Frequently Asked Questions

Scaling (or resizing) a video changes its resolution - the width and height in pixels. You can make videos larger or smaller to fit different platforms, reduce file size, or match specific requirements. Common uses include converting 4K to 1080p, creating thumbnails, or fitting videos into specific layouts.

Maintaining aspect ratio preserves the video's original proportions by adding black bars (letterboxing/pillarboxing) if needed, preventing distortion. Stretching forces the video to fill exact dimensions, which can make content appear squashed or elongated. Use aspect ratio preservation for professional content.

Common presets include: 1920×1080 (Full HD/1080p), 1280×720 (HD/720p), 854×480 (SD/480p), 640×360 (360p), and 320×240 (240p). You can also enter custom dimensions in pixels for specialized requirements like product videos, digital signage, or platform-specific formats.

Yes, but upscaling doesn't add detail - it enlarges existing pixels. A 720p video scaled to 1080p will be larger but not sharper. Upscaling is useful for platform requirements or mixing footage, but won't improve quality. For best results, always start with the highest resolution source.

The video is scaled to fit within the target dimensions while keeping its original proportions. Black bars (padding) are added on sides or top/bottom if the aspect ratios don't match. For example, a 16:9 video scaled to 4:3 will have vertical bars.

Stretching (force exact dimensions) changes the aspect ratio, causing visual distortion. A 16:9 video stretched to 4:3 will appear compressed horizontally. Use this only when you need exact dimensions and distortion is acceptable, such as for specific display hardware.

Scaling down (reducing resolution) significantly reduces file size. A 4K video scaled to 1080p can be 70-80% smaller. However, scaling up (increasing resolution) increases file size without adding quality. For maximum size reduction, combine scaling with the video compressor tool.

Input supports MP4, WebM, MOV, AVI, MKV, and most common video formats. Output is always MP4 with H.264 codec and AAC audio, the most compatible format for web, mobile, and social media platforms.

Never. All video processing happens locally in your browser using FFmpeg.wasm. Videos never leave your device, ensuring complete privacy and security. No server uploads, no data collection, works offline after initial page load.

Processing time depends on video length, source resolution, and target resolution. Scaling down a 2-minute 4K video to 1080p typically takes 1-3 minutes. Scaling up is faster. The browser handles all processing, so performance varies by device.
