Compression tips by format
MP4 videos
Best for sharing. H.264 encoding offers excellent quality-to-size ratio at most bitrates.
WebM videos
Open format with great compression. The tool converts to MP4 for maximum compatibility.
Large recordings
Screen recordings and long clips are scaled to 720p and re-encoded for dramatic size reduction.
Email attachments
Most email providers cap attachments at 10-25MB. Compress to fit the limit easily.
How to compress a video to under 1MB
Large video files can be a major obstacle when sharing via email, uploading to web forms, or posting on social media. Most platforms impose strict file size limits — typically between 5MB and 25MB. Whether you need to compress a video to 5MB, 2MB, 1MB, or even smaller, our free video compressor handles it without excessive quality loss.
The tool uses FFmpeg WebAssembly to re-encode your video directly in the browser. It calculates the optimal bitrate for your target file size, scales the resolution down to 720p if needed, and produces an MP4 file with H.264 video and AAC audio — the most widely compatible format across devices and platforms.
All processing runs entirely in your browser using WebAssembly. Your video files are never uploaded to any server, ensuring complete privacy. The first compression requires a one-time download of the FFmpeg engine (~30MB), after which subsequent compressions start immediately.
Frequently asked questions
What video formats are supported?
We support MP4, WebM, MOV, and AVI input. The output is always MP4 (H.264 + AAC) for maximum compatibility across devices and platforms.
Will my video lose quality?
Some quality reduction is expected when compressing to a smaller size. The tool uses smart bitrate targeting — it finds the highest quality that fits within your size limit. For moderate compression (e.g., 50MB → 10MB), quality loss is usually minimal.
How long does compression take?
Processing time depends on video length and resolution. A 30-second 1080p clip typically takes 15-45 seconds. The first compression requires downloading the video engine (~30MB one-time download). Subsequent compressions are faster.
Are my videos uploaded to a server?
No. All compression happens locally inside your browser using WebAssembly (FFmpeg.wasm). Your videos never leave your device and are never sent to any server.
What's the maximum file size I can compress?
For best performance, we recommend files under 50MB. Larger files will still work but may take several minutes to process, especially on mobile devices.
