Prepare MP4 and MOV files before uploading to TikTok, so the app receives a clean, full-quality file instead of a blurry copy. Free, unlimited, no sign-up. Your video never leaves your device.
From CapCut, Premiere or your phone, export 1080p or higher at 30 or 60 fps.
Use Lossless first. Switch to HD Re-encode only if the file is HEVC 10-bit, a strange size, or very low bitrate.
In the TikTok app open Settings → Data saver / Upload quality and allow high-quality uploads. On desktop, upload at tiktok.com/upload.
Weak mobile data makes TikTok pick a lower upload quality. Use Wi-Fi and wait until the post finishes processing.
| Quality | Resolution | Frame rate | Video bitrate | Codec |
|---|---|---|---|---|
| Full HD | 1080 × 1920 | 30 fps | 12–20 Mb/s | H.264 High |
| Full HD smooth | 1080 × 1920 | 60 fps | 18–30 Mb/s | H.264 High |
| 2K | 1440 × 2560 | 30 / 60 fps | 25–40 Mb/s | H.264 / HEVC |
| 4K | 2160 × 3840 | 30 / 60 fps | 40–60 Mb/s | HEVC |
Yes. Everything runs inside your own browser using your device's hardware, so there are no server costs, no credits, no file count limit and no resolution limit. The only limit is your device's memory.
It copies the video and audio streams without touching a single pixel, then rebuilds them into a clean MP4 with the index at the front (fast start) and optional metadata removal. MOV files become MP4 automatically.
Use it to change resolution or frame rate, convert to 9:16, fix odd sizes, or when your file uses a codec TikTok handles poorly. It re-encodes at a high bitrate with your device's video encoder.
No. The file is processed on your device and saved back to it. Nothing is sent to a server.
TikTok processes every upload. A clean, correctly sized file with HD upload turned on gives it the best possible starting point, so the posted version stays much closer to your export.
Lossless mode works in any modern browser. HD Re-encode needs WebCodecs: Chrome, Edge, Opera, Samsung Internet, recent Safari and recent Firefox. For large 4K files, use a desktop computer.
