❓ Frequently Asked Questions

How much can I compress a video? ▼

Using our Maximum compression preset, you can reduce file size by up to 90%. A 100MB video can become as small as 10MB.

Will compression reduce video quality? ▼

Our Balanced preset reduces file size by ~50% with almost no visible quality difference. Maximum compression will slightly reduce quality but is still great for sharing.

Is my video safe and private? ▼

100% safe. Your video is processed entirely in your browser using FFmpeg.wasm. Nothing is ever uploaded to any server.

What is the best setting for WhatsApp? ▼

Use the "WhatsApp" preset which compresses to under 16MB (WhatsApp limit) while keeping good quality. Select 480p resolution for best results.

What does CRF mean? ▼

CRF (Constant Rate Factor) controls quality vs file size. Lower CRF = better quality but bigger file. Higher CRF = smaller file but lower quality. CRF 28 is the recommended balanced setting.
