Free Video Compressor Online — Reduce MP4 File Size by Up to 70%
Compress MP4, AVI, MOV, MKV and WebM videos without visible quality loss. Powered by FFmpeg H.264/H.265. Reduce file size for email, WhatsApp, web hosting or cloud storage. No account.
Compression levels and quality settings
Maximum compression: applies aggressive settings (CRF 32, H.264) — reduces file size by 70-85% with noticeable quality reduction. Best for very large source files or when size is critical. Balanced (recommended): applies CRF 23 settings — reduces size by 50-70% with minimal visible quality loss. The standard setting for most sharing scenarios. Quality preserving: applies CRF 18 — reduces size by 20-40% while maintaining near-original quality. Best for archiving or when quality is critical.
Why your video files are large — and how compression helps
A 1-minute 4K video from a smartphone can easily be 400-600 MB. The H.264 codec (and newer H.265/HEVC) analyzes temporal redundancy between frames — areas that do not change between frames are stored only once rather than repeated. This is called inter-frame compression and is what makes H.264/H.265 70-80% more efficient than raw video. Our compressor uses FFmpeg, the same engine used by YouTube, Netflix and Vimeo for their video processing pipelines.
Reduce video size for specific platforms
WhatsApp: max 16 MB (basic), 2 GB (Business). Email attachment: typically 10-25 MB depending on your provider. Instagram DMs: max 1 GB, but 100 MB or less uploads faster. Slack: max 1 GB but 100 MB or less recommended for fast sharing. Web embedding: 5-10 MB for a 1-minute web video is a good target for fast loading.
FAQ
How much will compression reduce my video file size?
It depends on the source codec and content. H.264 source videos can be reduced by 30-50% more. H.265/HEVC sources compress less further. Videos with static backgrounds (webinars, screencasts) compress more efficiently than fast-action sports footage.
What is the maximum file size for compression?
Videos up to 500 MB per upload are supported.
How long does compression take?
30 seconds to 5 minutes depending on video length, resolution and compression level. 4K videos take longer than 1080p.
Does compression reduce video resolution?
Not by default. The compressed video retains the original resolution. You can optionally reduce resolution (e.g. 4K to 1080p) in the settings for additional size savings.
Which video formats are supported?
MP4 (H.264, H.265), AVI, MOV, MKV, WebM and FLV as input. MP4 (H.264) output is recommended for maximum compatibility.
Can I compress a video on my phone?
Yes. The compressor works in any mobile browser — no app download required. Upload from your phone gallery and download the compressed result directly.
