Why is my video too big to send?

Every platform has a file size cap. WhatsApp stops you at 16MB, Discord at 10MB, Gmail at 25MB. A 1-minute phone video is typically 80-200MB depending on how it was recorded, which is well over most limits. Compression reduces the file size by lowering the bitrate (data per second), which reduces quality slightly but makes it sendable.

How much quality will I lose?

For clips under 3 minutes, the difference is barely noticeable on a phone screen. For longer videos compressed to small limits (like 10MB), you will see some degradation. We always compress at the highest quality that fits your target, auto-downscale resolution (1080p to 720p) before destroying quality, and always show you the predicted output before you click Compress.

Does it work on iPhone and Android?

Yes. On Safari 17 and later on iPhone, and recent Chrome on Android, compression runs locally on your device with hardware acceleration. On older phones we fall back to a slower in-browser path on the same device. Either way, upload from your camera roll, pick a platform, and download. No app to install.

Is my video stored anywhere?

No. Compression runs entirely in your browser, so your video never leaves your device. There is nothing for us to store, analyse, or share. The Android app is fully offline and has no internet permission at all.

Can I trim, mute, or change the output format?

Yes. Trim with a dual-handle slider on the review screen, tick 'Mute audio' in Advanced settings to strip the soundtrack, and switch to MOV, MKV, or WebM output if you need something other than the default MP4.

Which input formats are supported?

MP4, MOV, AVI, MKV, WebM, WMV, FLV, M4V, MPEG, MPG, 3GP, VOB, TS, M2TS, and OGV. If your video plays in any modern player, we can almost certainly compress it. Files up to 2 GB are supported.

Your video is compressed entirely inside your browser on your own device. The video data never uploads to any server. Hardware-accelerated where available, usually 10 to 20 seconds for a typical clip.

On a small number of older browsers we fall back to a slower in-browser engine running on the same device. Either way, your file never leaves your computer. There is nothing for us to store, analyse, or share.

Zero upload: bytes stay on your device.
No retention: there is no upload to retain.
Always: no account, no watermark, no install.
