TikTok max file size: 287 MB per single upload.

The details

TikTok's maximum file size for a single upload in 2026 is 287 MB. Most creators never hit this ceiling — codec efficiency means even a long, high-quality clip rarely exceeds it.

When the limit actually matters: (1) you're uploading uncompressed or ProRes master files instead of delivery-spec H.264. (2) You're using an old codec (H.264 baseline profile) that bloats bitrate without quality gain. (3) You're working in 4K HDR for a platform that only renders 1080p — you're shipping pixels the player never uses.

Codec + format requirements TikTok prefers: audio at AAC, 44.1kHz stereo, H.264 video (High profile, Level 4.0 or higher), MP4 container. HEVC/H.265 uploads work on most modern platforms but transcode slower on the server side, which can delay the post going live.

Note: 10 min upload widely cited; 60 min rolling out per creator tier.

Common upload failures and fixes: - "File too large" error: re-export at CRF 23 (H.264) instead of constant bitrate. CRF preserves visual quality and cuts file size 40-60% versus high-bitrate CBR. - "Unsupported format": TikTok wants MP4. If you exported MOV or MKV, re-mux without re-encoding (ffmpeg `-c copy`) — no quality loss. - Upload hangs: chunked uploads often fail when the connection is unstable. Wired ethernet or a stable 50Mbps+ uplink resolves most large-file uploads.

The comparison table below shows max file sizes across the platforms most creators cross-post to alongside TikTok — useful when planning a single export that satisfies every destination's cap.

Frequently asked questions

What's the maximum file size on TikTok?

287 MB per single upload as of 2026-05.

Why is my TikTok upload failing?

Most "upload failed" errors on TikTok aren't file-size — they're codec or container issues. Re-export as H.264 MP4 first; only worry about file size if you're over 287 MB.

Can I upload 4K to TikTok?

Yes, up to the 287 MB cap. TikTok will downscale to its native player resolution, so you're paying upload bandwidth for pixels the viewer never sees unless you specifically need future-proofing.

How do I compress a video for TikTok without losing quality?

Use H.264 with CRF 18-23 (visually lossless to nearly-lossless), AAC audio at 192-256kbps. This typically cuts file size 40-60% versus a high-CBR master with no visible quality loss.
