TikTok displays vertical 9:16 video at up to 1080 × 1920. A phone recording is often 4K/60 with a bitrate of 40–100 Mbps — that is massive overhead for a platform that shows it at 1080p30. We transcode your video to a clean 1080p H.264 MP4 at a smart bitrate, so uploads are fast and quality stays high.

Compression strategy

TikTok target is 1080 × 1920 at 9:16; we downscale larger sources, never upscale.
H.264 (libx264) in an MP4 container is the most compatible combination for TikTok.
FPS is kept at 30 for typical content; we only raise exceptions for source FPS.
AAC audio at 128 kbps preserves voice and music clarity without wasting bytes.
CRF-based encoding (~23) keeps visual quality instead of crushing to an arbitrary size.

FAQ

What video format is best for TikTok?

H.264 MP4 at 1080 × 1920, 30 FPS. It is the most compatible and uploads fastest.

What resolution should I use for TikTok?

1080 × 1920 (9:16). Higher resolutions get downscaled by TikTok anyway.

Does compression reduce video quality?

From a 4K source to 1080p, no — you're matching TikTok's actual display spec. We use quality-based encoding (CRF), so visible artifacts are not introduced.

Does the tool upload my video?

No. FFmpeg runs in your browser via WebAssembly. Your video never leaves your device.
