Frequently Asked Questions
How much can I reduce a video file size?
Compression ratios depend on the source video and the quality setting you choose. A typical 1080p MP4 can often be reduced by 40-70% with minimal visible quality loss at medium compression. Lower quality settings give smaller files but more visible artefacts.
Which video formats are supported for conversion?
Our converters support MP4, WebM, MKV, MOV, and AVI as input formats, with MP4 and WebM as the primary output formats. MP4 (H.264) offers the widest compatibility across devices and platforms.
Does video compression re-encode the video?
Yes. The video compressor re-encodes the video at a lower bitrate using FFmpeg running in your browser. Re-encoding is necessary to reduce file size but does involve some quality trade-off depending on the settings.
Why does my video take a long time to compress?
Video processing is computationally intensive. The compressor runs FFmpeg via WebAssembly in your browser, which is slower than native desktop software. Long videos or high-resolution footage will take proportionally longer.
