Everything between export and upload
A focused toolkit that respects your footage.
Media inspector
Full stream report powered by ffprobe: codec, profile, level, GOP-relevant data, bit depth, chroma, colour tags, audio layout and container structure.
Spec compliance check
Every property compared with TikTok's recommended upload settings, with plain-language advice for each warning.
Lossless remux
Stream copy into MP4 with +faststart. Exact frame rate and timestamps preserved. SHA-256 packet hashes compared automatically.
Pro re-encode to 4K60
libx264 High or libx265 Main, target bitrate with VBV, keyframe interval by fps, yuv420p, BT.709, AAC 48 kHz.
Metadata editor
Edit standard fields — title, comment, creation date, display rotation and colour tags — with regular ffmpeg options.
Multithreaded WebAssembly
Uses the multithreaded ffmpeg core when your browser allows it, with a single-thread fallback everywhere else.
Personal activation keys
One key per creator. No passwords, no account to manage — just paste your key.
Usage dashboard
See exports used and remaining this month, plus your full export history.
Zero upload
Files are read locally. Only a tiny job record is sent to count your quota.
