Upload in HD.
Stay in HD.
Drop your video, tap Optimize, done. A clean video is kept bit-perfect — not re-encoded at all — and every result gets our HD Lock container optimization plus a measured quality report.
1 · Drop it
Size, resolution, duration and a 0–100 Health score show up while it uploads. Fast parallel upload that retries on bad networks.
2 · Optimize
Fully automatic. Max Quality keeps a good video bit-perfect; low-res, HDR or odd codecs are rebuilt at Ultra quality. Smooth makes a light 1080p file that never lags.
3 · Post
Download it, or Auto Post straight to TikTok through the API — no phone gallery compression in between.
- Every video packet compared by MD5 — proof it was not re-encoded
- Frame count, timing, audio sync and a full decode test on every result
- SSIM / PSNR fidelity scores when a re-encode was needed
- Files are private and deleted automatically after 2 hours
TikTok re-processes every upload on its own servers — no tool can control that. What we do is hand TikTok the cleanest possible file, through the route that skips the app's on-phone compression, and show you the measurements.

What is HD Lock?
Our own TikTok container optimization, applied to every result. It never touches a single frame or sound sample — the quality report proves your video data is unchanged.
Max Quality or Smooth?
Max Quality keeps the original (up to 4K / 120 fps) — best picture, viewers need fast internet. Smooth makes a smart 1080p, max 60 fps, about 4–6 Mbps file that plays without lag for everyone.
iPhone tips
Upload from the Files app, not the photo gallery — the gallery can convert the video and drop 60/120 fps. After posting, do not edit the video inside TikTok.
Is my video private?
Files are stored outside the website in a private folder, only your account can open them, and they are deleted automatically.
