Compress video to 5 MB
Get any video just under 5 MB. Nibbo picks the resolution and bitrate that look best at that size, on your own GPU, with nothing uploaded.
Where is it going?
Your file never leaves this device
What fits in 5 MB
What the compressor picks for a typical 1080p 30 fps phone clip (about 16 Mbit/s) of different lengths when the limit is 5 MB:
| Clip length | Resolution | Video bitrate |
|---|---|---|
| 30 seconds | 540p | 1,145 kbit/s |
| 1 minute | 360p | 552 kbit/s |
| 2 minutes | 240p | 239 kbit/s |
| 5 minutes | 240p 24 fps | 67 kbit/s |
| 10 minutes | Too long for this size | – |
How it works
- We read your video locally and measure how detailed (SI) and how much in motion (TI) it is.
- From the size you pick we compute an exact bitrate budget, then choose the resolution and frame rate that look best at that budget. Lower resolution with enough bits beats blocky full resolution.
- Your GPU encodes it through WebCodecs. Formats the browser cannot decode go through FFmpeg compiled to WebAssembly.
- If the result is even slightly over the limit, we re-encode with a corrected bitrate, so the file fits.
Questions
Will the file be exactly that size?
It will be just under 5 MB, never over. If the first pass overshoots, Nibbo re-encodes with a corrected bitrate.
Is my video uploaded?
No. Nibbo runs in your browser and compresses the video on your device. You can switch off Wi-Fi after the page loads and it still works.
Why does my video get a lower resolution?
A small file has a fixed number of bits. Spreading them over fewer pixels gives a clean picture; keeping full resolution would make it blocky.
