TikTok Video Rotator
Sideways footage, upside-down clips, videos that play right on your phone but land rotated once uploaded somewhere else — this tool fixes orientation without needing a full re-edit.
Why a video plays fine on your phone but uploads sideways
This is the single most common reason people reach for a rotator tool, and it's rarely an actual filming mistake. Most phone cameras record video in a fixed sensor orientation and separately store an orientation flag — metadata that tells a video player "display this rotated by X degrees." Your phone's own gallery app reads that flag correctly and shows the video right-side-up. Plenty of other software, upload pipelines, and older or third-party players ignore that metadata flag entirely and just play the raw sensor orientation — which is why a video that looks correct everywhere you've personally checked it can still land sideways once it passes through an unrelated tool or gets uploaded somewhere that doesn't respect the same metadata.
This tool solves both versions of the problem: it can either rotate the actual pixel data of the video (a true fix, works everywhere, unconditionally) or correct the orientation metadata flag directly (faster, smaller file change, but only works if the destination actually reads that flag correctly).
Getting the rotation right the first time
90°, 180°, and 270° cover the vast majority of real cases — a video shot with the phone rotated a quarter-turn, a video recorded upside down, or a clip mirrored from a front-camera recording that needs flipping rather than rotating (a genuinely different operation from rotation, since a mirror flip reverses left-right rather than turning the frame). Preview the result before exporting; a 90° rotation applied in the wrong direction just swaps one sideways video for another sideways video.
What rotating does to your frame dimensions
Rotating a video by 90° or 270° swaps its width and height — a 1920×1080 landscape clip rotated becomes 1080×1920, which happens to land it directly in TikTok's native 9:16 shape. That's a genuine bonus in some cases: a landscape clip shot sideways by accident, when rotated correctly, can end up perfectly sized for TikTok without any additional cropping. A 180° rotation (upside-down fix) doesn't change the dimensions at all, since width and height stay in the same place — only the content flips.
