WhatsApp limits the size of videos you can send and compresses them heavily itself. Compressing on your own first gives you a smaller file that still looks sharp.

Compress a video for WhatsApp

Open Video Compressor & Resizer and tap Select video.
Choose a profile:
- Smallest file: maximum space saving, fast to send on WhatsApp and other messengers.
- Balanced: the smallest size that still looks the same on a phone.
- Social Media & Reels: smooth 1080p for Instagram Reels, TikTok and Shorts.
Check the expected size shown before you start.
Tap Compress video, then share the result straight to WhatsApp.

Make it even smaller

Trim the start and end. Need just one part? Use First 1 min or set Start here and End here.
Lower the resolution: shrink 4K to 1080p, 720p or 480p.
Use H.265 / HEVC (PRO): about 30% smaller at the same quality.
Need an exact limit, for example 16 MB? Use Email & Messengers with a target size.

Screen recordings usually shrink the most. Compression runs in the background, so you can leave the app while it works.

Is my video uploaded?

No. Compression runs on your phone: no upload, no account and no watermark. Your original is never changed unless you choose Replace original.
