Mixed formats are fine. 2. **100 MB is preset.** Every file is compressed to land at or just under 100 MB. You can switch to another size, or a percentage to reduce by. 3. **Compress.** Click Compress. Each video keeps its format and is processed right in your browser. 4. **Check and download.** Check the new sizes, then download each file or all of them as a ZIP. ## Good to know - 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. - 100 MB here means 100,000,000 bytes, a little under the 104,857,600 bytes some sites mean, so the result fits either way. - 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 - Forms and file-sharing tools with a 100 MB cap - Archiving phone videos without filling your storage Limits vary by site and change over time; check the exact number where you're uploading. ## 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. ## Other video sizes - [Compress video to 25 MB](https://www.converterrr.com/compress-video-to-25mb): Email attachments - [Compress video to 50 MB](https://www.converterrr.com/compress-video-to-50mb): Portals & bigger uploads ## 100 MB for a specific format [Compress MP4 to 100 MB](https://www.converterrr.com/compress-mp4-to-100mb) ## Compress video to 100 MB: frequently asked questions ### How do I compress a video to 100 MB?
