Questions people ask

What size does TikTok use?

9:16, which is 1080 by 1920 pixels for a full HD upload. The tool keeps the pixels inside your frame, so a 1080p landscape clip gives a 608 by 1080 vertical video, and a 4K clip gives 1215 by 2160.

Can I turn a horizontal video vertical?

Yes. That is what the 9:16 preset does. Drag the frame over the subject. For a wide shot with two people, trim the clip into two parts and crop each one differently.

Does cropping reduce quality?

The pixels inside the frame are kept at their original size and re-encoded once at high quality. TikTok compresses the upload again, so start from a clean file.

Do you upload my video?

No. The tool runs entirely in your browser. Your file stays on your device until you post it yourself.

Which browsers are supported?

Chrome, Edge and Safari 17 or newer on desktop and Android. Firefox does not support the video APIs the tool needs yet.
