Ban-risk and rate-limit safety on TikTok

Humanized posting delays

TikTok rate-limits per-account publishes. Jitter intervals keep repeat uploads outside the burst pattern that triggers review.

Official API only

TikTok Content Posting API via official OAuth 2.0 with the video.publish scope. No scraping, no session cookies, no unofficial endpoints — the practices that actually get accounts suspended.

Compression before upload

WebCodecs re-encodes on your device — a 100 MB clip becomes roughly 12 MB — so TikTok uploads finish fast and stay inside its size ceiling. Try the compressor.
