Compress Video Online

About this converter

Need a video under an email or chat size limit, or a lighter file for a web page? Compress Video re-encodes your clip to an efficient H.264 MP4 at a lower bitrate (and optionally a smaller resolution), cutting the file size while keeping it watchable.

Unlike upload-based compressors, the whole job runs on your device - so there is no upload wait and your video stays private, even for large files.

Compress Video: good to know

• Drop the resolution (e.g. to 720p) for the biggest size savings on high-resolution footage.
• Use the quality setting to balance size against detail - Low for strict limits, Medium for general sharing.
• Great for hitting email, Discord, and messaging attachment limits without an upload.

How it works

1. Drop your file(s) in the box above (or click to browse).
2. Leave the output set to Compress (smaller MP4) and pick a resolution/quality.
3. Click Convert, then Download your file.

Frequently asked questions

How do I compress a video?

Drop your video above, leave the output as Compress (smaller MP4), pick a resolution and quality under Options, then click Convert and Download.

How small can I make the file?

It depends on the clip, but lowering both resolution and quality can cut the size dramatically - often enough to clear email or Discord limits.

Will compressing reduce quality?

Yes, some - compression trades detail for size. Medium quality looks good for most sharing; use Low only when you need to hit a strict limit.

Is there an upload?

No. Compression happens entirely in your browser, so even large videos are processed without uploading and without an upload wait.

What is the file-size limit?

The free plan handles files up to 1 GB, 5 conversions a day. Pro ($5/month) removes both limits.
