Resize a Video, Every Setting: Reels, Fit vs Fill, Presets, Percent

Every setting of the free video resizer on a 1080p bike-ride clip with music. Before the run it shows 1920x1080 → 1280x720 and that the sound is copied — and the 720p export has all 264 frames and the soundtrack byte for byte. Presets are free to 1080p (1440p and 4K are Pro); platform frames cover Reels, TikTok, Shorts, Feed, Square, YouTube and more. On Reels, Fit keeps 16:9 and says so, Fill crops to 9:16 (608x1080, or the exact 1080x1920 with Allow enlarging), Stretch distorts. Exact sizes, percent (50% = 960x540), long edge, and four filters. Nothing is uploaded.

Resize a Video, every setting, on a 10-second 1920x1080 clip with a soundtrack. Before anything runs the rail shows the result — 1920x1080 → 1280x720 at the default 720p — and that the frames are re-encoded while the sound is copied; the export has all 264 frames and the audio byte for byte. Presets run from 240p to 1080p free; 1440p and 4K are Pro. Platform frames are each platform’s published size: Reels, TikTok and Shorts (9:16), Feed (4:5), Square, YouTube, Pinterest, LinkedIn, Facebook and X. On Reels, Fit keeps the whole picture, so a landscape clip stays 16:9 — and the page says so and points to Fill. Fill crops to 9:16: 608x1080 without enlarging, the exact 1080x1920 with Allow enlarging (with a note that enlarging cannot add detail). Stretch fills the frame by distorting it. You can also set an exact width and height, a percentage (50% = 960x540) or a long edge, and choose the resampling filter: Lanczos is the sharpest, Nearest keeps hard edges hard. Free: one video up to 100 MB and 5 minutes, up to 1080p. Pro: 4K and batches. Nothing is uploaded.
