Video skalieren
1080p, 720p, individuell
Über dieses Tool
Resize a video to a target resolution - 4K, 1080p, 720p, 480p or any custom width/height. Useful for hitting platform upload limits (some services cap at 1080p), saving bandwidth when sharing, fitting older devices that can't decode 4K, or batch-shrinking a folder of clips before archiving.
Privvert keeps aspect ratio by default so you don't end up with squashed footage. Resizing runs in your browser with FFmpeg-WebAssembly - your video is never uploaded, even when it's a private project file.

Häufig gestellte Fragen
Almost always yes - fewer pixels means less data to encode at the same quality setting. A 4K → 1080p resize typically shrinks files by 60-75%.
No. Upscaling can only interpolate; it can't invent detail that isn't there. The output is a smoother but no-sharper version of the input.
1080p (1920×1080) is the sweet spot for desktop quality without huge file sizes. 720p (1280×720) is a safe upload target for everywhere.
Yes - keep 'preserve aspect ratio' on. The tool resizes to fit within your target dimensions without stretching.
Downsizing usually gives a sharper-looking result than the original at the new size, because high-frequency detail is averaged out. Upsizing can't invent detail and just makes the existing pixels bigger, sometimes with a slight smoothing pass.
1080×1920 for vertical (Reels, TikTok, Shorts), 1080×1080 for square, 1920×1080 for standard horizontal. The presets in the tool match these defaults.
