Compress Video to 100MB
100MB is a genuinely generous ceiling — typical of free-tier upload widgets and guest file-sharing forms that don't require an account or paid plan. If a platform's limit is measured in the hundreds of megabytes rather than tens, this targets that exact number instead of a quality guess.

Hits an exact 100MB target — fits generous free-tier upload widgets and guest file-sharing forms
Enough headroom for longer clips or higher resolution than the smaller size targets allow
Longer source videos are compressed only as much as needed to stay under the limit
For the loosest common ceiling
Some upload widgets and guest file-sharing tools allow a genuinely large file before asking for an account or a paid tier — often in the 100MB range. Target-size mode calculates the bitrate needed to land your video at exactly 100MB regardless of source length, so a longer or higher-resolution clip that would otherwise be several times over a smaller limit fits with real quality headroom to spare.
Recommended settings
What we'd pick for this job. After choosing a file, resolution sits right under the compression settings, crop is under “Resize / crop”, and codec is under “Advanced settings”.

Pre-filled — enough for several minutes of video.

Plays anywhere; switch to H.265 for a little extra quality per MB.

There's room for 1080p on shorter videos; step down for long ones.

How much video fits in 100MB?
Approximate length at typical streaming bitrates, with 128kbps audio. Target-size mode works out the exact bitrate for your clip automatically — this just shows what to expect.

Tips for the best result
Room for real length
100MB holds about 2½ minutes of 1080p or 5 minutes of 720p at streaming quality — enough for talks, tutorials, and short films.
Large sources take longer
Files over 200MB are processed on our server rather than in your browser. They're deleted automatically once you've downloaded the result.
Trim before you compress
Every second you cut is size saved at full quality. Removing a slow intro or a long ending is usually worth more than an extra compression step.
Start from the original file
Compression is lossy, so re-compressing a video that has already been shrunk (or sent through a chat app) stacks artifacts. Always work from the camera or editor export.

Frequently Asked Questions
Free-tier upload widgets and guest file-sharing forms that don't require creating an account often allow a file in this range — well above the tighter limits smaller web forms enforce.
Generally yes — 100MB gives a lot more bitrate headroom than the smaller targets, so even a several-minute clip can hold up well, especially at 1080p or below.
Quality presets target a visual-quality level and let the file size land wherever it lands. This targets an exact byte count instead — useful when a hard limit, not visual quality, is what actually matters.
No — if your source file is already under the target, compressing further won't help. This tool is for videos that start out larger than 100MB and need to come down to fit.
For files under 200MB, compression happens entirely in your browser — your video never leaves your device. Larger files are processed on our server and deleted automatically after a short period.
