Prepare videos that send fast on WhatsApp, even on mobile data, without handing them to a server. Nothing is uploaded, and there’s no account, watermark or limit.
Open this page on your phone or computer and add the video: tap to choose it from your gallery or files, or drop it on the page.
Under “Target size”, keep “WhatsApp (16 MB)” for quick sending, or choose “WhatsApp, larger (64 MB)” for longer clips.
Keep “Max resolution” on Auto. It chooses the sharpest size the budget allows, usually 720p for short clips.
Press “Compress”, tap Download when it's done, then attach the new MP4 in WhatsApp.
WhatsApp treats videos in two ways. Sent from the gallery, a video is re-encoded by the app to save data, which often makes it noticeably softer. Sent as a document, the file goes through unchanged, and since 2022 WhatsApp allows documents of up to 2 GB.
Compressing the video yourself first gets you the best of both. You decide the size and resolution, the clip uploads quickly on mobile data, and the person you send it to gets a sharp video that plays directly in the chat.
The “WhatsApp (16 MB)” preset uses 16 MB, the figure long quoted as WhatsApp's media limit, which still sends in seconds. A one-minute video at 16 MB gets about 2 Mbit/s, enough for clean 720p on a phone screen. For longer clips, the 64 MB preset keeps quality up without making the upload a chore.

A video sent as a document arrives as a file to download rather than playing in the chat bubble, and it can take a long time on mobile data.

A normal video message is the most convenient: it plays in the chat and the recipient can forward it easily. Its drawback is WhatsApp's own compression, which you don't control.
HD sends more detail but bigger files, which can be slow or expensive on mobile data for both you and the recipient.
A document keeps the original perfectly but is often hundreds of megabytes for a phone video, and it appears as a file attachment instead of a playable bubble on some devices.
Compressing to 16 MB or 64 MB here and then sending as a normal video is a good middle ground: small enough to send quickly, and already compact enough that WhatsApp's own processing has far less to strip away.
Files sent as documents can be up to 2 GB. Videos sent from the gallery are compressed by WhatsApp before sending, and very large ones can take a long time or fail on slow connections, which is why a compact file of 16 to 64 MB is the practical choice.
WhatsApp re-encodes gallery videos at a low bitrate to save data. You can choose HD before sending, change the media upload quality in Settings, or compress the video yourself first so you control the quality.
Yes. Status videos are short, so the 16 MB preset is plenty. Long videos are limited by WhatsApp's Status length rules, so trim them to the moment you want to share.
Yes, in Safari on iPhone and Chrome on Android. Keep the page open while it works; phones may pause background tabs. For long 4K videos, a computer is faster and has more memory.
Yes. The video never leaves your phone or computer: it is compressed inside your browser and saved to your device. WhatsApp's end-to-end encryption then protects it in the chat.
MP4 with H.264 video and AAC audio, which is what filetidy produces. It plays on every phone WhatsApp supports, so there's no conversion delay on the recipient's side.
