How big is a TikTok video file?
SnaqTik · 2026-10-07
A typical 30-second TikTok is roughly 3–8 MB in standard quality and 8–20 MB in HD. The MP3 of the same clip is under 1 MB. Here is how to plan storage and mobile data.
Rule-of-thumb sizes
| Length | Standard MP4 | HD MP4 | MP3 |
|---|---|---|---|
| 15 s | 1.5–4 MB | 4–10 MB | ~0.25 MB |
| 30 s | 3–8 MB | 8–20 MB | ~0.5 MB |
| 60 s | 6–15 MB | 15–40 MB | ~1 MB |
| 3 min | 18–45 MB | 45–120 MB | ~3 MB |
Busy scenes (dance, gaming, confetti) sit at the high end; talking heads at the low end. Bitrate is the reason — see what bitrate means.
Planning storage
100 average clips in HD take about 1–2 GB; in standard quality about half that. A phone with 5 GB free can hold several hundred clips comfortably.
Saving mobile data
- Download over Wi-Fi when you can — the size you download is the size you pay for.
- Choose standard over HD for clips you will only watch on the phone.
- If you only want the music, the MP3 is 10–20× smaller.
Frequently asked questions
Why is my file bigger than the table?
Long or very detailed clips, or HD versions with high bitrate, can exceed these ranges. They are typical values, not limits.
Does a photo slideshow count as a video?
Saved as images, each photo is usually 100–500 KB. Saved as a video, size depends on length like any clip.
Can I shrink a file afterwards?
Yes, with a compressor — see sending large video files.
