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.

The tool

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.

01

TikTok-safe render

Exports MP4 as H.264 High Profile, yuv420p, Rec.709, AAC 48kHz and faststart — settings TikTok handles predictably.

02

Stable FPS

Converts to constant 60 or 120 FPS so your edit is less likely to become choppy after upload processing.

03

No install

FFmpeg runs in-browser. Great for a quick MVP and safer for editors because raw videos stay local.

Honest promise

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.

After download, upload like this

Turn off Data Saver in TikTok.
Enable HD / high-quality upload if available.
Upload directly — do not send through Telegram/WhatsApp first.
Avoid adding heavy TikTok effects after export.
