Compress video for WhatsApp
Take control before WhatsApp's own compressor does — smaller files, your quality choices, and Status-ready sizes.

🔒 Files never leave your device — everything runs in your browser.
WhatsApp's dirty secret is that it re-compresses almost every video you send, and its compressor is tuned for speed, not beauty — that is why videos arrive blurry even on fast connections. Sending a file you have already compressed to a sensible size means WhatsApp's compressor mostly leaves it alone, and what your contact receives is what you chose.
Status videos are stricter: they are capped at 16 MB and trimmed to short segments, so the 16 MB preset below is made for them. For regular chats, a 30–64 MB file sends quickly on mobile data and survives the pipeline well. Everything is compressed on your own phone or computer — your video never touches our servers, because we have none.

Frequently asked questions
Why do my WhatsApp videos look blurry to the receiver?
WhatsApp re-encodes videos aggressively to save bandwidth, and large originals get crushed the hardest. Pre-compressing to a moderate size gives its pipeline little left to squeeze, so far more of your quality survives the trip.
What is the WhatsApp Status video limit?
Status media is capped at 16 MB (and clips beyond 30 seconds are split into segments). The Status preset targets exactly this cap with a built-in safety margin.
Can I send long videos on WhatsApp?
Chats technically accept large files now, but big videos send slowly, eat the receiver's data, and get compressed hardest. For anything over a few minutes, compress to the Chat HD preset or share a link instead.
Is my file uploaded to a server?
No. ConvertUno runs entirely in your browser on your own device. Your file never leaves your computer or phone — there is no upload at all.
Is it really free, with no watermark?
Yes. Processing happens on your device, so serving you costs us almost nothing — no watermark, no account, no file-size limit, no daily quota.
