Why WhatsApp rejects videos
WhatsApp works best with MP4 files using H.264 video and AAC sound. MKV, AVI and WMV files, HEVC videos on older phones, and files with AC3 sound often show "This video cannot be sent" or play without sound. This preset fixes all of those and scales the video to 720p, the size WhatsApp itself uses, so it sends quickly.

Use Compress Video for WhatsApp to aim for an exact file size.
Good to know
Output is MP4 with H.264 video (yuv420p, the colour format every player supports), AAC stereo at 48 kHz, and the index moved to the start of the file so playback and uploads begin immediately.

Frequently asked questions
Will WhatsApp compress it again?
WhatsApp compresses most videos it sends as regular media. Starting from a clean 720p MP4 means less is lost in that step.
Do I have to pay or sign up to use the WhatsApp Video Converter?
No. There is no account, no payment and no watermark. The only limit is 1 GB per file, set by what browsers can handle.
Is my file uploaded to a server?
No. The converter runs inside your browser using WebAssembly, so your file is processed on your own device and never sent to us or anyone else.
Can I use it on my phone?
Yes. Open the page in your phone's browser and choose a file. Phones have less memory than computers, so very large files are better converted on a laptop or desktop.
