How it works
- Choose a video. It stays on your device.
- Pick the size you need. Altols works out the bitrate and resolution that fit.
- Your browser re-encodes the picture as H.264 and copies the sound across untouched.
- Download the MP4.
Frequently asked questions
Why does my compressed clip look soft?
Size is bitrate multiplied by length. A 3-minute video squeezed into 20 MB only has about 850 kbps for picture, so Altols lowers the resolution to keep it clean rather than blocky. Trim long clips first for a sharper result.
Will it still play in Discord?
Yes. The output is a standard MP4 with H.264 video, which Discord previews inline on desktop and mobile.
Do I need to aim below 20 MB?
Altols aims about 4% under your target to leave room for the file container, so a 20 MB target produces a file Discord accepts.
Is my video uploaded anywhere?
No. Altols uses your browser's built-in video encoder, so the video is processed on your device and never leaves it.
Is there a size limit?
Free compression works on videos up to 100 MB. For larger videos, up to 1 GB, a 24-hour pass costs $2.99 USD.
