Video Resolution Converteer

Video resolution requirements vary across platforms and Casos de uso—YouTube recommends different resolutions, mobile dispositivos need smaller files, and archival systems may need specific dimensions. Resizing videos to different resolutions is essential for adapting content across diverse viewing contexts.

Common resolutions

Choose from standard resolution presets like 1080p (Full HD), 720p (HD), 480p (mobile-friendly), or define custom dimensions. Each resolution has distinct purposes: 1080p for quality archival and streaming, 720p for fast streaming and web use, 480p for mobile dispositivos with limited bandwidth, and custom dimensions for specific platform requirements.

Two fit modes

Letterbox mode preserves the original aspect ratio, adding black bars if necessary to fit the target resolution—ideal for maintaining the original composition. Crop mode fills the entire target resolution by removing edges—useful for creating square crops from 16:9 videos or adapting to different aspect ratios while keeping the image prominent.

File size reduction

Downscaling resolution dramatically reduces file size. A 4K video (3840x2160) downscaled to 1080p (1920x1080) cuts data by roughly 75%, and further downscaling to 720p reduces data by 84%. For distribution on limited-bandwidth networks or dispositivos with storage constraints, resolution reduction is essential.

Common scenarios

Content creators downscale 4K camera footage to 1080p for web streaming and YouTube carregars, mobile app developers resize videos to phone-optimized resolutions, website owners reduce video dimensions for faster loading, social media managers scale videos for platform-specific requirements, and archivists preserve videos at multiple resolutions for different access dispositivos.

Quality vs. size trade-off

Lower resolutions Cria smaller files that load faster but show less detail. The right resolution depends on your use case—web streaming at 720p balances quality and speed, mobile at 480p prioritizes bandwidth, and archival at 1080p or higher preserves detail for future use.

Real-time conversion

Conversion plays your video in real-time using canvas rendering and MediaRecorder, showing progress. A 5-minute video takes roughly 5 minutes to resize, with estimates provided before processing.

Navegador-based resizing

All resolution conversion happens locally in your navegador. Your video stays on your computer—no server carregars, complete privacy, instant processing.
