Stop uploading edits that TikTok turns into blur.
Drop an MP4, choose a TikTok-safe preset, and download a cleaner H.264 export — no FFmpeg commands, no app install, no server upload.
Upload MP4 → patch settings → download final video.
Everything runs locally in your browser with FFmpeg.wasm. Your video does not leave your device in this MVP.

TikTok-safe render
Exports MP4 as H.264 High Profile, yuv420p, Rec.709, AAC 48kHz and faststart — settings TikTok handles predictably.
Stable FPS
Converts to constant 60 or 120 FPS so your edit is less likely to become choppy after upload processing.
No install
FFmpeg runs in-browser. Great for a quick MVP and safer for editors because raw videos stay local.
scale 1080x1920 → constant fps → h264 high → yuv420p → aac 48k → faststart
We do not disable TikTok compression.
Every platform can still transcode your upload. EditBoost simply gives TikTok a clean, predictable source file so it has less opportunity to destroy detail and motion.
