Video Compressor

Make videos easier to share. Choose a compression level, reduce picture size or remove sound, then preview and download an MP4.

Video and preview

Plan your compression

Start with a level, then tailor the output for where you want to share it.

Compression level

Keeps proportions without increasing picture size or frame rate. Dimensions use even pixels for MP4 compatibility.

Output formatMP4 · H.264 / AAC

No fixed file size limit. Processing capacity depends on your browser, available device memory and processing engine. Long or high-resolution videos may take a while; keep this page open.

No video upload

The engine runs in this browser. Your selected video is never sent to a server.

Compare size and clarity

Compression re-encodes video and can reduce detail. See the actual size and preview before deciding.

An MP4 ready to share

Exports H.264 video with optional AAC audio. Adjust settings to find the size and clarity you want.

A few things to know

Which videos can I compress?

Reads MP4, MOV, WebM, MKV, AVI, WMV, FLV, MPEG, TS, 3GP, RMVB, OGV and MXF containers, depending on their codecs. Use recent Chrome or Edge. Damaged, encrypted or unusual codecs may not work.

Why is the result larger, and can I choose an exact size?

Size depends on source encoding, picture complexity and settings. Already compressed sources can become larger. Quality levels do not guarantee an exact size. Try lower picture or frame rate limits or stronger compression.

What if processing is slow or fails?

Speed depends on your device, duration and resolution. Try a lower picture limit, close memory-heavy tabs or use a smaller file. Cancelling stops the engine and keeps your video ready to try again.
