Compress video for TikTok before you post

TikTok expects vertical video. BotMart's Social (vertical) preset keeps your clip at 9:16, targets mobile-friendly dimensions (720p free, 1080p on PRO), and cuts file size so uploads finish faster on Wi‑Fi or mobile data.

Why compress before TikTok?

• Faster uploads — Heavy 4K or screen recordings can stall in the TikTok app or Creator tools.
• Correct shape — Output stays vertical (9:16); no extra cropping step in another editor.
• Easier backups — Keep a lighter master on your phone or drive before you post.

Which preset should I use?

Tap Compress for TikTok below—we open the compressor with Social (vertical) already selected. Horizontal exports belong on the YouTube guide or general compressor.

How to compress for TikTok (step by step)

1. Sign in (free account).
2. Open the TikTok compressor and upload your MP4, MOV, or WebM.
3. Confirm Social (vertical) is selected, then start compression.
4. Download the smaller MP4 when processing finishes (free tier includes a short wait with ads; PRO skips ads and raises limits).
5. Upload to TikTok as usual.

Free vs PRO for TikTok

Free works for everyday clips: daily job allowance, size cap, and up to 10 minutes per video. PRO adds higher size limits, 1080p vertical output, more daily jobs, and instant ad-free downloads. See plans for regional pricing.

FAQ

Will TikTok re-encode my video?

Yes. TikTok transcodes after upload. Compressing first still saves you upload time and keeps a manageable file on your device.

Will this crop my video to vertical?

The preset targets 9:16 output. If your source is already vertical, it scales to fit. Horizontal sources need a horizontal preset on compress video or enable orientation matching on upload.

How long are files stored?

Uploads and outputs are removed automatically within 24 hours. Only you can access your jobs while they exist.
