Frequently asked questions

7 questions

How do I compress a video to send by text?

Choose the Mobile profile (up to 480p). Carriers cap message sizes, so long clips may still be too large.

Can I make a video small enough for email?

Often. There's no exact target-size option, so use the estimate, then Mobile or Heavy for the smallest result.

How much smaller will my video get?

Light is about 30% smaller, Medium about 50% and Heavy about 70%. These are estimates shown before processing.

Will it reduce quality?

Smaller files trade some detail. Web keeps good on-screen quality; Archive keeps the most.

Which formats can I compress?

MP4, MOV, AVI, WebM and MKV in; MP4 (H.264) out.

Is there a file size limit?

Free: up to 2 GB and 30 minutes. Pro: up to 10 GB and 2 hours.

Can I compress a video after burning subtitles?

Yes. Continue from Burn Subtitles to Compress.
