Frequently asked questions
What size should TikTok videos be?+
1080x1920 pixels (9:16 vertical). TikTok accepts other sizes but letterboxes or crops them - matching the spec keeps full-screen quality.
Will horizontal video look stretched?+
No. The TikTok preset uses a 9:16 cover crop with an interactive preview, so you can reposition the frame before exporting 1080x1920 without stretching the source.
Does the tool add a watermark?+
No. Output is a clean MP4 with no watermark or branding.
Can I resize a landscape video for TikTok without stretching?+
Yes. Upload it, adjust the 9:16 crop preview, and export the 1080x1920 MP4; the preset crops to fill the frame instead of distorting the video.
