Fast workflow
Designed to reduce friction with direct upload, quick processing, and one-click export.
Open Video Compress, add your file, then choose the target output and run conversion.
This tool is optimized for video processing and works best with mp4, avi, mov, mkv, webm, flv as inputs.
When processing completes, download the result in mp4, webm, avi and verify quality before sharing.
Video Compress is a privacy-first utility for fast video processing. It helps you move from mp4, avi, mov, mkv, webm, flv to mp4, webm, avi with consistent output quality.
Designed to reduce friction with direct upload, quick processing, and one-click export.
Files are handled in an isolated processing flow with minimal retention and clear user controls.
Outputs are tuned for real use cases across mp4, webm, avi.
A predictable sequence keeps conversion stable across devices and file sizes.
Video Compress accepts mp4, avi, mov, mkv, webm, flv and exports mp4, webm, avi.
The pipeline is designed for privacy-first processing with clear user control over inputs and outputs.
Use high-quality source files, choose the closest matching target format, and avoid repeated reconversion cycles.
Video Compress follows a deterministic conversion flow so results are repeatable and easier to troubleshoot when a file behaves unexpectedly.
Reduce video file size while maintaining the best possible quality.
Videos are uploaded to ConvertCraft's private cloud servers for processing (video compression requires server-side FFmpeg encoding). All files are automatically deleted immediately after processing — no files are stored, shared, or used for any other purpose. Your original video never leaves the secure processing pipeline.
Uses FFmpeg with H.264 or H.265 (HEVC) codec and CRF (Constant Rate Factor) encoding for perceptually optimised compression. H.265 achieves up to 40% better compression than H.264 at equivalent visual quality. CRF encoding automatically allocates bits where they matter most — high-motion scenes get more bits, static scenes get fewer. The balanced preset (CRF 23) is the sweet spot for most use cases.
When a video is too large for email attachments (Gmail 25MB limit), messaging apps (WhatsApp 16MB, Telegram 2GB), social media uploads (Instagram 650MB), or cloud storage limits. Also essential for web embedding to reduce page load times and bandwidth costs, and for archiving large video libraries in less storage space.
