Frequently Asked Questions
How much can I compress my video?
Depending on the original file and quality setting, you can typically reduce file size by 30-80%. A 100 MB video at 50% quality often becomes 25-50 MB with minimal visible quality loss.
Will compression reduce video quality?
Some quality loss is inherent to compression, but at 50% or above, most viewers won't notice the difference. Use the "High Quality" or "Maximum" presets to minimize visible artifacts.
What formats are supported?
You can compress MP4, WebM, AVI, MOV, and MKV videos. The output format matches your input — upload an MP4, get a compressed MP4 back.
Is there a file size limit?
Maximum upload size is 2 GB. Files are processed server-side using FFmpeg and automatically deleted after 60 minutes.
Can I compress video for email or WhatsApp?
Yes! Set quality to 25-40% (Small File preset) to get videos small enough for email attachments (under 25 MB) or WhatsApp (under 16 MB for most carriers).
Why Compress Videos?
Large video files are difficult to share via email, messaging apps, or social media. Video compression reduces file size by re-encoding the video at a lower bitrate using the H.264 codec (or VP9 for WebM), which is universally supported across devices and platforms.
Our compressor uses FFmpeg's CRF (Constant Rate Factor) mode, which intelligently allocates more data to complex scenes and less to simple ones — resulting in smaller files without the blocky artifacts you get from fixed-bitrate compression.
Best Compression Settings
For sharing on social media or messaging apps, the "Small File" preset (25%) offers aggressive compression that keeps files compact. For archiving or presentations, the "Balanced" preset (50%) provides an excellent quality-to-size ratio. For professional work where quality is paramount, use "High Quality" (75%) or "Maximum" (95%).
