How to use the tiktok video resizer

Step 1
Choose a short clip with a clear focal point
Upload an MP4, MOV, or WebM video and use Trim to choose the part you want to export. A cooking step, product demonstration, or talking-head clip is easier to reframe when the main action stays in one area.
Step 2
Check the action throughout playback
The 1080 × 1920 crop is ready when you upload. Drag the preview or adjust horizontal position, vertical position, and zoom. Play the whole clip: the crop stays fixed and does not follow a moving person.
Step 3
Keep a wider scene when the crop loses context
If hands, products, or other people fall outside the crop, switch to Keep whole video. A blur or color background fills the remaining vertical space without changing the original proportions.
Step 4
Download and check the TikTok preview
Export your MP4, then upload it to TikTok. Check that captions and app controls do not cover the subject. Add any captions, music, or timed edits in your preferred editor or TikTok.

Ways to use your tiktok video resizer

Cooking and drink tutorials

Bring the bowl, glass, or preparation area into a vertical frame. Use the full-frame option when a recipe needs both hands and a wide counter in view.

Product demonstrations

Reframe a short landscape product demo for a phone screen. Keep the product label and the movement that demonstrates its use inside the crop.

Talking-head tips

Reuse an already edited short explainer with the presenter centered vertically. Keep the source audio or mute it before adding a new soundtrack elsewhere.

TikTok video resizer questions

What size does this TikTok video resizer export?

This page starts at 1080 × 1920 pixels, a 9:16 vertical canvas. You can choose another aspect ratio or enter custom even dimensions before exporting.

Can I resize a horizontal TikTok video without cutting off the sides?

Yes. Change How should it fit? to Keep whole video. The entire horizontal picture stays visible, with a background above and below it. It will occupy less of the vertical screen than a crop.

Does the TikTok crop follow me as I move?

No. Position and zoom define one fixed crop for the entire clip. Preview your movement before converting; keep the whole video if a fixed frame cannot contain the action.

Can I export several TikTok clips without a watermark?

Yes. A paid plan or active pass lets you resize up to five clips together, with separate trim times for each video. They share framing settings and download as individual MP4 files; batches up to 1 GB also support ZIP downloads. Free users can upload 250 MB and export 10 minutes per clip. Premium supports 20 minutes, Pro 40, and Scale 120.
