Compress video for WhatsApp

WhatsApp crushes the quality and limits the size of the videos you send. The fix is compressing the video first: upload your file, pick a quality level and download a much lighter MP4 that's ready for WhatsApp, Telegram, email or any social network. No sign-up, no waiting.

Compress video without losing quality

Our compressor uses smart encoding (H.264 with bitrate control) to shrink your video as much as possible while keeping the image sharp. You choose the balance: maximum compression for fast sharing, or maximum quality to preserve every detail.

Compress MP4, MOV, MKV, AVI and WebM

Need to compress an iPhone MOV, a heavy MKV or an old AVI? We accept the most common video formats and the result downloads optimized and compatible with any device. You can also convert between formats with our conversion tools.

Huge or heavy video? Shrink it in seconds

4K footage and multi-minute videos can weigh hundreds of megabytes. With the right compression you can cut video size by up to 80% — perfect for freeing up space, uploading to the cloud or sharing big files without hassle.

Compress video on your phone: iPhone and Android

No app install needed. This video compressor runs right in your phone's browser — iPhone, iPad or Android. Open the page, pick the video from your gallery and download the compressed version in seconds.

Private, free and no watermark

Your video is processed directly in your browser: it's never uploaded to our servers, nobody else sees it and no copy is kept. The result is 100% yours — no watermark, no usage limits, completely free.

Frequently asked questions

How do I compress a video online for free?

Upload your video (MP4, MOV, MKV, AVI or WebM), choose a quality level and hit Compress. Within seconds you download a much lighter video. No account, nothing to install.

How do I compress a video to send on WhatsApp?

Compress the video at medium quality: the file size drops dramatically and it still looks great on a phone. Then just attach it on WhatsApp as a document or a regular video.

Can I compress a video without losing quality?

Yes. Pick the high quality setting: compression optimizes the bitrate by removing redundant data, so the video gets lighter with virtually no visible quality loss.

Which video formats can I compress?

MP4, MOV (iPhone videos), MKV, AVI and WebM. The compressed video is delivered as MP4, the most compatible format for phones, computers and social media.

Does it work on my phone?

Yes — it works on iPhone and Android straight from the browser, no app required. Also on tablets and Windows, Mac or Linux computers.

Are my videos private?

Completely. The video is compressed inside your own browser and never leaves your device. We don't store, view or share your files.

Does the video get a watermark?

No. The compressed video comes out clean — no watermark, no logos — and you can compress as many videos as you want, with no limits.
