Compress video for WhatsApp

Per WhatsApp’s help pages, 64 MB for a video sent or forwarded, on all platforms. The same pages give 100 MB as the default on a faster connection, so they are not fully consistent. A video under 64 MB is under both figures, which is why the tool aims for about 63 MB.

WhatsApp’s pages use both. 64 MB is called the maximum on all platforms and the default on a slower connection, at 480p. 100 MB is the default on a faster connection, at 720p. The pages do not reconcile the two, so the preset sits at 64 MB, which is under both.

A 1 GB video is far over the 64 MB maximum, so it has to shrink to about 6% of its size to fit. The tool does that by lowering the bitrate, then the resolution and the frame rate, so a long video comes out much softer. The plan on screen says so before you start. A clip of a minute or two is a smaller cut: according to Apple, one minute of 1080p iPhone video takes 70 to 105 MB.

WhatsApp’s help page states the Status limit as a length: a video of up to 90 seconds. To compress video for WhatsApp status, make the file smaller with the preset above. The tool changes the size, not the length, so a clip over 90 seconds has to be shortened before you use it.

Yes, as a rule. WhatsApp’s help pages say media files are usually compressed when shared, so the quality of what arrives may be lower than the original. That happens inside WhatsApp, after you send, and nothing on this page changes it. What you control is the copy you start from, and the plan above shows its resolution and size before you press Compress video.

WhatsApp says media may arrive at a lower quality than the original because it is usually compressed when shared. Its default resolution is 720p on a faster connection and 480p on a slower one. A size limit is a budget of bits for the whole video, so a shorter clip keeps more detail at any size. For more on that, read compress video without losing quality.

Yes. The tool runs in your browser and adds no watermark: the new file holds only your picture and sound. It works in current Chrome, Edge and Safari, and in Firefox on a computer, and on an iPhone in Safari. For any other size, the full video compressor online takes a size of your own.

No. The video is converted in your browser, on your own device, and is never sent to a server. It reaches WhatsApp only when you send it yourself. Compression does cost some quality, so play the result before you send it.
