. Screen recordings fit more: slides, code and app UI barely change between frames, so a screen recording stays sharp at 100 MB for far longer than camera footage.

Will the file be exactly 100 MB?

It aims to land at or just under 100 MB. 100 MB here means 100,000,000 bytes, so it also fits sites that count 1 MB as 1,048,576 bytes.

What is 100 MB typically needed for?

Common reasons: long screen recordings, lectures and webinars; forms and file-sharing tools with a 100 MB cap; archiving phone videos without filling your storage. Limits vary by site, so check the exact number where you're uploading.

Are my videos uploaded?

Every video format here is compressed in your browser, so nothing is uploaded.

What fits in 100 MB

Any video at 100 MB has the same bit budget, whatever the format: the longer the clip, the lower the bitrate and resolution it can keep.

Clip length	Video + audio bitrate	Realistic quality
1 min	13.3 Mbps	1080p, close to the original
3 min	4.4 Mbps	1080p, high quality
5 min	2.7 Mbps	1080p or 720p
10 min	1.3 Mbps	720p
30 min	444 kbps	360p, fine on a phone

Rough guide for H.264-class video. Static scenes and screen recordings look better than fast action at the same bitrate.

What 100 MB is typically for

Long screen recordings, lectures and webinars

Video won't fit in 100 MB?

Trim to the part that matters
Length is the biggest lever. At 100 MB, a 1-minute clip gets about 13.3 Mbps (1080p, close to the original); trimmed to 30 seconds it gets 26.7 Mbps (1080p, close to the original).
720p is plenty on a phone
720p has less than half the pixels of 1080p, so the same bitrate looks much cleaner. Most people watch shared clips on a phone anyway.
Screen recordings fit more
Slides, code and app UI barely change between frames, so a screen recording stays sharp at 100 MB for far longer than camera footage.
Emailing it? Aim a little lower
Attachments grow by about a third when they're encoded for email, so a file right at an email limit can still bounce.
