Frequently Asked Questions

Why use this instead of CapCut or Handbrake?

For one-off desktop compression, this is faster — no install, no signup, no admin permissions on your work laptop. CapCut is mobile-first and Handbrake is overkill for "make this MP4 small enough to email." Reach for those if you need ongoing editing or batch encoding.

Will it fit my Discord / Slack / email upload?

Use the size hint to dial CRF until the predicted output is under your target — Discord's free tier is 25 MB, Gmail attachments are 25 MB, Slack free is 1 GB. Switching to a smaller resolution preset (720p / 480p) drops size faster than CRF alone.

What formats are supported?

MP4, WebM, MOV, AVI, and MKV up to 500 MB.

How much can videos be compressed?

Typical compression reduces file size by 40-70% with minimal visible quality loss. Bigger gains come from also dropping resolution.

What is the maximum file size?

There's no server limit since processing happens locally on your device. Memory is the only constraint — most laptops handle files up to about 1 GB.
