Trim and cut videos precisely with frame-by-frame scrubbing. Set start/end points visually, preview clips in real-time, and export trimmed videos instantly. No upload required - runs 100% in browser.
Convert videos between MP4, WebM, OGG, MOV, AVI, and MKV formats. Device presets for YouTube, Instagram, TikTok, iPhone, Android. Quality options from fast to high quality encoding.
Merge multiple video clips into one seamless video. Drag-and-drop reordering, preview before export, timeline visualization. Combine videos in any format with automatic re-encoding.
Fine-tune your video's resolution, bitrate, and encoding parameters to hit the exact quality and file size you need. Unlike simple compression, the Video Quality Adjuster gives you granular control over individual encoding settings — CRF value, bitrate ceiling, resolution scaling, and audio quality — so you can make precise tradeoffs rather than relying on a single quality slider.
Dial in exact bitrate and resolution targets to match streaming platform recommendations.
Set high CRF quality with no bitrate ceiling for archival copies where file size is less important than quality.
Cap the bitrate for videos that will be played on slow connections or embedded on bandwidth-sensitive web pages.
Apply consistent quality settings across multiple videos to maintain a uniform look in a video library.
The quality adjuster exposes the key parameters that encoding tools normally hide behind presets. CRF (Constant Rate Factor) controls the baseline visual quality, with lower values producing better quality and larger files. The bitrate ceiling sets a maximum data rate, useful for streaming or platform requirements. Resolution scaling lets you downscale the video while keeping the aspect ratio intact. These controls work together: you might keep CRF low for quality but add a bitrate ceiling to prevent the file from exceeding a target size. The tool shows a real-time estimate of the output size as you adjust each parameter.
For H.264, CRF 18-23 is considered visually lossless to good quality. CRF 28+ introduces noticeable quality loss but yields much smaller files. The right value depends on your content and tolerance for artifacts.
The compressor focuses on reducing file size with simple controls. The quality adjuster exposes individual encoding parameters for precise control over the quality-size tradeoff.
You can increase the resolution numerically, but this won't add detail that wasn't in the original footage. The result will look the same as the original stretched to a larger size.
