How to Compress Video for TikTok (9:16, under 287MB)

TikTok accepts videos up to 287MB on iOS and 72MB on Android uploads, and heavily favors 9:16 vertical. Horizontal clips get letterboxed and perform worse. AVMint compresses and resizes videos to TikTok-friendly specs entirely in your browser.

Open AVMint Compress

Go to AVMint's Compress tool and drop your clip. Works with MP4, MOV, HEVC iPhone files — whatever your camera recorded.

Target a TikTok-safe size

Set a target around 70MB so both iOS and Android uploads work. H.264 MP4 is TikTok's preferred codec, which AVMint outputs by default.

Resize to 9:16 if needed

If your source is horizontal, use AVMint Resize after compressing to crop to 1080x1920 (9:16). Then save the file and upload from the TikTok app.

Tip

TikTok re-encodes every upload anyway, so don't bother pushing quality extremely high. A clean H.264 MP4 at 6–8 Mbps is more than enough to survive their transcode.

FAQ

Why does my TikTok upload fail on Android but work on iOS?

TikTok's Android upload cap has historically been lower (around 72MB) than iOS. Compressing to ~70MB with AVMint sidesteps this difference entirely.

Should I shoot horizontal and crop, or shoot vertical?

Shoot vertical when possible — you get full sensor resolution in the 9:16 frame. If you must crop from horizontal, AVMint Resize handles the crop without re-uploading to a server.
