Reduce Video Size to 100 MB on Your Device
Add a video and tap 100 MB. The tool finds the best quality that fits under 100MB, at the video's own resolution, and checks the finished file: it is at most 10,00,00,000 bytes, the stricter way of counting a megabyte, so it passes everywhere. The video is made by your phone or computer and is never uploaded.
How Long a Video Fits in 100 MB
| Video | Sharp | Good | Soft |
|---|---|---|---|
| 1080p (Full HD) | up to 2 min 33 s | up to 4 min 27 s | up to 9 min 31 s |
| 720p (HD) | up to 5 min 35 s | up to 9 min 31 s | up to 19 min 11 s |
| 480p | up to 11 min 45 s | up to 19 min 10 s | up to 34 min 56 s |
A guide, not a promise: busy scenes need more space and talking heads or slides less. The size button shows how sharp your video will look before you start.
Where 100 MB Limits Come From
WhatsApp’s default limit for a video sent as media is 100 MB on faster connections (64 MB on slower ones), according to WhatsApp’s help centre.
What If 100 MB Is Too Small?
The tool keeps the resolution and lowers the quality first. Only when a video can't fit at its own resolution even at the lowest quality does it make the picture smaller, and the result tells you. For example, a 720p video longer than about 9 min 31 s will look soft at 100 MB.
Other sizes: 5 MB, 8 MB, 10 MB, 16 MB, 20 MB, 25 MB, 50 MB. Or pick any limit.
Frequently Asked Questions
How do I compress a video to 100 MB?
Add the video, tap 100 MB and download the result. It is compressed in your browser, keeps its resolution and is checked to be at most 10,00,00,000 bytes.
How long a video fits in 100 MB?
At good quality, about 4 min 27 s of 1080p or 9 min 31 s of 720p video with sound. Longer videos still fit, but look softer.
Is the video uploaded?
No. It is compressed on your own device, so there is no upload wait and no mobile data spent on sending it to a server.
Will the resolution change?
No, unless 100 MB is impossible for that video even at the lowest quality. Then the picture is made smaller to fit and the result says so.
