How to compress a video for WhatsApp (16MB)
WhatsApp’s in-chat video limit is 16 MB — the tightest cap most people hit. Status and some document sends differ, but a normal chat video above 16 MB will fail or get crushed by WhatsApp’s own encoder.
This page is a free WhatsApp video compressor. Drop an MP4 or iPhone MOV, keep the WhatsApp (16MB) preset, and download a file that actually sends. Encoding stays on your phone or laptop; the original is never uploaded to us.
Long clips at 16 MB need 480p more often than Discord. Strip audio if it is silent B-roll. If you only need the soundtrack (a voice note from a video), use Video to MP3 instead.
iPhone HEVC/MOV files are the usual reason a send fails. Converting to MP4 without lowering bitrate does not help. You have to spend fewer bits per second. On a phone screen, a well-encoded 480p chat video often looks better than WhatsApp’s own panic re-encode of a 200 MB original.
If WhatsApp still re-compresses after you hit 16 MB, send the MP4 as a document where that option exists. For the full walkthrough see WhatsApp video too large.
How to compress a video for free
Three steps. The encoder runs on your device, so private clips never sit on a server.
1
Drop the video
MP4, MOV, WebM, AVI, or MKV. The file is read in this tab — it is never uploaded.
2
Pick a size cap
Discord 20MB, WhatsApp 16MB, email 20–25MB, X 512MB, TikTok, Instagram, or a custom MB. Bitrate is calculated, not guessed.

Download the MP4
Two-pass H.264 in the browser. No watermark, no account, no daily limit.
