How to compress a video online

1

Upload your video — drop in an MP4, MOV, MKV, AVI or WebM file. It stays in your browser; nothing is sent to a server.

2

Choose how much to compress — pick a target quality or file size, or let the compressor hit a Discord- or email-friendly size automatically.

3

Compress — the tool re-encodes the video to a smaller size while keeping the quality as high as the target allows.

4

Download — save the compressed video instantly, watermark-free, ready for Discord, email, WhatsApp or the web.

What people compress video for

Discord — get a video under the 25 MB (or 500 MB Nitro) upload limit without a paid boost.
Email & WhatsApp — shrink a clip small enough to attach and send.
Websites & social — reduce file size so pages load faster and uploads finish quicker.
Storage & phones — free up space by compressing large recordings on an iPhone or Android.

Frequently asked questions

How do I compress a video for free?

Upload your video to this free online video compressor, pick a target size or quality, and download the smaller file — no download, no account, no watermark. It runs entirely in your browser.

How do I compress a video for Discord?

Set the target to Discord's limit — 25 MB on the free tier (or up to 500 MB with Nitro) — and the compressor shrinks your clip to fit so you can upload it without a Nitro boost.

Does compressing a video lose quality?

Some quality is always traded for size, but a good video compressor keeps the loss invisible at sensible settings. Choose a higher-quality target to keep it sharp, or a smaller size when the file has to fit a strict limit.

Is this a free alternative to Handbrake?

Yes — it does the core of what Handbrake does (re-encode video to a smaller size) but online, with nothing to install and a much simpler interface. Handy when you just need to compress one video fast.

How do I compress a video on iPhone?

Open this page in Safari on your iPhone, upload the video from your library, compress it, and save the smaller file back — no app to install. It works the same on Android.

Is there an upload limit or watermark?

No watermark, and because the compression happens in your browser there's no server upload cap to work around — the practical limit is your device's memory, not an arbitrary plan tier.

What video formats can I compress?

MP4, MOV, MKV, AVI and WebM. MP4 (H.264) is the most compatible output and the best choice for Discord, email and the web.

How much can I reduce the file size?

It depends on the source, but large phone recordings and screen captures often shrink by 50–90% with little visible difference — enough to clear most upload limits.

Is it safe to compress my video here?

Yes — the video never leaves your device. Compression runs locally in your browser, so your file isn't uploaded to or stored on any server.

Shrink File Size, Keep the Quality

A good online video compressor trades size for quality invisibly. Choose a higher-quality target to keep footage sharp, or a smaller size when the file has to clear a strict limit — you stay in control of the balance.

Large phone recordings and screen captures often shrink 50–90% with little visible difference.
