How to Compress a Video for WhatsApp on iPhone (2026)

Why WhatsApp rejects your video

WhatsApp re-encodes every video you send in a chat and won’t take files over 16 MB. A minute of 4K from an iPhone is roughly 170–400 MB, so even a short clip is far over. The limit depends on how you send it:

Where you send it	Limit	Good to know
WhatsApp chat	16 MB	Re-compressed on send
WhatsApp as a document	2 GB	Original quality, no preview
WhatsApp Status	60 s · 16 MB	Longer clips are split
Email (Gmail)	25 MB	Bigger files become a Drive link
Discord (free account)	20 MB	Nitro raises the limit

Method 1 — Free: use iPhone settings

No app needed. These settings make future videos smaller and help with the one you want to send right now.

1. 1

   Step 1: Record new videos in 720p or 1080p

   Settings → Camera → Record Video → 720p HD at 30 fps. A minute of 720p is about 45 MB instead of 170–400 MB in 4K — so a 20-second clip fits WhatsApp as is.

2. 2

   Step 2: Trim the clip in Photos

   Open the video → Edit → drag the yellow handles to keep only the part you need → Done → Save Video as New Clip. Half the length is roughly half the size.

   Step 3: Send it as a document

   In a WhatsApp chat tap + → Document → Choose Photo or Video. Files up to 2 GB go through untouched — but the other person gets a file, not a playable preview.

Method 2 — Video Compressor (exact size)

Video Compressor re-encodes the video on your iPhone and lands just under a target size. Your original stays in Photos, so you can always go back.

1. 1

   Step 1: Pick the video

   Open Video Compressor. Your newest videos come first, each with the size it will shrink to. Tap the one you want to send.

   Step 2: See the size before you start

   The app shows the expected size and why the file shrinks so well — here 1.1 GB of 4K becomes about 28 MB at High quality. No guessing, no trial and error.

   Step 3: Send to → WhatsApp

   Tap Send to and pick WhatsApp. The app aims just under 16 MB, compresses on your iPhone and shows the result — here 47 MB became 10.2 MB. Then tap Share to WhatsApp.

   Step 4: Compare before you send (optional)

   Drag the slider to see the original and the compressed copy side by side. The date is kept, and you choose whether to keep the location.

Troubleshooting

• Still too big?

  Send it as a document (+ → Document). WhatsApp takes up to 2 GB that way and doesn't compress it again.

• Blurry after sending?

  WhatsApp compresses videos again when you send them in a chat. Tap HD before sending, or send as a document to keep every pixel.

• Video from iCloud takes long?

  With Optimize iPhone Storage on, the full video downloads from iCloud first. Stay on Wi-Fi — compression starts right after.
